I think one of the things crypto gambling opened the doors to is widespread practise of martingale. I mean, any casino I've been to will have a min/max bet that at best allows you an 8-streak martingale. But with micro-betting thanks to 1 satoshi bets, people with 1 BTC back when it wasn't even $1000 were able to try long, long autobetting regimes that seemed to return consistent profits.
15 in a row is like 0.003%, 1 in 33000
I've autobet enough on dice to know that those tiny chances of hitting the 15-streak loss happens all too easily. I can do 33,000 rolls in a few hours - and have often done so. Even with the lowest dice edge online, you'll hit it even quicker.
It's weird because I read his reply and I was thinking "Wow he read my mind" and only after you copied his post and mine I realized that he copied my entire post.
Yeah, plenty of these alt accounts plagiarising people's posts. Reported =)
