The answer to your question dated back 9 months ago, where our team said that crypto accounts might be registered from Germany, is not actually the case at this moment. We do not accept German players anymore even Crypto.
I will repeat what I said earlier. If that is no longer the case, and you can't have German players on your casino, you can't just apply those rules to a period in time where those regulations weren't yet in place and you were in fact allowed to have players from Germany gambling with crypto. You are doing that currently with this player in question. The appropriate course of action would have been to inform those players who reside in restricted locations and tell them that they are no longer allowed to play on your casino for this and that reason. You didn't do that and went straight to confiscating funds.
Did you understand what LoyceV was trying to tell you? You are heading towards the direction of having Buff.bet being market a scam. Why throw away a decent reputation here for such a foolish act? The ball is in your court, do what you want with it.
