It is possible to exclude yourself in the way OP said, but unfortunately, as OP said, you cannot use stable coins to distance yourself from the risk of fluctuating crypto prices.
In my opinion, whatever method a person uses to exclude themselves is very good, but it all comes back to the desire and commitment of each gambler because it would be in vain if a gambler staked the budget he has because if his mind still has the desire to gamble, of course he has other methods such as tried to gamble, borrowed a little money from a friend and gambled secretly.
A strong desire is an important role for gamblers who want to reduce their gambling activities so that in any way gamblers can very easily limit themselves so that they get into the habit of not gambling too often.
