we must make doubles betting from the first lost and keeps continuous every time losing.
The bad thing from this strategy is no one people around the who have unlimited money, this strategy is never work in gambling
many people have tried this strategy and they just got losing large of money.
Well for me its not the unlimited but when you know how to stop if ever gathered enough of your winnings. Cause even if you have many btc but you dont know when to stop then you just gonna donate your btc to that certain site. Because for me if i have money i always have 200% of my winnings. But even though i almost win there is always the need to gamble more. Even in physical gambling i do martingale and sometimes there are other bankers who could see through that style that sometimes they are preventing it.
