I think this is pretty normal in blackjack. In my case, I didn’t just lose 15 times in a row, it might’ve even been 30. I don’t have proof, but experiences like that are hard to forget. There are really days like that—sometimes you’re unlucky, sometimes you’re lucky. And the best thing you did was stop playing right away when you weren’t feeling it anymore and were on a losing streak. Unlike me, who kept betting and betting despite consecutive losses instead of stopping.
