The two I've found for out of the box hosting that accept crypto
GTXgaming : Accept Bitcoin with the automated system, accept XMR with a human ticket, require voluntary KYC on account creation, but none of it verified other then a email check. The game panel services work well, but have a very much built in the 90s vibe to them.
AleForge : Accept a bunch of cryptos with a automated system (btc, xmr, etc), requires voluntary KYC on account creation, but only email verification. The game panel services feel much more modern, but lack some features that GTX has (being ancient has an advantage, like more seamless service upgrades).
These are the only ones I've found, after checking every factorio hosting service I could find listed that actually accepted crypto; I'd love to have more options going forward - especially with less friction.
