Well I don't recommend you taking the risk and gambling again, because your luck will run out eventually and you will regret it, so you better quit while you are ahead, and holding what you have from bitcoin and waiting the price to increase is better and safer than throwing it into a casino, but if you insest on sticking to your idea I recommend casinos that have a wallet in them, ones where you can deposit and play, since the transaction time of bitcoin have increased and the fees got a bit higher having to wait for the transaction can make the gambling experience a bit frustrating especially if you lose.
It's better to stay away from gambling for now rather than go into the casinos, i will rather invest into the casinos if i was ahead this way no matter how small the amount is because he will eventually get burned with this mindset of not knowing when to play. It means he's not resolved yet and still don't know what to do and that can be fatal in the world of gambling.
