Swap to XMR on a DEX, then juggle between a few wallets and you've got pretty good obfuscation, but yeah like you said, the off-ramp (FIAT) requires KYC in 99% of cases, which is why BTC -> XMR -> BTC is a good idea, obviously you'd fragment this through a LOT of wallets, or just keep it in XMR. Either way, keeping this type of money in crypto is pretty much your only option, you just need to obfuscate REALLY well.
