IT really is the only way to do this! I never ever ever deposit anything more than I know I can afford to lose. Not for crypto anyway. I made the mistake many times before with fiat casinos where you can use credit card (so dangerous because the interest piles up).
Which is why I love crypto. To get it and deposit more you have to BUY more first and that extra step helps me to stop:)
This is one of the reasons why I didn't activate my credit card I worry that I can't control myself people can also learn from this
Placing a lot of crypto in a wallet can also be a problem There the casino will continue to influence the mind to make a deposit
