I don't use centralized exchanges. Haven't done so for the last 5+ year. Fortunately you can still exchange EUR 1k per transaction with no KYC here. Used to be 10k, now it's 1k, so the noose is tightening, but it's going to be very hard for them to lower this limit, as this would have to come with fiat currency withdrawal limits at ATMs and all that.
Anyway, the system can be "cheated" as the limits aren't per day, but per transaction, so it only makes things annoying, but not impossible to accomplish

As for the US, they're obviously trying to attack bitcoin by making the public think that it's used by terrorists, and since there's a war in Palestine and Palestinians are being labeled as terrorists, it all makes sense. There's always going to be the right side of the conflict. The side that pays more, that can offer more if it wins, and so on.
This is just a proposal and there were many similar proposals in the past that did not get approved, so time will tell how this goes.
