14 reds in a row is usual for me , and you played it with martingale strategy with 50% chances .
1 sat is good start to play martingale , you can get longer streak before your bet vanished . Also after you win huge amount , you can send it to your wallet at the moment.
only a few people can successfully withdraw their profits while playing on this strategy. in the end 98% people can't managed to withdraw profits,not even their bankroll!
