i do gambling with a very very little amount of bitcoin. and the other thing is that i do gambling in a limit i have a fixed limit for gambling and i never try to exceed that limit. and that i have yet not lost so much in gambling.
I'm starting to handle my funds like that a lot better in different places and wallets and I have learnt to sometimes just leave the btc already in the account and wait for a promotion.
i think even if you try to use the other's wallet funds on gambling and use restrictions for gambling, if you're an addict then it all will never mean, You'll never know control game when your money runs out, surely you're going to take any more money from the wallet and gamble again,,
