Now they banned all unapproved stablecoin, like USDT and DAI that doesn't meet their random requirements. USDC got the green light somehow, they were forced to store a part of the USF reserve in EU and show audit of proof of reserve.

DAI is backed by overcollateriazed ETH and their approved USDC and 100% on-chain verifiable but nah, that's not good enough for them. Seams quite random, unconsistant rules.

So who knows what they will come out for Bitcoin.
