I also stop when bitcoin fees high, but now a days, bitcoin price down then it is easy for us to play with bitcoin. But now in the coming time i think bitcoin once again will increase a lot of then it will be trouble for us.
Do not gamble with btc or altcoins now as the market have recovered well in few days and seems to be recover more in coming days. So if you happen to lose some games it means you will lose out the opportunity of holding your coins and making some gains as the price continues to rise.
If you just buy then gamble then withdraw and convert the coins back to fiat then there is really no problem. Think of it like you are in a real casino where you trade your fiat for chips and you play with those chips. If you do that then there is really no point in speculating if it would rise or fall, you are only left with just regular and the old fashioned gambling.
