Martingale is a strategy of doubling every next bet after you lose, no matter how many times you lose. If losing
streak is too long you will lose entire balance.
On the one hand, Martingale is strategy made me feel interested in continuing to play and bet at a later stage, even though I lost. But on the other hand, I must have a lot of capital to implement this strategy, and certainly not an easy matter if we have lost 5 to 7 times in a row.
Without raising bets or odds there's no way to recover after losing, or to make profit, in gambling you need to raise bets and odds, the point is to have a luck and hit the right moment for that!
It is possible that we can increase our chances of winning and restoring balance if this strategy works well, but if not we will not get anything and that means we lose all the balance we have. Whether or not a Strategy is good I think depends on luck and the way we increase opportunities. Dice is a very interesting game for implementing the Martingale strategy. But several times I ran out of balance.
