I lost it all (this my old rogerver bcashy troll account btw) I don’t even know how to start but as of yesterday I’m officially broke, I ruined my life and future. I’m a 23yrs guy, my journey with Bitcoin started in 2014. I bought it to actually use it not sure if people do that nowadays? but The HODL journey didn’t start until the beginning of 2017 as I notice the $ value in my blockchain wallet steadily increasing didn’t even know how or why it was increasing I thought it was a glitch making me free money for this reason I decided to go ALL IN I dumped my life saving into Bitcoin. price was around 1-2K $ and I was able to get 11 BTC in total. Unfortunately before the Bullrun start I lost around 4 coin due to ICO"s scams and just buying shitcooins in poloniex with zero trading knowledge(had a great time with the trollbox). After my loss I took my coins out of the exchange and held in a cold wallet, Fast forwards September 2017 the price kept going up I couldn’t even believe it specially after it broke past 10k I was so euphoric matter fact I was chilling in here, in this subreddit celebrating with everyone posting memes etc.. When BTC hit 20k my greedy asss still didnt wanna sell I didn’t have a price target I though it will keep going up forever. It was going so quick I couldn’t even process what was happening I told my siblings I was rich they told me to sell this bubble but I said "HELL NO! I was part of the moonboy gang we don’t sell we HOODL" I was 19 at the time. seeing this type of money was unreal I had more than 6 fucking figures in my wallet. Eventually we topped out at 20k I didn’t sell although the price kept going down and down and Depression started to hit after we dropped below 10k specially when it went down more near the 3k level I started to regret everything kicking my self for not listening to my siblings when they told me sell. Nonetheless I still had faith in Bitcoin and knew one day we will recover but I needed to accepted the fact that it might take months maybe years to get back to ath. for this reason I disconnected from the crypto community I had to forget about Bitcoin so I shifted my focus somewhere else luckily I stumbled across this popular game called “Fortnite” it took all my time and distraction away from my crypto for a good year or two I barely even noticed the peak of 2019. Anyways mid-late 2019 I got heavy in the stock market I started to see all these guru make insane amount of money just day trading. I was more of an investor type guy but I consumed so much information about day trading and how the psychological aspect is so important, I guess I mastered a bit of that by holding Bitcoin throughout the bear market. Anyways recently in August during the Bitcoin rally I though I had enough skills and decided it was finally time for me to trade Bitcoin specially because it was tradable 24/7 I wanted to start increasing my money and stop sitting on my coins I've had enough of the bear market I thought it was gonna be another P&D episode specially after I started to get deeper in the Crypto community and understood how price moves. I used to be Bitcoin maximalist but then I started to notice the suspicious activity around bitcoin, I came to realize that bitcoin was not the same as it was before, these toxic unregulated entities have turned bitcoin into a giant ponzi playground with everyone being brainwashed by these crypto twitter advocates who are nothing but CZ binance acting puppets. I know it sound crazy but it’s true, the receipt it out to the public, the price is manipulated by Tetther Mafia and these scam exchange. I don’t believe in conspiracy but neither do I believe in coincidence, I witnessed this fraud my own eyes, Whale-alert notified me every time Tetther printed new money and sent it to exchanges and next thing you the price went up. Ever since they added derivative I assume they manipulate the price in spot to liquidate future traders. This whole rally was propt by Tetther mafia using the overall condition in the market as an excuse to attempt artificial FOMO and bring real liquidity in this fake liquidity pool. As the fraud was getting more obvious I started to despise Bitcoin and traded the ponzi based off emotions I neglected the technicals I didn’t have risk management and eventually got liquidated. This is my 3yr+ journey went from 11 btc to 0.. I feel horrible,sad, hopeless and disappointed this was my whole networth vanished in 1-2month. I deprived myself from so many things these last few years hoping my investment grows enough to fund my future. My family still think I’m holding Bitcoins I feel so bad I let them down not sure I'll be able to recover from this. Ps: for those saying Tetther is an old conspiracy trust me this time is different and incomparable to the previous years, the fraud is fully transparent now. Their activity has been very suspicious and concerning lately I’m sensing a major exit-scam. this will impact the whole crypto space because this unbacked counterfeit USD holds most if not all the order book liquidity.
Hey, I used to use coinbase to buy a variety of crypto with my CIBC visa but coinbase no longer accepts it for purchases. is there another platform that I can purchase crypto like kyber, link, tezos, eth, brave, etc with my bank card?
Dragonchain Great Reddit Scaling Bake-Off Public Proposal
Dragonchain Public Proposal TL;DR:
Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and postsper Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625. Watch Joe walk through the entire proposal and answer questions onYouTube. This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!
I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale. For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube. We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoC
In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks. 24 hours in 4 minutes (YouTube): 24 hours in 4 minutes The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period. Tooling to reproduce our demo is available here: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired. Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity. TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block. TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain. With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times. We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment. Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in Scaling
Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems. We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node. Getting started is easy...
Download Dragonchain’s dctl
Input three commands into a terminal
Build an image
More information can be found in our Get started documents.
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain. Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain. After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks. Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD. For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments. Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users. Over a 5 day period, your scaling PoC should be able to handle: *100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes. Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum. Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node. Examples:
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users. All of Reddit's Transactions on Blockchain (month) Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees. Reddit Internal Token Transaction Fees Reddit Ethereum Token Transaction Fees When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here. Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here. In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here. A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible APIs should be well documented and stable
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected. Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR. Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus points Public, third-party implementation review available or in progress
Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).
Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open Source
The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group. https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html
In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney. Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects
Verify no conflict of interest
Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
Obtain legal approval
Approval from corporate, parks, and other business units
Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
Trademark searches conducted for the selected name Dragonchain
Obtain IT security approval
Manual review of OSS components conducted
OWASP Dependency and Vulnerability Check Conducted
Obtain technical (software) approval
Offer management, process, and financial plans for the maintenance of the project.
Meet list of items to be addressed before release
Remove all Disney project references and scripts
Create a public distribution list for email communications
Remove Roets’ direct and internal contact information
Create public Slack channel and move from Disney slack channels
Create proper labels for issue tracking
Rename internal private Github repository
Add informative description to Github page
Expand README.md with more specific information
Add information beyond current “Blockchains are Magic”
Add getting started sections and info on cloning/forking the project
Add installation details
Add uninstall process
Add unit, functional, and integration test information
Detail how to contribute and get involved
Describe the git workflow that the project will use
Move to public, non-Disney git repository (Github or Bitbucket)
Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney. The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

A NFT (non-fungible token) blockchain project called VIMWorld (www.VIMWorld.com) will allow for all types of gaming including older Board games and newer AAA games to store game IP in a NFT. The NFT's are called VIMS which are linked into the ecosystem VIMWorld, and the token used is called EHrT (Eight Hours Token) currently available on Bitrue (rumor - new exchange listing is imminent, maybe Binance). Game developers and Partners can quickly utilize the NFT VIM and integrate their IP which is then stored on the blockchain and can be used across games including their already selling product called the PlayTable (www.playtable.com). The team just paid out $250 ad-hoc rewards to their S-Tier node holders, not part of the VIMPool rewards which will be released soon paying out 5% every 2 weeks of all $EHrTs spent in the gaming ecosystem. A VIM can be described as Virtually Integrated Metadata which is the core of the 8Hours (www.8hoursfoundation.org) platform meta system that is built on VeChainThor blockchain and stores metdata such as data and transaction history and functions as a memory capsule, a collectible, a digital wallet (storing $EHrTs, the token) and a tool for game play and human connection. VIMS can also be linked to a physical object in the real world. Partners Advisors to the project include:
Glen Schofield - Prolific name in AAA game industry, 3x Call of Duty, grossing $1B+
Sean Barger - Gaming industry veteran who has published over 55 titles, most notably "Tetris"
Kris Alexander - Chief Strategist at Akami, Built business from $0 to $100M+
Jateen Parekh - First employee worked on the Kindle project. Co-founded Jelli and was acquired by the largest media company, iHeartMedia.
Shen Bo - Founding partner of Fenbushi. He is with Bitcoin and DACs. He first worked with Shanghai Huaji Internet Holding as CEO
Kai Huang - Co-creator of the multi-billion dollar Guitar Hero franchise, and co-founder of RedOctane.
Ray Hatoyama - Ex-Pokemon advisor, Ex-Hello Kitty CEO and director of LINE and Mitsubishi
Michael Katz - with 25 years experience in the video game entertainment sector. Industry experience includes Mattel, Coleco, (Donkey Kong and Pacman), Atari’s video game division, President ofSEGAEntertainmentUSA.
Competitors: enjin coin is more of a market place to buy gaming items whereas 8Hours aims to store your gaming life/history on an NFT which is unique and can contain special colored tokens/companions which add to the value of it and utilized across games on any device where a partner has integrated their IP. From an AMA with CEO John Dempsey of 8Hours Foudation, this stood out for me: "we're under NDA for several major companies with big household name brands. These are companies that everyone is familiar with and we can flood their communities with our EHrTs and VIMs. We can't name any right now, but these titles are under development. We've already worked with huge board game brands like Asmodee for Catan and Ticket to Ride. Our partnership deals are being made to create revenue, which we are feeding back into the ecosystem to create more and more value. Larger IPs are being signed which aren't board games, but a greater firt for EHrTs and the VIM economy in general. We do work with smaller indie firms, too, for the creation of unique content (over a dozen developers have submitted / created games for PlayTable) Circulating Supply - 1,854,037,961 Max Supply - 10,000,000,000 Market Cap - $27,549,886

Stakenet (XSN) - A DEX with interchain capabilities (BTC-ETH), Huge Potential [Full Writeup]
Preface Full disclosure here; I am heavily invested in this. I have picked up some real gems from here and was only in the position to buy so much of this because of you guys so I thought it was time to give back. I only invest in Utility Coins. These are coins that actually DO something, and provide new/build upon the crypto infrastructure to work towards the end goal that Bitcoin itself set out to achieve(financial independence from the fiat banking system). This way, I avoid 99% of the scams in crypto that are functionless vapourware, and if you only invest in things that have strong fundamentals in the long term you are much more likely to make money. Introduction
Stakenet is a Lightning Network-ready open-source platform for decentralized applications with its native cryptocurrency – XSN. It is powered by a Proof of Stake blockchain with trustless cold staking and Masternodes. Its use case is to provide a highly secure cross-chain infrastructure for these decentralized applications, where individuals can easily operate with any blockchain simply by using Stakenet and its native currency XSN.
Ok... but what does it actually do and solve? The moonshot here is the DEX (Decentralised Exchange) that they are building. This is a lightning-network DEX with interchain capabilities. That means you could trade BTC directly for ETH; securely, instantly, cheaply and privately. Right now, most crypto is traded to and from Centralised Exchanges like Binance. To buy and sell on these exchanges, you have to send your crypto wallets on that exchange. That means the exchanges have your private keys, and they have control over your funds. When you use a centralised exchange, you are no longer in control of your assets, and depend on the trustworthiness of middlemen. We have in the past of course seen infamous exit scams by centralised exchanges like Mt. Gox. The alternative? Decentralised Exchanges. DEX's have no central authority and most importantly, your private keys(your crypto) never leavesYOUR possession and are never in anyone else's possession. So you can trade peer-to-peer without any of the drawbacks of Centralised Exchanges. The problem is that this technology has not been perfected yet, and the DEX's that we have available to us now are not providing cheap, private, quick trading on a decentralised medium because of their technological inadequacies. Take Uniswap for example. This DEX accounts for over 60% of all DEX volume and facilitates trading of ERC-20 tokens, over the Ethereum blockchain. The problem? Because of the huge amount of transaction that are occurring over the Ethereum network, this has lead to congestion(too many transaction for the network to handle at one time) so the fees have increased dramatically. Another big problem? It's only for Ethereum. You cant for example, Buy LINK with BTC. You must use ETH. The solution? Layer 2 protocols. These are layers built ON TOP of existing blockchains, that are designed to solve the transaction and scaling difficulties that crypto as a whole is facing today(and ultimately stopping mass adoption) The developers at Stakenet have seen the big picture, and have decided to implement the lightning network(a layer 2 protocol) into its DEX from the ground up. This will facilitate the functionalities of a DEX without any of the drawbacks of the CEX's and the DEX's we have today. Heres someone much more qualified than me, Andreas Antonopoulos, to explain this https://streamable.com/kzpimj 'Once we have efficient, well designed DEX's on layer 2, there wont even be any DEX's on layer 1' Progress The Stakenet team were the first to envision this grand solution and have been working on it since its conception in June 2019. They have been making steady progress ever since and right now, the DEX is in an open beta stage where rigorous testing is constant by themselves and the public. For a project of this scale, stress testing is paramount. If the product were to launch with any bugs/errors that would result in the loss of a users funds, this would obviously be very damaging to Stakenet's reputation. So I believe that the developers conservative approach is wise. As of now the only pairs tradeable on the DEX are XSN/BTC and LTC/BTC. The DEX has only just launched as a public beta and is not in its full public release stage yet. As development moves forward more lightning network and atomic swap compatible coins will be added to the DEX, and of course, the team are hard at work on Raiden Integration - this will allow ETH and tokens on the Ethereum blockchain to be traded on the DEX between separate blockchains(instantly, cheaply, privately) This is where Stakenet enters top 50 territory on CMC if successful and is the true value here. Raiden Integration is well underway is being tested in a closed public group on Linux. The full public DEX with Raiden Integration is expected to release by the end of the year. Given the state of development so far and the rate of progress, this seems realistic. Tokenomics 2.6 Metrics overview (from whitepaper)
Ticker: XSN. Currency type: Coin.
Consensus: Minting Proof of Stake, Trustless Proof of Stake.
XSN is slightly inflationary, much like ETH as this is necessary for the economy to be adopted and work in the long term. There is however a deflationary mechanism in place - all trading fees on the DEX get converted to XSN and 10% of these fees are burned. This puts constant buying pressure on XSN and acts as a deflationary mechanism. XSN has inherent value because it makes up the infrastructure that the DEX will run off and as such Masternode operators and Stakers will see the fee's from the DEX. Conclusion We can clearly see that a layer 2 DEX is the future of crypto currency trading. It will facilitate secure, cheap, instant and private trading across all coins with lightning capabilities, thus solving the scaling and transaction issues that are holding back crypto today. I dont need to tell you the implications of this, and what it means for crypto as a whole. If Stakenet can launch a layer 2 DEX with Raiden Integration, It will become the primary DEX in terms of volume. Stakenet DEX will most likely be the first layer 2 DEX(first mover advantage) and its blockchain is the infrastructure that will host this DEX and subsequently receive it's trading fee's. It is not difficult to envision a time in the next year when Stakenet DEX is functional and hosting hundreds of millions of dollars worth of trading every single day. At $30 million market cap, I cant see any other potential investment right now with this much potential upside. This post has merely served as in introduction and a heads up for this project, there is MUCH more to cover like vortex liquidity, masternodes, TOR integration... for now, here is some additional reading.

It started with sending $20 worth of BTC from Binance to Munn wallet. Got my first confirmation in less than 5 minutes which made it spendable. From there, I topped up my phone with Bitrefill, fed some chickens on https://pollofeed.com/, You can still see seeds in the ground, they're probably sleeping right now:). Then played some Lightning-roulette.com, started with 50c, got it quadrupled then lost it all. After that and while surfing Reddit, saw a post of this guy who newly invested in crypto so I threw him a Silver Award from Bitrefill again. Then I wanted to buy some BTC merch from https://cryptoshirt.io but was expensive, so I used https://fixedfloat.com/ to convert my Sats to ETH to buy a blockchain domain :) FLICKING POWERFUL. Not a single transaction failed or took more than 2 seconds.

Ahead of Migration to Symbol, Simplex Offers Fiat On-Ramp to Buy XEM
Simplex provides fiat on-ramp infrastructure to several cryptocurrency exchanges, brokers and wallets.
https://preview.redd.it/xu0x98n0r0w51.png?width=880&format=png&auto=webp&s=bf68a66d608a1f0cd78a09eec28a58f34f1fb33b XEM, NEM’s native token on the original NEM blockchain (NIS1), can now be purchased using credit and debit cards thanks to a new partnership with crypto payment gateway, Simplex. Simplex provides fiat on-ramp infrastructure for several cryptocurrency exchanges, brokers, and wallets. The agreement will allow XEM holders to conduct and settle crypto transactions, a grey area of business where a gauntlet of KYC requirements and other regulations kick in. NEM’s userbase will benefit from Simplex’s fiat credit and debit purchase options and the support will prepare XEM holders for the upcoming launch of Symbol from NEM, its new enterprise-grade blockchain solution. “This partnership will provide an easy global on-ramp to XEM, enabling access to Simplex’s extensive network of exchanges globally. By providing users with greater flexibility in purchasing, Simplex will broaden the reach of XEM,” the company said. Simplex often charges 3.5 percent of a transaction, with a $10 minimum purchase amount. Moreover, the company applies various restrictions, including a $20,000 maximum for daily transactions when using a credit or debit card, as well as a $50,000 maximum monthly limit. Israeli-based Simplex combines crypto payment processing with fraud prevention technology and also provides a KYC opt-out feature for purchases less than USD $150. This amount is calculated for the entire lifetime of the user. Further, the startup enables merchants to accept diverse payment methods, including credit card deposits and purchases, with zero exposure to chargeback risk. Simplex has already signed partnerships with leading crypto exchanges, including Binance and Huobi, among others, to enable users to buy cryptocurrencies with their credit cards. Most recently, it has added support for Bitcoin SV, the cryptocurrency spearheaded by the self-proclaimed creator of Bitcoin, Craig Wright. Speaking on today’s announcement, Nicholas Pelecanos, head of trading at NEM said: “We’re excited to make XEM more globally accessible through Simplex’s vast network of partners and exchanges. Simplex’s user experience is unparalleled, and we’re thrilled to work with this industry behemoth to extend NEM’s global reach. This will enable anyone, anywhere, to have a foray into NEM and the digital assets space, democratizing access and propelling the industry forward to the next phase of adoption.” Source
Hướng dẫn mua tiền ảo Bitcoin tại thị trường Việt Nam
Nhiều người khi mới bắt đầu manh nha nghĩ đến việc thử sức với kênh đầu tư tiền ảo thường sẽ nghĩ đến việc mua tiền ảo ở đâu, làm thế nào để mua tiền ảo,…Nội dung bài viết dưới đây sẽ hướng dẫn cho bạn phương pháp cơ bản nhất để mua tiền ảo Bitcoin an toàn và hiệu quả.
Mua tiền ảo Bitcoin ở đâu?
Hiện nay có hai cách mua bán Bitcoin thông dụng nhất cho người chơi đó là mua trên các sàn giao dịch tiền ảo hoặc mua ở “chợ đen”. Mỗi phương thức mua đều có những ưu và nhược điểm nhất định mà bạn nên tìm hiểu để có quyết định phù hợp nhất.
Mua tiền ảo bitcoin ở các sàn giao dịch tiền ảo
Mua tiền ảo trên các sàn giao dịch là cách thức thông dụng và phổ biến nhất của những người chơi tiền ảo trên khắp thế giới. Ưu điểm khi mua trên các sàn giao dịch là đảm bảo sự uy tín, chất lượng. Hạn chế được các rủi ro bị lừa đảo khi thực hiện các giao dịch. Hầu hết các sàn tiền ảo sẽ sử dụng tiền VNĐ nên dễ dàng và nhanh chóng. Tuy nhiên, mức phí bạn phải trả sẽ cao hơn so với bình thường. Bởi các sàn thường sẽ dựa vào lợi nhuận là hoa hồng của mỗi lần giao dịch nên phí cao cũng là điều dễ hiểu. Tùy cơ chế của mỗi sàn mà bạn phải trả các mức phí khác nhau. https://preview.redd.it/wttxu8qbcsx51.png?width=800&format=png&auto=webp&s=d685a048cf6487a3303436c9a4895965d5b7ab58 Remitano được biết đến là một trong những sàn tiền ảo uy tín
Mua tiền ảo bitcoin ở “chợ đen”
Bất cứ mặt hàng gì cũng sẽ có một thị trường “chợ đen” tương ứng và bitcoin cũng không nằm ngoài quy luật đó. “Chợ đen” là thuật ngữ được khá nhiều người biết đến tại thị trường tiền ảo Việt Nam, đây là hình thức mua bán trực tiếp giữa người mua và người bán hoặc thông qua trung gian. Hình thức giao dịch Bitcoin tại thị trường chợ đen có thể thực hiện online hoặc gặp trực tiếp, điều này có nghĩa bạn không mua bán trên các sàn giao dịch mà tự động tìm kiếm những người có nhu cầu để tiền hàng các giao dịch. Chợ đen có thể hoạt động trên Facebook, Telegram, Zalo,…và nhiều kênh mạng xã hội khác. Ưu điểm dễ nhận thấy nhất khi mua tiền ảo tại “chợ đen” là Không tốn phí giao dịch. Vì giao dịch được thực hiện trực tiếp nên bạn sẽ không phải chi trả bất kỳ phí giao dịch, hoặc nếu thông qua trung gian thì bạn cũng chỉ mất khoản phí nhỏ, chắc chắn sẽ không cao bằng phí của sàn. Khuyết điểm lớn nhất là sự uy tín và chất lượng. Vì hoạt động tự do, mọi giao dịch đều dựa trên lòng tin nên đôi khi bạn sẽ dễ gặp các rủi ro như bị “cuỗm” mất tiền.
Các điều kiện cần thiết để mua tiền ảo Bitcoin
Đặc thù của các giao dịch Bitcoin là không thể đảo ngược nên bạn phải rất cẩn thận với quy trình mua tiền ảo này. Dưới đây sẽ là các bước hướng dẫn giúp bạn mua bitcoin an toàn và hiệu quả nhất.
Tạo địa chỉ ví để lưu giữ Bitcoin
Bitcoin giống như tiền giấy bạn sử dụng hàng ngày, và chúng cũng cần được cất giữ trong một chiếc ví nhất định, mỗi ví sẽ cung cấp cho bạn một hoặc nhiều địa chỉ ví để lưu trữ Bitcoin. Địa chỉ ví có tính chất tương tự với một tài khoản ngân hàng giúp bạn có thể lưu trữ và chuyển tiền nếu muốn. Có 2 lựa chọn cơ bản để tạo ví Bitcoin: Ví riêng: Blockchain, Coinbase, Infinito Wallet, Jaxx, Exodus,.. Ví trên sàn giao dịch: Remitano, Fiahub, Binance, Bittrex, OKEx,.. Tùy theo mục đích mà bạn sẽ quyết định lựa chọn loại ví ở dạng nào. Nếu bạn mua Bitcoin với mục đích đầu tư lâu dài , không thường xuyên giao dịch, thì nên chọn ví riêng là tốt nhất. Ví riêng của Bitcoin thì bạn có khá nhiều sự lựa chọn, từ ví web online, ví phần mềm, ví mobile,… Còn nếu bạn thường xuyên giao dịch Bitcoin, hay muốn chơi trade coin thì nên nghĩ đến việc lưu trữ ngay trên ví của sàn để thuận tiện cho việc giao dịch. Việc chơi trade coin vẫn cần phải mua Btc bằng VND trên sàn Việt Nam rồi sau đó mới chuyển qua các sàn quốc tế để trade. Các sàn này thường cung cấp cho người dùng dạng ví của đồng coin mà nó hỗ trợ nên ví sàn có thể xem như một dạng ví tổng hợp của các đồng.
Đăng ký tài khoản trên cá nhân trên sàn giao dịch Bitcoin
Sau khi đã hoàn thành việc tạo ví Bitcoin thì tiếp đến bạn sẽ lựa chọn sàn giao dịch để đăng ký tài khoản, thực hiện các bước bảo mật, xác minh tài khoản trước khi mua hoặc bán Bitcoin. Nếu bạn đang có ý định mua tiền ảo bitcoin với số lượng lớn thì nên sử dụng sàn Remitano, còn mua Bitcoin nhỏ lẻ thì có thể thử nghiệm thêm sàn Finehub.
Hướng dẫn các bước mua tiền ảo bitcoin trên sàn Remitano
Bước 1: Lựa chọn hình thức mua tiền ảo bitcoin
Có 2 cách để mua tiền ảo. Cách 1 là mua Bitcoin nhanh thì bạn click vào “Mua Ngay“, mức giá này sẽ thay đổi tương ứng với tỷ giá Bitcoin thời gian thực. Cách 2 là bạn kéo xuống phần “Danh sách người bán” và chọn người bán mà bạn muốn. Nếu thấy mức giá hợp lý thì bạn chọn vào “Mua” bên phải. Tuy nhiên, bạn nên để ý mục “Tối đa” để biết được số lượng họ muốn bán, điều này sẽ giúp bạn chọn được người bạn phù hợp với nhu cầu mua của mình. https://preview.redd.it/iq0oudpccsx51.png?width=800&format=png&auto=webp&s=1fe7430a0cf75bd46bb22953fb6321e70a19272d Bạn có thể cân nhắc mua tiền ảo trên hệ thống sàn Remitano
Bước 2: Nhập thông tin mua Bitcoin
Các thông tin bạn cần nhập là số lượng BTC bạn muốn mua. Nhận Bitcoin vào “Ví Remitano của bạn” hay “Ví BTC cá nhân”. Hoặc nếu muốn chuyển vào ví Blockchain thì có thể nhập địa chỉ của ví blockchain đã tạo. Sau khi nhập số lượng BTC thì Remitano sẽ gợi ý cho bạn danh sách người bán đúng số lượng bạn muốn mua. Người trên cùng thường là người bán với mức giá rẻ nhất. Bạn nên cân nhắc chọn “người bán nhanh” và “qua Vietcombank” để tối ưu quy trình giao dịch. Các ngân hàng như Techcombank, ACB, Vietinbank, Agribank,…vẫn cho phép giao dịch nhưng sẽ rất phức tạp và mất thời gian. https://preview.redd.it/zygyzmddcsx51.png?width=800&format=png&auto=webp&s=47838f43647ec008c27960b27de7a5a57f5da2ee Remitano sẽ gợi ý cho bạn một số người bán phù hợp Sau khi chọn “Mua Ngay” thì Remitano sẽ thông báo để xác nhận bạn đã nhập đúng địa chỉ ví BTC cá nhân chưa. Vì có một vài trường hợp các hacker đã thay đổi địa chỉ ví của bạn khiến cho số lượng bitcoin không chuyển vào ví của bạn mà chuyển đi nơi khác. Tích vào 2 ô rồi chọn “Xác Nhận“ nếu thấy các thông tin đã chuẩn xác.
Bước 3: Đợi chờ giao dịch và kiếm tra ví bitcoin
Đến đây thì việc của bạn là chờ khoảng 15 – 20 phút để quá trình giao dịch diễn ra. Sau thời gian đó bạn sẽ kiểm tra lượng bitcoin mà mình mua đã được chuyển sang ví Blockchain hay ví sàn chưa.
Trên đây là nội dung thông tin hướng dẫn cách mua tiền ảo Bitcoin đơn giản và hiệu quả nhất. Bạn có thể thực hiện tương tự với các đồng coin khác chứ không nhất thiết cứ phải là bitcoin. Đối với những người mới bắt đầu mua lần đầu tiên thì nên chọn số lượng nhỏ để hạn chế đến mức thấp nhất những rủi ro có thể xảy đến.
