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.
add in that dai is also making a name next to usdt . both stable coins were being used the most by the people is because these two coins are first to became popular just like btc , btc gained momentum and stayed on top for a long time and eventually many people heard of it and stick with it compare to the cryptos that are new to them but its still up to them if they want to try something unusual they can always check the other kinds of stable coins .
