Man vs Vegas
That link is to a thread about Man vs Vegas. Its a tv show that is currently going. The guy on the show uses the martingale betting system as he always bets more whenever he loses. He has a pretty big bankroll and is playing most games. I think its the closest thing to testing the martingale betting system in real life with a pretty big bankroll.
To the people that have watched the show. What do you guys think so far? I mean im not 100% certain its the martingale betting system, but its close. I mean he bets more when he loses, until he reaches the table max, but im not sure.
