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.
Wish it was, but in real it's not the best it's based on pure luck if you are lucky you have have a winning streak and make loads of profit but same with even a small loss streak you would be bankrupt.
