...DAI, I think DAI is not safe Can lose value 1 day.
So what is your suggestion?
DAI is your best option if you're are too worried about the centralization of other stable coins. I don't think there are better options to be honest. Maybe you should read more about CDP and MakerDAO so you have a better understanding on DAI's sustainability.
OP you raised an important and interesting question. USDT/C are both centralized and so there are issues with them both, however if SEC was to ban the use of these stable coins the whole crypto market will get hit hard since most pairs are tied to USDT. This will cause trouble with no matter what stable or crypto asset you hold.
As for options other than USDT/C, DAI is also an alternative but again comes with its own volatility. There are also other options which you'll need to look into but the others worth looking at are BUSD, and UST.
