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.
A responsible player and someone who is good with finances should really be able to have the self control to walk away when they've had enough. A maximum losses block is a poor way to look at restricting yourself, maybe switch to a deposit limit instead, however it does not get around the root issue here - which is that you could simply start up again at a different casino when you reach the limit, so it's the poorest form of defense if you think you have a wasteful or damaging gambling addiction. You need to take a serious step back to reassess whether you should be doing this activity at all, give yourself a break from it if you feel a lack of control has seeped into your play.
Exactly, I don't understand why most people don't get such a simple thing that you can't get rid of your addiction just because of a tool or a rule set by a single casino platform knowing that there are a lot of other platforms available out there that would allow you to gamble with them when you want to, and when an addicted gambler feels the extreme urge to gamble, they would always look for ways they can gamble even if they are restricted at one place.
So it's basically the urge that needs controlling and not the losses being cut down by the casino itself when it's not even their responsibility. It's your life, it's your money and it's your problem if you are not being able to stop yourself from excessive gambling, they won't set the stage for you to perform, you have to do all that yourself.
