If you have to use or keep stable coins I suggest decentralized stable coins like DAI but USDT is not bad at all it's just that I don't like anything centralized entity
well, DAI seems to be a good option, however they seem to have liquidity issues, meaning you could run into issues trying to exchange it back to other ALTs..
Despite all the bad news about USDT, we can see a daily trade volume in billion $ here..
