The problem is the promise, bitcoin and other "nonstable" crypto don't promise a fixed dollar value, similar to gold if you will. But if a crypto claims that it has a fixed currency value, then like banks (which they also say they have a fixed dollar reserve) it has to be regulated by the issuer of that currency. I don't see any problem in regulating stable coin.
