for now I still believe in using Tether (USDT), because in my opinion Tether (USDT) is the best stable coin at the moment and has the highest trading volume, so of course I believe if Tether (USDT) is still safer to use than other stable coin, then from that until now I still use Tether (USDT) for stable coin.
highest trading volume doesn't mean its best but at least its give assurance that you could alway liquidate your stablecoin anytime. not that the other have low trading volume, which means the other are just as good.
I think its more of how transparent the company behind them are in regard of their reserved money.
