USDT, TUSD, BUSD, and USDC are all stablecoins. They have a value that is tied with the US dollar at 1:1 ratio. Now I'm wondering what is their differences.
- Does each of them has different purpose other than being tied to USD?
- Do they have different features or the fees when using them is different from one another?
- Why USDT is commonly used when trading other crypto not the others?
All are stable coins and each of them created by different people and running on different chains for the same reason. If you wanted to find the real difference then you should added DAI into it which is also a stable coin and it is decentralized which is the big difference with those stable coins you mentioned.
