What do you mean by "normal"? I mean it is obvious that it is not common, usually you do not have 10+ streaks of under 2.00 when you look at average what happens in crash or dice games or even roulette. However when you say "normal" in that way I assume you try to say something like casino tried to make you lose because you were gambling and winning, so they had to go out of their way to figure out a way to make you lose and they manually made you lose 10+ times in a row to get all of your money.

It's normal. But it's rare to happen, OP is just unlucky to have witness those red streaks occur, and it happens that he is increasing his bet as red crash shows.
It's just like the winning streak for green one, sometimes you can notice 10 or even more green streaks on crash.
It's normal if, you'll see it if you are playing more time on crash.
