For me, the longest streak I had was around 100. Well that was because I had my settings on 90%+ win rate. That was nothing special though since I had a really low multiplier on, so I was able to win a long streak. I guess, I would be more interested in people answering how much was their winnings in percentage compared to their initial bankroll and how much streak did they get to get that winning amount,
That's really a good long streak, I couldn't cross more than 28 even my multiplier was low though with like 40%. I made my highest with 33% was like 26.
So technically the later can be considered higher. Recently it gave me a pretty bad long loosing streak, which made me stop at the moment. Now it seems I was quite lucky to reach that streak
