It is not. But if you believe the max profit is the only thing stopping you from winning, you can play on JD which has a min bet of 0.00000001 clam and a max profit of over 200000 clam (=1100 btc).
ok what if a user start martingaling at 100 coins ?can he recover after losing 3 bets even if he knows that he is going to win the next one ?
no he cant because doog dosent wants to lose .
Nope, but if you honestly believe that martingale is a winning strategy in the long term, you could use a lower base bet. The 200000 clam max profit on JD allows you to double your bet 44 times at most. And btw, do you have 1500 bitcoin and are willing to risk losing them? If not, it is not an issue for you.
