1. Titancoin, 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 TEDA Coin USDT is a virtual currency (crypto asset) that pegs digital currencies to the fiat currency, the US dollar, and is also a digital asset kept in a foreign exchange reserve account and backed by fiat currency. It is a digital currency with a relatively stable price, commonly known as a stablecoin. TEDA coin is a token based on the stable value currency US Dollar (USD), 1 USDT = 1 USD, and users can use USDT to exchange 1:1 with USD at any time. It strictly adheres to a 1:1 reserve guarantee, meaning that for every USDT token issued, $1 is deposited into its bank account as a capital guarantee. Users can check the funding details at any time on the Tether platform to ensure openness and transparency. (2) Three forms of USDT ①Omni-USDT: based on the Bitcoin network, the coin-filling address is a BTC address, and the coin-filling and withdrawing goes through the BTC network In November 2014, USDT was born on the Bitcoin network and officially went live on several major mainstream exchanges in February 2015. Until 2018, there was only one transfer path for USDT, and that was Omni-USDT based on the Bitcoin network. Omni-USDT is stored on a Bitcoin address, so every time you transfer money, you need to pay Bitcoin as a miner's fee. omni-USDT is on the chain of the Bitcoin network, and the cost of hacking is high, so the asset is relatively safe. However, its transaction speed is very slow and no longer meets the needs of today's crypto trading market, but many large transactions will still prefer Omni-USDT. ②ERC20-USDT: Based on the Ethernet ERC20 protocol, the coin-filling address is an ETH address, and the coin-filling and withdrawing goes through the ETH network In early 2018, the Ethernet network exploded in popularity, smart contracts became popular for blockchain applications and ERC20-USDT emerged. Like Omni-USDT, the use of ERC20-USDT also requires the payment of absenteeism fees, but the transfer speed has been significantly improved. Due to the security and speed of transfers, ERC20-USDT has been widely accepted by the market and TEDA, the issuer of USDT, has begun to abandon Bitcoin Omni in favour of the more efficient Ether ERC20. with TEDA having recently issued several additional USDTs on Ether, the number of ERC20-USDTs has increased significantly and now exceeds the total number of Omni-USDTs by 50% of the total. In addition to the official abandonment of the Omni protocol, mainstream exchanges have also started to shift to support ERC20-USDT. on July 3, the CoinExchange announced that it would switch from the OMNI network to the ERC20 network, and while USDT from the original OMNI network can continue to be topped up and credited, it will not be possible to withdraw USDT from the OMNI network. ③TRC20-USDT: based on the Wavefield TRC20 protocol, the coin-filling address is a TRON address, and the coin-filling and withdrawing goes to the TRON network In April 2019, TEDA announced the release of USDT based on the TRC-20 protocol on Wavefield, and TRC20-USDT was born. TRC20-USDT was released with the promise of full openness and transparency, zero transfer fees, and seconds to account. Unlike the previous two, there is currently no fee for TRC20-USDT transfers, which is a highlight of the Wavefield build. However, the development of TRC20-USDT is not very mature at the moment, and there is no guarantee of security. (3) USDT features (1) Stability: Tether converts cash into digital currency, anchoring or pegging the price of national currencies such as the US dollar, the euro and the Japanese yen. Since Tethers (USDT) is backed by a real-world currency store, it claims that users can enjoy the benefits of digital, blockchain-based transactions without the volatility of most cryptocurrencies. ② Transparency: Tether claims that its legal reserve account is regularly audited to confirm that its reserve account can actually support the value of Tethers (USDT) in circulation. Balances are updated regularly and can be accessed publicly at any time. All Tether transactions are recorded on a public blockchain. ③Blockchain technology: The tether platform is built on top of blockchain technology, taking advantage of the security and transparency they provide. ④Extensive integration: tethers are used on Bitfinex, shapUNK, GoCoin and other exchanges. ⑤ Security: Tether's blockchain technology provides world-class security while meeting international compliance standards and regulations. (4) USDT Advantages The biggest advantage of USDT is that it protects investors' assets in the cryptocurrency world from shrinking as the market rises and falls. It is equivalent to the same amount of US dollars, with 1 USDT = 1 US dollar, making it a good value preserving token in the highly volatile cryptocurrency market. The logic on which USDT is based is similar to that of Bitcoin - there is demand in the market and full market pricing. (5) Uses of USDT Firstly USDT should currently be available for digital payments as well as cross-border remittances and currency exchange. For example, with the BIYAPAY platform, all you need to do is provide your email account to the other party registered on the BIYAPAY platform and you can transfer money to the target in one click, with the money arriving in seconds. Secondly, the security of the transaction can be guaranteed to the greatest extent, as each transaction can be traced on the chain and cannot be tampered with at will, unlike traditional APP remittances or remittances between banks, where the bank's background data can be tampered with. Therefore, the security of USDT is very high. In addition, as an important tool for currency exchange, USDT can be an excellent tool for making profits with the US dollar due to its distinctive feature of being pegged to the US dollar, especially with the existence of platforms like BIYAPAY that can meet this demand, which provides a huge arena for the value of USDT to flourish. (6) Disadvantages of USDT The biggest risk with USDT is that Tether's issuance is completely centralised, meaning that the issuance, acceptance, regulatory risk and operational risk are all concentrated in Tether. Although Tether has pledged to reserve 100% of its USD reserves for USDT, this reserve is not completely open and transparent, and no one knows if Tether is misappropriating the reserve, over-issuing or abusing USDT.

2. 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. If you want to reduce your Binance trading fees, you must register using the invitation link below or use the invitation code "Q022W7SC". https://accounts.binance.com/en/register?ref=Q022W7SC

(2) Reducing OKX fees OKX is a professional digital currency trading platform loved by many users, and its transaction fees can be reduced. Depending on the volume of transactions, OKX divides its users into two levels: normal and professional. Ordinary users are graded according to their OKB positions, while professional users are graded according to their trading volume and asset size. The different tiers determine the trading fees for the next trading day. When calculating the fee levels, if the coin trading volume, total trading volume of delivery and perpetual contracts (USDT delivery contract, coin-based delivery contract, USDT perpetual contract, coin-based perpetual contract), option contract trading volume, and asset volume meet the conditions of different fee levels, users will enjoy the fee discount of the highest level.
