- USDT
(1) What is USDT?
Tether USD (USDT) is a token launched by Tether Firm, based on a stable value currency — the US dollar. 1 USDT = 1 U.S.dollar. Users can buy USDT on the Exchanges such as RealBTC at any time with the legal currency in the country where they are located, exchange USDT for Bitcoin, and vice versa. Tether Firm strictly abides by the 1:1 cash reserve guarantee, that is, one USDT token once issues, Tether deposits 1 USD to its bank account as reserve guarantee.
USDT is a digital asset based on the Omni Layer protocol released on the Bitcoin blockchain. The biggest feature of USDT is that it is equivalent to the same amount of U.S.dollars. USDT is designed as a replica of the U.S.dollar on the digital network, making it a good value-preserving token in the volatile cryptocurrency market.
RealBTC supports USDT-standard perpetual contracts such as BTCUSDT-perp, ETHUSDT-perp, XRPUSDT-perp, LTCUSDT-perp, EOSUSDT-perp, BCHUSDT-perp, ETCUSDT-perp.
(2) Features
Intuitioanl: USDT is equivalent to the U.S.dollar, so it is used as the value measurement unit of cryptocurrency on many platforms.
Stable: Because USDT is backed by legal currency, users can continue to trade on the blockchain asset market without being affected by the price fluctuations of most blockchain assets.
Transparent: Tether Firm, the issuing company of USDT, claims that its legal currency storage account will be audited regularly to ensure that every USDT in circulation on the market has a corresponding US dollar as support. The storage account is public, and users can check it at any time. In addition, all USDT transaction records will be published on the public-chain.
Low transaction fees: There are no fees for transactions between Tether accounts or between wallets with USDT. However, a transaction service fee will be charged when converting USDT to the legal currency in the country where the user is located.

2. Bitcoin(BTC)
(1) What is bitcoin?
Bitcoin is currently the most widely used and recognized cryptocurrency. Born on 3rd Jan., 2009, bitcoin is a peer-to-peer digital encrypted currency with a total supply of 21 million. It is favored by technology enthusiasts due to its decentralization, global circulation, low transaction costs, and high anonymity. In recent years, traditional financial institutions on Wall Street and central banks from some nations have begun to study Bitcoin blockchain technology. Japan and Germany have already recognized the Bitcoin payment system.
(2) Advantages
Decentralized: There is no issuer and no possibility to manipulate the number of issues. Bitcoin is issued and circulated through an open source P2P algorithm.
Network robustness: Bitcoin relies entirely on a P2P network with no issuance center, so it is impossible for outsiders to crack it. While the price of Bitcoin may fluctuate, Bitcoin and Bitcoin’s vast P2P network will not go away. The number of CPUs and GPUs required to control 51% of the computing power of the Bitcoin network is astronomical.
Freedom of Payment: Any amount of bitcoin funds can be paid and received instantly anytime and anywhere. No bank holidays, no borders, and no restrictions imposed. Bitcoin allows its users to have complete control over their funds.
Extremely low fees: Users can include fees in their transactions to gain priority in processing and quickly receive confirmation of transactions from the network , resulting in much lower fees than PayPal or credit card networks.
Reduce the risk of merchants: Bitcoin transactions are safe and irrevocable, and do not contain personal information or sensitive information of users, which avoids the loss of merchants caused by fraud or fraudulent chargebacks.
High security and controllability: Bitcoin users have complete control over their transactions, and merchants cannot forcefully charge fees that they should not have. Bitcoin users can also protect their funds through backup and encryption.
Transparent and neutral: Everyone can examine bitcoin information in real time, but no one or organization can control or manipulate the bitcoin protocol because it is protected by encryption. This makes Bitcoin completely neutral and transparent as well as predictable.

3. Ethereum(ETH)
(1) What is ETH?
Ethereum is a next-generation cryptographic ledger that can support many advanced functions, including currency issue from users, smart protocols, decentralized transactions, and the establishment of centralized autonomous organizations (DAOs) or decentralized autonomous companies (DACs). Ethereum does not specifically support every single type of function as a feature. On the contrary, Ethereum includes a built-in Turing-complete scripting language that allows you to write the features you want to achieve through a mechanism called ‘contract’ Code. Technically, Ethereum is a digital currency open source platform and a blockchain platform. It provides developers with a platform for building and publishing applications on the blockchain. Ethereum can be used to program, decentralize, guarantee and trade anything.
On February 28, 2017, a group of transnational corporations from the oil and gas industry, financial industry and software development companies formally established the Enterprise Ethereum Alliance (EEA) to develop Ethereum into an enterprise-level blockchain. These companies include oil giant British Petroleum(BP), Morgan Chase, Microsoft, Accenture, Santander, BlockApps, BNY Mellon, Chicago Mercantile Exchange, ConsenSys, Intel and Nuco. Many companies or organizations develop projects based on the Ethereum blockchain and issue tokens. The United Nations World Food Program successfully used the Ethereum blockchain to provide assistance to 10,000 refugees.

4. Ripple(XRP)
(1)What is XRP?
XRP is an unimpeded global payment network based on blockchain technology. It is the world’s first open payment network. Users can use any currency to transfer money, including U.S.dollars, Euros, CNY, Yen and Bitcoin, Simple and fast. Transaction confirmation is completed within a few seconds, transaction cost is almost zero, and there are no inter-bank, remote or cross-border payment fees.
Since May 2017, Ripple’s validator network has expanded by 140%, with 55 participants including WolrdLink, Telindus-Proximus Group, Microsoft, MIT, CGI, Swedish ISP, Bahnhof, and data integration service provider AT TOKYO, etc. And all these participants are maintaining the integrity of this Ripple distributed ledger to help it ensure the consistency of transaction settlement orders.

5. Litecoin(LTC)
(1) What is LTC?
Litecoin was born on 7th October, 2011 and is called ‘Digital Silver’. Litecoin has the same implementation principle as Bitcoin technically. It is the first cryptocurrency based on the Scrypt algorithm. Compared with Bitcoin, Litecoin has faster transaction confirmation time, larger network transaction capacity and higher efficiency. Litecoin now has a complete industrial chain and sufficient liquidity, enough to prove that it is a mature, safe and stable commercial financial system.
(2) Chain
The Litecoin data blockchain can handle a larger transaction volume than its competitors, such as the Bitcoin data blockchain. As data blocks are produced more frequently, the network supports more transactions, and there is no need to modify the software in the future.
(3) Wallet encryption
Wallet encryption can ensure the security of the private key of the user’s wallet, so that the user can view the transaction status and account balance, and the user must enter a password before using Litecoin. This function can not only prevent the intrusion of viruses, but also a legal and effective check before the payment.
(4) Mining reward
The entire Litecoin network can process a block every 2.5 minutes, so it can provide faster transaction confirmation.
The entire Litecoin network is expected to produce 84 million Litecoins, which is 4 times the amount of currency of the Bitcoin network.
Litecoin uses the Scrypt cryptographic algorithm, first proposed by Colin Percival, in its proof-of-work (POW) algorithm.

6. EOS Token
(1) What is EOS?
EOS (enterprise operation system) is a brand new blockchain-based smart contract platform led by Block.one Firm, which aims to provide underlying blockchain platform services for high-performance distributed applications. The goal of the EOS project is to realize a blockchain architecture that supports distributed applications similar to an operating system. The architecture can provide accounts, identity authentication, databases, asynchronous communication, and program scheduling and parallel operations on tens of thousands of CPU/GPU clusters. EOS can eventually support the execution of millions of transactions per second, while ordinary users do not need to pay usage fees to execute smart contracts.
(2) Functions of EOS token
EOS token is currently an Ethereum-based token issued by the EOS blockchain infrastructure. It is mainly composed of three application scenarios: bandwidth and log storage(hard disk), calculation and calculation reserve (CPU), and state storage (RAM). After the EOS mainnet is launched, EOS tokens will be converted into tokens on the main chain. The specific explanation is:
Recipient payment: Customers purchase specific products from the business, and the sales revenue of these products will be used to pay for business costs, avoiding customers to directly pay for the use of blockchain, and will not restrict or prevent the company from determining the monetization of its products Strategy.
Authorization capability: If a blockchain is developed based on the EOS software system, and its tokens are held by a token holder, he may not need to consume all or part of the available bandwidth immediately. In this era, token holders You can choose to give or lease the unconsumed bandwidth to others.
Separate transaction costs and token value: If the application owner holds a corresponding amount of tokens, then the application can continue to run in a fixed state and bandwidth. Developers and users will not be affected by price fluctuations in the token market, so they are not dependent on price.
Block rewards: The upper limit of the rewards given by EOS to block producers is up to 5% per year, that is, the total annual increase in the new supply of tokens does not exceed 25%.

7. Bitcoin Cash(BCH)
(1) What is BCH?
Bitcoin Cash is a new version of Bitcoin with different configurations launched by a small group of Bitcoin developers. On 1st Aug. 2017, Bitcoin Cash started mining, and every Bitcoin investor’s account will have the same amount of Bitcoin Cash (BCH) as the number of BTC.
(2) Total Supply: 21 million
(3) Features
BCH has modified the Bitcoin code to support large blocks (increasing the block size to 8M), does not include the SegWit function, and is a blockchain asset generated by the BitcoinABC project.
The previous life of Bitcoin Cash was just Bitcoin. Before the fork, the data and software it stored in the blockchain was compatible with all Bitcoin nodes. After the fork, it began to execute new codes, Pack large blocks and form a new chain.

8. Ethereum Classic(ETC)
(1) What is ETC?
Ethereum Classic, whose function is very similar to that of Ethereum, is a forked currency that was hard-forked after the 1,920,000th blocks of ETH blcokchain.
The hard fork of the Ethereum blockchain in July 2016 aims to transfer The DAO’s funds stolen by hackers to an account controlled by investors, and to make old transaction records forgotten by history. So Ethereum Classic was born. Most Ethereum developers participated in this reversal, as did exchanges, startups, and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old transaction records. So a small group of miners continued to use the original blockchain as a form of protest, describing the hard fork as an act of spin-offs against The DAO — an abandoned project.
