They have a pretty high score there. I would also like the OP to post there and see how justbit representative responds.
I don't like casinos that keep saying they don't require KYC for crypto users even though they know that's not really the case but I still feel like we're short on information here. OP already admitted he has been playing there for a while so they probably have enough data to investigate the account starting with a KYC. I hope we also get to see their side.
