Hello 
I was wondering if you have any strategy when betting and what's your biggest lost
Cheers !
Most effective is martingdale strategy but it's up to you if you follow that strategy and don't be greedy it can cause you to lose all your money be contented.
Most effective strategy to lose all your btc, did you mean like that? Huh
There is no effective strategies, as discussed so many times before that it will always depend on your luck no matter what strategies you use while betting.
The reason of people's lost in martingale is the inability to call it a game when you are winning. With the strike of winning from it, people think that martingale is a strategy for a long run but the fact is, it is a strategy to give you at least 1 win with a decent amount of profit. Playing continuously with it will lead you to a lost. At least know when to stop everyday.
