Also re: dirty coins, as long as a way to swap them back to xmr exists, I think I should be ok. I think we won't find ourselves in a future where dirty coins are rejected even by individuals without there being plenty of writing on the walls that btc is dead so hopefully I'll be able to pull out before then.

Privacy features on btc like lightning are quite useful for enabling this kind of thing, plebs atomic swap dirty btc to whales with the kind of liquidity required to clean it in exchange for xmr at a comparably minimal markup. Works beautifully tbh.
