I can say, that's normal. Yesterday, i saw on other popular crash game site, it has 12 streak losses under 2x multipler. If you think 14 losses aren't normal, that site will bankrupt since you only need bankroll which can cover your losses 14 times in a row. Each hash also unique, you can't say it's not normal too since no one knows what's the next result from each next hash.
Unless you've experienced something extremely alarming till then you could not understand that feeling. What he is believing is totally typical, only victim knows that losses 14 times in sequence. Luckily I've been never going through such horrible things, and wish none one experience such things.
I saw over 20 reds in crash at x2, and I believe it can go over 30 reds. But in the same time I had over 50 winning streak at x1.5! Its gambling and more you play you will have crazier streaks!
Crash is more interesting for me when I am trying to catch some higher payouts, over x10! It's time when you need to wait for a win, to rise your bets slowly (after 3 or more reds) or exponentially (every next bet higher for 20% more or less), and when you win you always have a nice payout!
