There're so many stable coins nowadays but Tether is still of the most used of them. Even though there were a lot of bad news about USDT, and I doubt that it's really backed up by dollars at 1:1 ratio, but I still use it very often in my daily trading. Of course it's always good to have diversification even among stable coins, but I don't think that Tether can become SCAM on day. I could have such a huge impact on the market, that it's even hard to imagine.
