that is probably the main reason for such bad streaks, I think a few last bets was 3x (big mistake)
it was not straight martingale, I always either reverse or start over the bet amount after certain lose streak
within a month period before I've never encountered over a 16 lose streak
within the last week, I got hit badly (lose 60-70%) but never get busted
I managed to recover and accumulate some profit... I got carried away and lose control
I was hoping to win back all my (previous deposit) losses but ended up adding to my lose stats
That's what I thought, thanks for the elaboration. Although, as you can see from the comments above, this could happen even if you were playing with 2x multiplier only. The thing is that the more bets you make the higher the chance of hitting an extremely long losing streak, but there's also a chance of hitting it with small amount if bets.
There's a 30 winning streak as well to make you feel better.
I had experienced 18 winning streak myself playing with 2x multiplier. This happened only once in my long history of playing dice, probably around 2 years ago, and when I saw that with my own eyes, I thought to myself, it means I can get 18 reds in a row as well, and I've started treating martingale with caution since then.
