People who have extra money or big bank balance might be able to sustain it, else for smaller players martingale might not be an option. One should be able to chart out how many loses in a straight streak they can manage and play and will they be able to sustain even if 10 straight loses or say more for that matter. This would depend on everyone and amount and risk they are ready to take it.
When it comes to sustain then there's no denial that big or whale players could really always have the advantage on making use of several strategies and
with due on having a big bankroll then they do always have the edge since they do have much more space on testing out those not only limited to martingale
but also in other strategies as well.For those who had limited funds specially with bitcoin amount then small time players wouldnt really that much of making worth of it
but to bare in mind that even if you are a whale that wont really exempt you on getting wrecked because there's no such thing about unlimited funds when
using martingale.
