Tether, also known as USDT, is a controversial cryptocurrency issued by Tether Limited, which is controlled by the owners of Bitfinex. USDT is a stablecoin. Issued in 2014, this coin is based on a blockchain-based platform that facilitates the use of fiat currencies through digital means. (1) What is brick arbitrage The difference between the price and the withdrawal fee is your profit. (2) The principle of brick arbitrage ①The usual way of operation is to buy a large amount of USDT coins with fiat currency, then use the USDT coins and exchange them for other digital currencies, such as bitcoin, ethereum, etc. through coin trading. How does the exchange of bitcoins for money work? First, you exchange your bitcoins for USDT coins via coin trading, then you sell your USDT coins for fiat coins via fiat trading. When you want to cash out, you sell the USDT to them and they give you fiat currency. When you want to buy USDT, they will sell you coins again, so back and forth, naturally, it is the profit of the difference. ② There are hundreds of digital currency exchanges that exist worldwide. The same USDT coin has a small difference in price on each exchange, such as a few cents, a few percent, etc. USDT merchants buy USDT on exchanges with low prices and sell USDT on exchanges with high prices, earning the difference. This way, both bear and bull markets are profitable and less risky. This less risky arbitrage operation is known as bricking in the cryptocurrency world. However, there is a fee for transferring USDT to each other. The more you transfer, the higher the fee. Therefore, the bricking method is not very popular nowadays. (3) Arbitrage method ① Wait for the right spread to appear. The actual money is used to calculate the fee, and it is profitable to move the bricks when the spread reaches a certain amount.

You don't know which side of the platform will be the low bidder next time the price difference appears, so you need to have USDT and BTC on both platforms beforehand, so that you can continue to move bricks when the price difference is larger next time.

The content introduced above is only about the basics of cryptocurrency, which is related to whether we can make money through cryptocurrency. Cryptocurrencies make money not only by scientific methods to increase income, but also by finding ways to save money. The handling fees are small, but they must not be ignored. I have calculated that with frequent transactions and long trading hours, the accumulation of fees can add up to more than 10,000 U a year. Next I will introduce a few common ways to reduce fees on large trading platforms. (1) Lowering Binance's fees Binance is currently the world's largest digital currency exchange, and you must sign up for Binance if you want to speculate on coins. The transaction fee is deducted from the assets received. For example, if you buy Ethereum/USDT, the fee is paid in Ethereum. If you sell Ethereum/USDT, the commission is paid in USDT. Example. You place an order for 10Ethereum at a price of USD3,452.55 per share. Transaction fee = 10Ethereum0.1% = 0.01Ethereum Or you place an order to sell 10Ethereum at 3,452.55 USDT per share. Transaction fee = (10Ethereum3,452.55USDT)*0.1% = 34.5255USDT What many people do not know is that the Binance transaction fee can also be reduced.

NFT, non-homogenized token, is a type of data unit on a digital ledger known as a blockchain, where each token can represent a unique digital profile that serves as an electronic authentication or certificate of ownership of a virtual good. Due to their non-fungible nature, non-homogenised tokens can represent digital assets such as paintings, artworks, sounds, videos, items in games or other forms of creative works. (1) Common NFT scam methods (1) Buying a pirated NFT collection When buying, you need to confirm that the NFT is from the correct collection item, which can be judged by the item's blue tick certification, number of issues, etc. ②Fake NFT websites If you are interested in investing in NFTs, you first need to find a place where you can buy and sell NFTs. When you search for trading sites on the internet, thousands of search results will appear on the webpage, but many of them are fake NFT trading sites. Sometimes it can be difficult to tell the difference between a scam site and a real one, as scammers are now making fake sites look like the real thing. There are no real or valuable NFTs on the scam sites, so if you buy NFTs on them you're just wasting your money. Worse still, scammers can record all the information you enter on the site. Usually you only need to provide the MetaMask wallet address to trade, but a scammer may ask you for your ethereum wallet helper (the master key to your cryptocurrency wallet) and use the information you provide to hack your wallet and steal all your crypto assets. Choose a legitimate NFT trading site The easiest way to stay safe is to choose a legitimate NFT trading site. There are many different types of NFT, sports, video games, virtual real estate and more. In addition to the best known NFT trading platform, OpenSea, a number of other legitimate NFT marketplaces/NFT collecting sites are listed below. Art NFT: Super Rare, Foundation, Nifty Gateway, Rarible, Zora, Mintable. Sports NFT: NBA Top Shot, Sorare. Gaming NFT: Axie Infinity, Street Fighter, Myth. Virtual Real Estate NFT: Decentraland. Twitter posting NFT: Valuables. ③Trading in different cryptocurrencies As a result of trading on the same exchange many times, people may get too used to trading in the same cryptocurrency (e.g. Ether on Opensea) and lose sight of the importance of the type of currency. Someone may see such an opportunity to quote in cryptocurrencies that look similar but have much different values, and may accidentally sell the item at a very low price. ④ Inexplicable private messages and winning messages However, it is not uncommon to receive personal messages from the NFT team or the developer of the project you are currently following, telling you that you have won a prize or that the NFT project you are following has started selling in advance. Remember, don't click on the link when you receive such a message, the biggest no-no is to link your wallet to the website they provide! Almost 99% of development teams state that they will not contact individuals privately to avoid people pretending to be them, and if they do have information, most of it can be found on official communities or forums. Runaway scams A runner scam is when a person or group of people initially release a set of NFT collectibles as a way to start a larger project that is planned to unfold over time by way of game components, merchandise or events. They then run off with the millions of dollars they have raised without completing any of the actions they have promised to do, such is a runaway scam. In many cases, the scam will happen overnight, but there are other times when it's a slow and steady process and you'll find the project gradually abandoned, no longer updated and little new progress made. The best way to avoid getting caught in a runaway scam is to do your research. Research the team behind the project and assess their long-term business plans. Follow the project on Twitter, Discord or other public forums, as NFT projects should have a fairly active community of investors if they are to have good liquidity or lasting artistic value. (6) NFT portfolio packs mixed with counterfeits When you want to buy more than two NFTs on Opensea, you may think of buying more than one NFT at a time in a bundle to save on the large amount of Gas fee you will have to spend on each transaction, but be careful, you may have fallen into the trap of someone who wants to save money by using a bundle. A very common combo pack scam is to bundle three or five NFTs into a group and sell them, but when you take the trouble to check, you can easily discover their secret. (7) Buying NFTs at too high a price This can lead to sellers temporarily changing their prices without the website being updated at the same time. Buyers who are in a hurry to buy without careful confirmation may accidentally purchase the item at a high price, for example, if the seller temporarily changes the price by one digit, although the website shows a price of 0.09, they may purchase the item at 0.9 at the time of transaction. (2) How can I prevent NFT from being stolen? ① Install the latest software system and anti-virus software ②After receiving any files or links, scan or upload files to Virus Total with anti-virus software ③Create a password with high security and use double authentication ④Use a cold wallet and verify wallet security settings ⑤If someone steals your NFT, use the DMCA to file a copyright complaint ⑥If you receive a request to create an NFT, first stop and think about it and ask yourself a few questions: is the request coming from an account in good standing or a newly created account, do they have any comments in their avatar.

A Bitcoin private key is a password made up of letters/numbers and encoded in a different format depending on the wallet used. The private key is used to make irreversible transactions that are chained together under a mathematical signature method and used as credentials. It can be represented as one of several different forms, usually as a series of randomly generated numbers and characters, and has multiple variations of combinations of numbers and characters that make it difficult to crack. (1) What is a private key A private key is the ultimate way of attributing and using absolute cryptographic assets. Whoever has the private key has dominion over the cryptocurrency assets under that address; conversely, without the private key, there is no access to any of the assets at that address. When a cryptocurrency address is generated, it is the private key that is generated first, and then the public key is derived. The public and private keys form a key pair that becomes a cryptocurrency address. The private key is a 64-bit hexadecimal string of upper and lower case letters and numbers generated by an encryption algorithm. However, due to its irregularity, it is very difficult to remember the private key. Especially if you have many addresses, remembering each private key accurately can be a struggle. As a result, some people have begun to explore how they can back up and remember private keys in a more convenient and human-readable way. (2) What is a mnemonic A mnemonic is an alternative representation of a plaintext private key, first proposed by the BIP39 proposal to help users remember and transcribe complex private keys. The main purpose of a mnemonic is to help you remember your private key, which has an irregular string, whereas a mnemonic has a certain pattern. Generally, mnemonics have the same function as private keys and should be kept in a safe place. These words are all taken from a fixed thesaurus and are generated in a certain order according to a certain algorithm, so there is no need to worry about an address being generated just by typing 12 words. (3) Why mnemonics are important In the real world, if you lose your wallet or have your bank card money cut off, there is still a possibility of recovery. But because of the decentralised and anonymous nature of blockchain, it is almost impossible to retrieve your wallet if you lose your private key. Having said all this, I just want to emphasise the importance of the private key. The private key is the only proof of your assets in the blockchain world, and those who have the private key own the assets on the corresponding address. (4) The advantages of mnemonics Helicones are not case-sensitive and are more common words, so they are much more convenient to use than private keys, which is why they have gradually become mainstream wallets in recent years. Another advantage of a mnemonic wallet is that a set of mnemonic words can generate N private keys, each of which can correspond to a coin. If you have 30 coins (BTC, ETH, LTC, EOS, etc.), you don't need to record a separate private key for each coin, you can just record a set of tokens and control all your assets. A wallet such as Bite will display both the key and the token to the user, but it's generally good to have a backup of the token. (5) How to keep your mnemonics safe ①Copy it on a piece of paper/book A more primitive method of storage is to copy the private key/keyword in a piece of paper or notebook, and then store the piece of paper/notebook in a safe place, such as a safe deposit box. But paper is not fire or moisture resistant and pets and children can cause a devastating blow. ② Presence on a hardware device In addition to this, private keys/helper notes can be stored on hardware devices that are not connected to the internet, such as USB sticks and various hardware wallets. However, storage media in general have a theoretical life span, and PIN codes are easily forgotten, batteries are damaged and leak, and strong electromagnetic fires are difficult to store for long periods of time in case of accidents. Engraving on stone or metal plates The PINs can be stored for a long time if they are engraved directly on a stone or a metal plate with a high melting point that is difficult to corrode (e.g. a Cobo gold box) (see various ancient human grottoes) and then stored in a safe. However, it is also not safe if the metal plate can be transferred away from the coin by someone with physical access to it. Therefore, it is recommended that a metal booster + custom password be used to generate a hidden HD wallet, and that you must have both the booster and the custom password to gain control of the hidden HD wallet. Some wallets currently support this security operation, such as Cobo Vault. As custom passwords can generally be complex and easily forgotten over time, it is recommended that they are stored in online password management software such as 1password and Lastpass, after all, digital assets will not be stolen if only the custom password is leaked; and the reliability of these security company cloud services is far greater than personal storage conditions. Alternatively, a small amount of assets can be stored as a sentinel wallet in a wallet generated using only the helper word. If the assets of the sentinel wallet are stolen, this means that the helper word is compromised and the assets in the hidden HD wallet need to be transferred urgently.

Mining here is not the same as what we normally know, going into a mining hole with a hoe and mining. Mining is the process by which users run specific algorithms with their graphics cards to interact with a fixed online "mining pool (server)" to obtain virtual currency. (1) The principle of mining Mining is the process by which maintenance nodes in the network assist in generating and confirming new blocks in order to obtain a certain amount of additional bitcoins. When a user posts a transaction to the Bitcoin network, someone needs to record and confirm the transaction, forming a new block and stringing it together in the blockchain. Who should do this in a distributed system where there is no trust between each other? The Bitcoin network uses "mining" to solve this problem. Currently, a block of no more than 1 MB in size is generated every 10 minutes or so (recording the contents of the verified transactions that took place during that 10-minute period), strung to the end of the longest chain, and the successful submitter of each block is rewarded by the system with 12.5 Bitcoins (which is used as the first transaction within the block, after a certain number of blocks) and a payment service fee that the user attaches to the transaction . Even if there are no user transactions, miners can generate their own legitimate blocks and receive a reward. The reward is initially 50 bitcoins per block, which is automatically halved every 210,000 blocks, i.e. over a period of 4 years, eventually stabilising the total number of bitcoins at 21 million. Bitcoin is therefore a deflationary currency. (2) Registering an account If you want to use a graphics card to "mine", you first need to have a goal - where to mine. There are currently many "mining pools" to choose from, including Bee, Fishpool, Starfire, Spider, Firecoin, UU, Unicorn, Frogpool and so on and so forth. Users can choose the appropriate "mining pool" according to their needs to "mine". Let's take the "Starfire Pool" as an example to explain mining. Step 1: Open the home page of Starfire Pools and click on the "Login/Register" option in the top right corner to register. Step 2: Enter your personal email account and preset password, then receive a verification code to confirm your registration. Thirdly, create a sub-account name. You can create more than one sub-account and set a name that is equivalent to your "foreman name" so that the "mining farm" knows which foreman is responsible for mining and on whose profile the results of his labour are recorded. If you have multiple miners mining with friends, additional sub-accounts may be set up as required to record the results of "each foreman's" work separately. The income from the sub-accounts will be transferred to your cloud wallet by default. Step 4: Click Confirm to complete the sub-account setup. (3) Download and set up mining software Some of the more famous algorithms currently available are nbminer and PhoenixMiner. If you do not intend to use a third party program for mining, you will need to download special algorithm software for mining. The first step is to download and install the "Easy Miner" software. Once you have downloaded the software, you will be taken to the installation screen. When the software is installed, you will be prompted for the "Lock Overclocking" option, which will allow you to automatically overclock your computer at boot time, which is very convenient (for efficient mining, you may want to use the four options: memory frequency control, fan speed control, GPU frequency control, and power control). and power control)." If you have not whitelisted/disabled Win10 antivirus or turned off the firewall before installing the software, you can do so when installing the software and the software will automatically do the same. The second step is to run Easy Miner and perform a simple setup. Once the installation is complete, you can enter the main interface of Easy Miner, where you can check the mining status or make advanced and overclocking settings. First select the miner's name (i.e. the machine's logo, you can customise it to suit your preferences, just make it easy to remember). Then select the currency, we are mining ETH (Ether Cube), so we will select ETH directly. Note that the wallet is the "foreman account" (the sub-account starting with sp_), which we set to sp_tingfeng, and if you fill in this account, the ETH mined by the miner will be counted in this account. But that's not all, at the bottom of the pools menu we need to click on "Pool Management" and check if the pool address is correct. You can see from the pool manager that the address we want to choose for "Starfire Mainland" is cn.sparkpool.com and the port number is 3333, which is exactly the same as the "China Mainland" server for "Starfire Pool". The server is identical to the "China Mainland" server of the "Starfire Pool". So when we want to mine on the Easy Miner pool, we can choose "Sparkpool". The kernel is the algorithm, there are two main types of nbminer and PhoenixMiner, unless you go deeper, you can just choose the nbminer recommended by the software. Thirdly, click on "Start Mining" to start your mining journey. By default, the program will start automatically when you turn it on, and the mining function will be enabled automatically when it starts, if you don't want this, you can cancel it in the "advanced settings".

Coin Smartchain (BSC) is a rising star in the blockchain protocol space, relying on low gas fees and lightning fast transactions to attract a large number of users. (1) What is blockchain Blockchain is a decentralised data ledger that is securely shared. Blockchain technology supports the sharing of data among a select group of participants. It allows the collection and sharing of transactional data from multiple sources, the ability to subdivide data into shared blocks linked together with unique identifiers in the form of cryptographic hashes, and the ability to ensure data integrity, eliminate data duplication and improve data security through a single source of information. (2) What is Coin Smart Chain The story begins in April 2019, when Coinan launched its own blockchain, the Coinan Chain, with the goal of creating a high-speed blockchain that can support a large number of transactions. In order to achieve this goal, the team at Cryptocurrency Chain chose not to support multiple applications and to focus only on its main application - Binance DEX. At the same time, decentralised finance on Ether was booming, and Coin On realised that, like Ether, it needed to have smart contract functionality in order to keep up with the industry. Smart contracts are automatically executed by code snippets as soon as a set of predefined conditions are met. This lays the foundation for lending and other decentralised financial activities. Back to Cryptocurrency. At this point, they decided to launch the Coin On Smart Chain (BSC) instead of adding all these features directly to the Coin On chain, which could have caused the network to go down. The goal of the Coin On blockchain was always to rival Ether. (3) Differences between the Coin On Smart Chain and Blockchain Having realised the importance of time in building a cost effective alternative to Ether, Coin On started to radically reduce the time consuming task of building its smart contracts and adopted its own PoA (Proof of Authority) protocol. In fact, the CoinA smartchain even uses a special PoA consensus algorithm: proof of authority based on equity (PoSA). Under this special protocol, only 21 verifiers can confirm a transaction at any given time. Conversely, this makes the Cryptocurrency Smartchain more centralised than other platforms. Interestingly, the Cryptocurrency Smartchain makes its platform compatible with Ether. That is, it can run applications and execute smart contracts using the Ether model, but charges users far less in gas fees than Ether. As a centralised network, the Coinan Smartchain offers a much needed and affordable alternative to Ether, with the added advantage of faster transactions. The Cryptocurrency network is managed by the Cryptocurrency token "BNB", for which users pay network fees. Currently, each BNB is worth less than $400, so you can imagine the market adoption rate. (4) Advantages of the Cryptocurrency Smartchain With a range of advantages that appeal to users, including extremely fast operation, low transaction fees (as low as 1c), decentralised application creation and a network of millions of users, many people do choose the Cryptocurrency Smartchain. In addition, the Cryptocurrency Smartchain is the foundation for PancakeSwap, the main decentralised exchange on the Cryptocurrency network and one of the highest rated decentralised exchanges in decentralised finance. The Cryptocurrency Smartchain offers a practical solution for users less familiar with decentralised finance or those looking for a more affordable option than Ether. This is not to say that cryptocurrency enthusiasts are going in the wrong direction in the world of blockchain. On the contrary, the Coin Smartchain is indeed a reliable ecosystem, and the statistics alone prove its usage scenario.

Interstellar File System is a network transport protocol designed to enable distributed storage, sharing and persistence of files. It is a peer-to-peer hypermedia distribution protocol with addressable content. The nodes in an IPFS network constitute a distributed file system. It is an open source project that has been developed since 2014 by Protocol Labs with the help of the open source community. It was originally designed by Juan Benet. (1) IPFS principles Born in 2015, the IPFS protocol is an underlying protocol for the Internet that makes architectural innovations in two main areas: file transfer and data storage. For example, if you want to save a video on the IPFS system, the system will break the file into a number of uniformly sized fragments. These fragments are then hashed to get a value, the hash value. The hash value of all these fragments and the associated data are then collated and hashed again to get the final hash value, which is finally transferred to the IPFS system. During this process, it is likely that one of the fragments of your video is stored on your neighbour's hard drive, but he has no way of knowing the contents of the fragment and who stored the file for. Without a corresponding hash value, no one or institution can view your video, solving the problem that user data can be used by others. In addition, each shard is backed up multiple times and kept on multiple nodes of IPFS, so that even if one node suffers a server attack or hard drive corruption, the other nodes still maintain the integrity of the files. As for file transfers, when a user accesses or downloads a file using IPFS, the user submits the hash of the file to the system and, as each shard is only 256kb, as long as the file is stored throughout the IPFS system, the system can automatically identify the nearest node to transfer the contents of the shard at the same time, resulting in an amazing transfer speed. As file retrieval in IPFS is based on the hash of the file, to ensure user privacy, users need to encrypt the file before uploading it, so that in the future, even if a third party obtains the file hash, they will not be able to see the original content after downloading it. IPFS does not require every node to store all the content, and node owners are free to choose the data they want to maintain, after backing up their data, and voluntarily serve other content of interest in addition to their own. As an incentive to contribute storage and data retrieval services, in August 2017, filecoin, the incentive layer of IPFS, was publicly crowdfunded, raising $257 million in a very short period of time, creating an ICO miracle that year. If IPFS can be popularized and the number of nodes reaches a certain scale, even if each node only stores a little bit of content, the accumulated space, bandwidth and reliability will exceed h#IPFS#ttp the mode of transmission with a central server. (2) The content of IPFS IPFS is a protocol, similar to the http protocol -defines a content-based addressing file system -Content distribution -Technologies used distributed hashing, p2p transfers, version management systems IPFS is a file system -Has folders and files -Mountable file system IPFS is a web protocol -Internet pages can be viewed like http -Future browsers can directly support the ipfs:/ or fs:/ protocol IPFS is a modular protocol -Connection layer: connects via any other network protocol -Routing layer: finding and locating files -Data block exchange: using BitTorrent technology IPFS is a p2p system -Worldwide p2p file transfer network -Distributed network architecture -No single point of failure problem IPFS is inherently a CDN -Files added to the IPFS network will be accelerated on CDNs around the world -Bandwidth management for bittorrent IPFS has naming services -IPNS: based on the SFS (Self Authenticating System) naming system -Can be tied to existing Domain Name System (3) Features of IPFS The IPFS protocol allows any resource stored in the system, including text, images, sound, video, and website code, to be hashed by IPFS to generate a unique address. With the protection of encryption algorithms, this address is tamper-proof and cannot be deleted. This means that once the data is stored in IPFS, it will be permanent. For example, when you open some web pages, you sometimes get a "404 Not Found". The root cause of this is a problem with the central server you are browsing on, which is a problem caused by the centralisation technology and is difficult to change. This is a problem with centralised technology and is difficult to change. This does not happen with IPFS. Even if the central server is removed, the web page can be accessed normally as long as the network storing the information still exists. The more distributed networks that store a site, the more reliable it becomes. Secondly, it solves the problem of 'over-redundancy'. Today we all store files such as movies, music and electronic documents on our PCs. For example, my computer has downloaded my favourite movie Avatar, but maybe your neighbour also has it in his computer collection.　The consequence of this is a huge waste of memory resources, which is the downside of the HTTP protocol. The same resources are backed up too many times, creating the problem of over-redundancy. IPFS solves this problem by taking the stored files and hashing them once, so that only two files have the same hash value. The user only needs to use the same hash value to access that file, which is the address of the file. Once this address is obtained, the resource can be shared. Thanks to the perpetual storage feature of the IPFS protocol, you no longer have to worry about finding your favourite Avatar movie, you no longer have to back it up, because you can watch it forever on just a few computers around the world that have it stored, which saves a very large amount of memory resources.

The content introduced above is only about the basics of cryptocurrency, which is related to whether we can make money through cryptocurrency. Cryptocurrencies make money not only by scientific methods to increase income, but also by finding ways to save money. The handling fees are small, but they must not be ignored. I have calculated that with frequent transactions and long trading hours, the accumulation of fees can add up to more than 10,000 U a year. Next I will introduce a few common ways to reduce fees on large trading platforms. (1) Lowering Binance's fees Binance is currently the world's largest digital currency exchange, and you must sign up for Binance if you want to speculate on coins. The transaction fee is deducted from the assets received. For example, if you buy Ethereum/USDT, the fee is paid in Ethereum. If you sell Ethereum/USDT, the commission is paid in USDT. Example. You place an order for 10Ethereum at a price of USD3,452.55 per share. Transaction fee = 10Ethereum0.1% = 0.01Ethereum Or you place an order to sell 10Ethereum at 3,452.55 USDT per share. Transaction fee = (10Ethereum3,452.55USDT)*0.1% = 34.5255USDT What many people do not know is that the Binance transaction fee can also be reduced.

Bitcoin is a cryptocurrency based on decentralization, using a peer-to-peer network with consensus initiative, open source, and a blockchain as the underlying technology. Bitcoin was published as a paper by Satoshi Nakamoto on October 31, 2008, and the Genesis block was born on January 3, 2009. In some countries, central banks, government agencies and academics regard Bitcoin as a virtual commodity and not as a currency.

Grayscale Bitcoin Trust, or GBTC for short, is Grayscale's largest investment vehicle. Founded in 2013 by Digital Currency Group and headquartered in New York, USA, Grayscale is a trusted authority on digital currency investments. and is registered with the US Securities and Exchange Commission (SEC) with total greyscale bitcoin trust assets of $7,619 million as of 9 November 2020. At this stage, when the Bitcoin ETF is still not approved by the SEC, it is a compliant way to passively invest in Bitcoin, where customers can purchase a number of GBTC shares from Grayscale in cash or Bitcoin and trade them on the traditional OTCQX marketplace. (1) How GBTC works Although GBTC can be traded like a stock, it is not a stock, but a trust. The principle of its operation is easy to understand: Grayscale invites investors to inject money into the fund, then buys a large amount of bitcoin, and then the fund is listed on an exchange, allowing investors to buy and sell shares of the trust publicly. At the time of its initial listing, GBTC's share price was just US$0.54, and has now risen to US$44.35 as the value of the bitcoin has risen. GBTC tracks the value of the bitcoin on the CoinDesk Bitcoin Price Index (XBX), but does not follow the index as closely as mainstream passive ETFs, and often has a spread. Based on historical trends, GBTC has been trading at a premium most of the time, but has become a negative premium since early 2021. For example, on 5 May 2021, the Grayscale website showed that each share of GBTC was equivalent to 0.000943688 bitcoins, which suggests that GBTC should be worth around US$50 per share, but the actual market value at the time of market close was only US$46, representing a negative premium of around 10%. (2) What is Grayscale It is the first private equity fund dedicated to investing in Bitcoin. People can buy and sell bitcoins without having to learn anything about bitcoin, without having to create a cryptocurrency wallet, without having to go to a bitcoin exchange to buy bitcoins, without having to worry about bitcoins being stolen, without having to worry about losing bitcoins in poor private storage. (3) How Bitcoin becomes GBTC Raising. Setting up a bitcoin trust and raising money is the first thing Grayscale does. The first collection was made over 7 years ago, on September 25, 2013. According to US law, only institutional and qualified investors, can buy into Grayscale's Bitcoin Trust. So-called qualified investors are, frankly, wealthy enough people who are officially considered to have a high risk tolerance. Funding. Eligible investors can contribute in cash, or in bitcoin. With Bitcoin, 1 Bitcoin is exchanged for 1,000 GBTC, which means 1 GBTC = 0.001 Bitcoin. For a cash contribution, the same applies, converting 0.001 bitcoins to cash to calculate the number of GBTC shares a client can receive. Lock-in. Under US law, customers have a 12-month lock-in period after purchasing this fund. Later, through the tireless efforts of Grayscale, on 21 January 2020, Grayscale became an SEC reporting company and the lock-in period was changed from 12 months to 6 months. However, even after the lock-up period, customers still cannot redeem. Liquidation. Getting qualified investors to exit smoothly so that more people can can buy GBTC is the most important and crucial thing. Eventually, Greyscale found a 'shortcut' through FINRA approval and in March 2015, qualified GBTC was made available for trading in the 'over-the-counter secondary market', allowing qualified investors to exit satisfactorily and smoothly. On 4 May 2015, US shareholders began to be able to purchase GBTC. grey GBTC's value, for qualified investors, is liquidity. However, the greater value is that ordinary people can henceforth trade GBTC as if it were a stock. Because, there is a link between this secondary market and the traditional stock market, with a stock account comes the opportunity to buy and sell GBTC. (4) Advantages of GBTC -Easy trading GBTC can be traded through a general securities account, which is easy to operate and more familiar to the general traditional investor than a cryptocurrency exchange. It is also generally easier and cheaper to withdraw funds from a securities house than from a cryptocurrency exchange. -Simple storage There is no need to learn how to manage a cryptocurrency e-wallet and there is no need to worry about any risk of losing your private key or having your wallet hacked. -Safe and Secure GBTC is a listed trust and is regulated by the SEC, making it highly reliable. (5) Disadvantages of GBTC -Expensive management fees GBTC has an annual management fee of 2%, which is much more expensive than a typical US stock ETF. However, as the first Bitcoin ETF will not be available in the US stock market until October 2021, US stock investors have had no choice but to use GBTC as their main alternative in the past. -The premium issue GBTC often commanded a premium of 20% to 30% in 2020, reflecting investors' willingness to buy the trust at a higher price, but since the launch of the three Canadian Bitcoin ETFs, they have taken away much of the demand for GBTC, resulting in a negative premium for GBTC from February 2021 onwards, indicating a decline in demand and compromising Grayscale's ability to continue buying Bitcoin, with knock-on effects could affect the uptrend of Bitcoin and GBTC. -Unable to trade 24 hours a day One of the features of cryptocurrencies is that they can be traded 24 hours a day. GBTC is listed on a stock exchange and is naturally restricted to traditional stock market trading hours, so investors may not be able to take advantage of the best time to buy or sell.

A delivery contract is a futures contract in which both parties agree to buy and sell the contract at the price of the futures at a specified time, also known as the delivery date. The contract is a digital currency contract with USDT as the unit of denomination and settlement for regular delivery. The price of the contract is entirely formed by the market mechanism and does not use an index but the latest transaction price to calculate profit and loss. (1) What is a delivery contract? A delivery contract is a digital currency contract in which USDT is the unit of account and settlement, and delivery takes place on a regular basis. The price of the contract is entirely formed by market mechanisms, and the latest traded price is used to calculate profit and loss instead of using an index. Some people may ask why the USDT is used as the unit of account and settlement, is there any benefit? Of course there is. As Gua said, to play with delivery contracts, you don't need to hold other digital currencies, just USDT to trade delivery contracts of multiple currencies such as BTC and EOS, basically saying goodbye to the loss in the process of multi-currency conversion. Moreover, among digital currencies, USDT has a relatively stable long-term performance, so using USDT as the unit of denomination and settlement can reduce the risk of holding BTC, EOS and other digital currencies due to their own devaluation, and avoid the situation where the amount of coins increases but the assets decline. (2) Difference between delivery contracts and perpetual contracts ①Expiry date: The biggest difference between the two is that there is no delivery date for perpetual contracts, in theory, as long as the contract does not explode, it can always be held; while each delivery contract has a fixed expiry date, the delivery price is the arithmetic average of the dollar index of the latest hour of BTC (LTC and other currencies) as the delivery price for all open positions of the current week, the current quarter and other expiring contracts for delivery and closing of positions. ②Funding costs: Since perpetual contracts do not have an expiry date for delivery, a "funding cost mechanism" is required to anchor the contract price to the spot price. (3) Price setting: The perpetual contract is set against the spot price and the marker price is used to calculate the user's unrealised profit and loss, effectively reducing unnecessary and frequent position blowouts during market fluctuations. (3) Delivery contract play ①Fund transfer First of all, you need to transfer a certain amount of USDT to your delivery contract account, you can do so from various accounts such as top-up and withdrawal accounts, OTC accounts, etc. At this time, you already have USDT in your delivery contract account. ②Fund allocation Then is the allocation of funds, due to the delivery contract using position-by-position margin mode, if you plan to do a certain currency contract, you need to transfer the funds in the delivery contract account to the corresponding currency sub-account in advance, the following chart is the plan to do BTC will be transferred to the sub account of BTC USDT. ③Opening a position Once you have finished allocating funds, you can open a position. There are currently 9 contract types supported by the delivery contract: BTC, EOS, ETH, XRP, LTC, ETC, TRX, BNB, HT. As shown in the picture, you can choose the contract type you want to trade in the red boxed area on the left to open a position. In the red box on the bottom right, enter "Leverage", "Price", "Position (lot size)" and click on "Open Long " or "Open Short", at which point you have successfully submitted a buy or sell order. If the order is not filled immediately, you can see the order details in the "Current Orders" section of the "Assets" section; if it is filled immediately, the position is successfully opened and you can view the transaction details in the "Filled" section. In addition, you can view the current position's "average position price", "occupied margin" and "unrealised profit/loss" in the "Position" section. In addition, you can view the "average price", "occupied margin" and "unrealised profit/loss" of your current position in "Position", and support "Stop Loss" and "Take Profit" operations. ④Closing a position When you want to close a position, go to the asset area and click on "Position", you can choose to close a single position or "One Click Close", and the realized profit and loss from the closed position will have to wait for the settlement You will need to wait for the profit and loss to be settled before you can transfer it out of your current account.

Perpetual contracts are an "innovative" futures contract, pioneered by BitMEX. Traditional contracts have an expiry date, while perpetual contracts have no delivery date and can be held forever, hence the name Perpetual Contract. (1) What is a Perpetual Contract A Perpetual Contract is an innovative financial derivative that builds on, but differs from, a delivery contract. A perpetual contract is similar to a covered asset market in that it is priced close to the price of the underlying reference index and there is no concept of an expiry date. As long as the contract does not blow up, you can hold it for as long as you want. (2) What is a delivery contract A delivery contract is a futures contract where both parties agree to buy and sell the contract at the price of the futures at a specified time, i.e. the delivery date. The contract is a digital currency contract with USDT as the unit of denomination and settlement and is delivered at regular intervals. The price of the contract is entirely formed by the market mechanism and the latest transaction price is used to calculate profit and loss instead of using an index. (3) The difference between perpetual contracts and delivery contracts ①Expiry date: The biggest difference between the two is that there is no delivery date for perpetual contracts, in theory, as long as the contract does not explode, it can always be held; while each delivery contract has a fixed expiry date, the delivery price is the arithmetic average of the latest hourly BTC (LTC and other currencies) dollar index as the delivery price for all open positions of the current week, the current quarter and other expiring contracts for delivery and closing of positions. ②Funding costs: Since perpetual contracts do not have an expiry date for delivery, a "funding cost mechanism" is required to anchor the contract price to the spot price.

A perpetual contract is an "innovative" futures contract, pioneered by BitMEX. Traditional contracts have an expiration date, while perpetual contracts do not have a delivery date and can be held forever, so they are called perpetual contracts. (1) What is a perpetual contract? A perpetual contract is an innovative financial derivative that is based on a delivery contract, but has many differences from the previous one. A perpetual contract is similar to a secured asset market in that its price is close to the price of the underlying reference index and there is no concept of an expiration date. As long as the contract does not explode, you can always hold it. (2) The capital rate of perpetual contracts No delivery date means that the price of the perpetual contract is not a mandatory constraint, multiple parties and short parties are free to agree on a very outrageous price to do counterparty, so it is easy to become a gambling tool. In order to avoid this situation, perpetual contracts introduce the concept of a spot price index, and through the corresponding mechanism, the price of the perpetual contract returns to the spot index price. For example, the bitcoin perpetual contracts on some exchanges have the following provisions. (i) At a certain point, when the futures price is greater than and significantly deviates from the spot price, the long side needs to pay the short side. ② At a certain point, when the futures price is less than and significantly deviates from the spot price, the short side needs to pay the long side. The greater the deviation, the higher the rate of payment. (3) Trading fees for perpetual contracts The phenomenon of liquidation, due to rapid changes in the market, the investor did not have time to call the margin, the margin on the account is not enough to maintain the original contract held this insufficient margin and forced to close the position caused by the margin "to zero", commonly known as "liquidation ". Investors who encounter a "blowout", you will lose a lot of money. (4) perpetual contracts burst burst phenomenon, due to rapid changes in the market, the investor did not have time to call the margin, the margin on the account is not enough to maintain the original contract held this insufficient margin and forced to close the position caused by the margin "to zero", commonly known as "burst position ". If the investor encounters "burst", it will lose a lot of money. (5) Margin for perpetual contracts ①Full position margin Full margin refers to the use of all available balances in the account as margin to avoid the forced closing of positions. Any other position that has made a profit can help increase the margin on a losing position. The full position margin will include the margin of the position from which the full position was taken and the available, using the full position mode, the available under the user's full position loss will not be used as the margin of other full positions. ② Position-by-position margin The maximum loss on a position-by-position basis is limited to the starting margin and margin call used for the position. If a position is forcibly closed, the user will only lose position-by-position margin and the available balance of the account will not be called. By segregating the margin used for a position, the user can limit losses on that position to the starting guaranteed amount, thus helping you in case your short-term speculative trading strategy fails. Users can manually call margin into position-by-position to optimize the strong closing price. After a position is margin called, if the user adjusts the leverage, the previous margin call will be reset. (6) Automatic position reduction for perpetual contracts Automatic position reduction is a way for counterparties to force a position to close. Automatic position reduction occurs only when the PPF fails (a specific situation arises). Although the probability of occurrence is extremely low, such events require profitable traders to put up a portion of their gains to cover the losses of losing traders. Unfortunately, the digital currency market is highly volatile and the high leverage offered by perpetual contracts makes automatic position reduction impossible to completely avoid. In other words, counterparty forced close-out is the ultimate solution in the event that the PPF is unable to cover all zeroed-out positions. Typically, the positions with the highest profits (and leverage) also contribute the largest percentage of the automatic position reduction.

The content introduced above is only about the basics of cryptocurrency, which is related to whether we can make money through cryptocurrency. Cryptocurrencies make money not only by scientific methods to increase income, but also by finding ways to save money. The handling fees are small, but they must not be ignored. I have calculated that with frequent transactions and long trading hours, the accumulation of fees can add up to more than 10,000 U a year. Next I will introduce a few common ways to reduce fees on large trading platforms. (1) Lowering Binance's fees Binance is currently the world's largest digital currency exchange, and you must sign up for Binance if you want to speculate on coins. The transaction fee is deducted from the assets received. For example, if you buy Ethereum/USDT, the fee is paid in Ethereum. If you sell Ethereum/USDT, the commission is paid in USDT. Example. You place an order for 10Ethereum at a price of USD3,452.55 per share. Transaction fee = 10Ethereum0.1% = 0.01Ethereum Or you place an order to sell 10Ethereum at 3,452.55 USDT per share. Transaction fee = (10Ethereum3,452.55USDT)*0.1% = 34.5255USDT What many people do not know is that the Binance transaction fee can also be reduced.
