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.
I made a complaint on casino.guru. I also asked justbit to give me proof of any wrongdoing because they stated that they can ask for documents if they suspect anything. I didn't ask for any bonus, or had other accounts in the past on justbit. You guys have to understand that I do not play regularly and deposited just for that "No KYC" promise...
