Next bet in tennis match ** Ling Zhang - Danielle Lao (To Win Match= Danielle Lao) odds 1.55 in 40mBTC **
this is a risky one mate but if you win you will get big income and time to think about your winnings we all knew martingale is only good for quite some time but using it in the long run will let you lose everything. good luck mate.
Martingale is the key of this system, but not only one key. I used small odds n market prediction, this is the key too for my system.
can you imagine if you lost 4 times in a row with current 300 mbtc bankroll? 10-40-160-640 = negative!
martingale will never work even you have large bankroll , it will make you looks a winner just temporarily and the rest back to your skills (in sports) and of course a luck should be on your side.
