Although stablecoins are currently very popular, if you think about trading in the secondary market, you're just a bag holder, similar to a scam (kind of like the Plus Token scheme, but with a license issued, the government prints money at zero cost). The market doesn't need that many stablecoins; having USDT is enough. Those creating stablecoins are just setting up a project to get you to hand over your money, then they take your principal, buy Bitcoin, and that's it. As the saying goes: 'If you want to make big money and get rich quickly, the other party wants your principal, all in on Bitcoin.'
