In my opinion there is really no difference between bank and USDT if they can freeze coins. So, I am just wondering, if you have any preferred stable coins which is safe and can't be frozen etc.ion
DAI was the only answer for your question but i have different opinion about that. I've been using USDT since it was getting introduced and im not feeling any problem with it. This backdoor used to prevent something like hacking fund. it has nothing to do to rob your profit from the market. that's why im not even feeling worry to keep my fund into the USDTI wish to convert some of the coins to stable coins for next bull run. So, your suggestions will be very much appreciated 
If you're feeling worry with USDT and just go for DAI but i think as long as you're doing good and you should not feel worry even to convert your money into the stable coin like USDT or something else
