I'm not sure TBH. I do avoid USDT - I'm actually reducing my stake in 4Belt on Cub because that's one of the elements.
Also I'm lowering the amount of stables I was thinking of holding, I may as well just cash out instead.
I can't imagine the regulators will be able to touch the pure crypto stables - like UST for example - the one's that are supposed to be backed with fiat assets are going to be their targets I guess.
