Why don't people understand that hitting x streak bets on 50%,
you have to get immensly lucky or have a ton of bets (millions),
x = streak = your chances 1/2^x
e.g. 20 = 2^20 = 1/1 048 576 bets
Your problem seems to be of gambling in general, the mind psychologically remembers the losses more than the wins,
so for example : Once you were losing a lot you were trying to make a comeback and then hit a 15 win streak, continue hunting break even or profit, but you still lose in the end, you will remember not the 15 win streak, but the overall loss.
