>Monero could of helped, although its not easy to transfer BTC to Monero without P2P
It's really not hard but it probably gets much harder to transfer tainted Bitcoin. Trocador.app aggregates various no-KYC CEX swaps and is regarded well in the Monero community.
As we can see from the various Monero pumps, which often stemmed from cleaning coins. Thieves don't want to sit on the Bitcoin so they drive up the price of Monero selling it fast.
Yeah P2P is more technical. Hopefully with Serai we can get a good UX decentralized exchange.
Swapping into fiat is a different beast.
