You walk into a casino, and you play roulette.
You bet
$10 on black,
lose
$30 on black
lose
$90 on black
lose
eventually
black comes out and you win.
I think the only thing stopping you would be the table limits?
Yes it could be table/bet limits those casino have or your bankroll. This is pure martingale and you might actually lost all you have when trying to recover your losses in this way. I have even seen 10 red streaks on roulette before
