Hi, I'm a normie who finally got into crypto in nov 2021. But I don't get stable coins. When you sell your crypto, why don't you just convert back to fiat and put that fiat into your bank account right away? I worry about stable coins becoming un-pegged; this is a big concern for me; it's an extra worry that you don't have if you just convert back to fiat right away.
If you are a trader, you would buy and sell many times. So it will not be suitable that every time you sell your crypto, you withdraw it straight into your bank. Then again if you want to trade, you will again convert fiat to crypto and incur all these extra costs. For this reason, stable coins are important.
