As soon as this ends, absolutely all slots begin to take money.
How do you win and lose?
Returning to the context under discussion, the statement about slots gives you winnings at the start but over time the money is taken away. There are 2 points I want to convey. First, agree because based on gambling schemes, many people including myself have experienced this, but this applies to 1 casino and not to other casinos. Second, I don't agree because I played at one of the crypto casinos from the first deposit I made up to 5-7x the deposit and never got a win.
So in my opinion, whether it is regulated or not, you just need to control the bets in slot games, for example trying to move from game A to another game according to different RTP levels.
I have also made a thread about gambling patterns, maybe this is suitable for you with the title Gambling Distortion Patterns
