Having a good skill and a high-paying job does not stop you from gambling. Crash games and other games whose outcomes can't be predicted are just games of luck that people are using to pass time and try their luck if they can have a big win.
There is nothing too personal about me. I'm also a fan of the crash landing games, as I have used a few cents to make a few dollars from the game, and I must say the game can't be predicted to some point, but then again, if you try it without being too greedy, you can also get something out of the crash game.
Crash game is just like the same with other luck-based games such as dice, hi-lo, roulette and other casino classics. Martingale, D'alembert and other known strategies may work for a time, but it doesn't mean, it will work for all individuals that will try the strategy. It is by no means a way to earn huge profits even if you try those strategies. Luck will still dictate your fate on this type of game.
It will only be profitable if by chance you are already on the winning end and you stop your game and collect your winnings. But if you continue your game trying to hit bigger profit, then, I would say, the likelihood of losing it all is quite high. So before you totally lose all your bankroll, better pause and stop and call it a day.
