Strange that he always lose. Never seen such a guy that has a terrible luck. Maybe winning in gambling is not for him? And the reason why he keeps on gambling is maybe not because of the profit this time but because he only want to have fun.
I'm sure there's a win in between. Not all have terrible luck but the timing to stop is not just executed properly. Since that person might be aiming for more profits, even though luck is always there and giving him chance to win, he still continues to play and the worst thing happened. The same cycle will happen again over and over again the next day and so.
As always, there's a thing in the gambler's mindset about why should we stop if we are lucky never realizing that it's now the start of the trap as they will just continue to bet. I admit, even for me, it's really hard to stop when we feel lucky and it's obvious that it's there while we play.
Just a while ago, I'm playing in a fiat casino with a capital of $20, spare funds on my fiat wallet app that is popular here. I managed to get winnings up to $300 for just a short time of playing because of that big multipliers. Since I'm feeling lucky and my capital is small, I decided to play more but someone got hit on my head that I need to take a break after experiencing no winnings in about, maybe 30-40 spins that I never experienced playing at crypto-slot games. I end up taking $200 at the end lol. Just imagine if the amount involved is decent.
