When they exist, there is nothing wrong with them at all. What fears me is the moment they may not exist anymore, that will definitely be not that easy at all. Remember, we are talking about USDT type of stuff with 100+ billion dollars, and that means we are going to end up with some stuff that may cause a lot of trouble for us. Imagine a 100+ billion dollar marketcap USDT crashing suddenly, after all its backed by just one company and anything could happen, if that happens then we are going to end up with a lot of trouble and it should not be all that easy at all. We should consider some other stuff in that case.
