Its not to infinite, its 7 bets if you lose your up start over at eazch loss, and on a max bet 200$ table it works fine, you just go back to your minimal bet each time you lose.
You can't be sure if it works i mean i have seen a similar strat in past on blackjack itself and he told he was able to make a good profit but when others tried it not everyone got any success , maybe you try this strat and even win according to how you planned but your experience would surely not be same for everyone
It's better to try on dice as the house edge is also less so you don't lose that profit
