Although BCH.games support Bitcoin deposits, but they don't support the withdrawal in BTC. The situation is similar to the BK8 casino. I remember, I had suggested about the
BK8 casino here, but OP hasn't added them in the list as they don't allow to make withdrawal in BTC. This table only contains the withdrawal information of Bitcoin. Perhaps, BCH.games won't be added in the list unless they implement Bitcoin withdrawal system.
How can they accept Bitcoin deposits and don't allow withdrawing the same coin you deposited?

This looks very sketchy if they are forcing you to withdraw in some other coin that is probably BCH, so is there a way to convert coins inside casino or what?
If I deposit 1 BTC in BCH.games, place a bet and win 0.25 BTC I should be able to withdraw 1.25 BTC, not some other altcoin.
Yes that is correct. All deposits at BCH.games casino are automatically converted to BCH using third party instant crypto exchange. The only currency available for withdrawal is, of course, BCH shitcoin.
It's a shame that such casinos are even allowed on this board, and if it were up to me, I wouldn't allow it.
