Advise a reliable casino, with the ability to set the amount of maximum loss per week. It should be possible to deposit in cryptocurrencies, it is desirable fast payouts without KYC.
This doesn't sound like a very sane or sensible approach to gambling at all. Most casinos have this sort of offering these days, as promoting responsible gambling is a one of the best things they can do to keep politicians happy and not ban them. However there are so many offerings out there, that even if you put a stoploss on your gambling at one, if you're happy is that impulsive and uncontrolled then you can start depositing at another one within seconds. Unless you pick one that has the stoploss figure you want and then ban yourself from all the other major casinos. Really you just need to get a grip on your spending because it sounds like you are using a very poor strategy right now.
Yeah this also sounds like an unrealistic approach to me, the reason being that the approach seeks to deprive the casino a lot of revenues which may be against their own operational purpose, and also the ops made such possible demands due to his own personal interest without minding what the casino may lose from such event and features.
When the gambler lose a game, the casino gain more income since the staked amount becomes that of the casino because the gambler lost to the casino, so why implementing a feature that will limit their potential income.
