B) You used autobet and you kept losing bets until it cleaned out your balance?
If B, then I hate to break this to you, but this is why I keep telling people never to use Martingale on their bets, since there will come a time when you hit the small probability that each of the 10,20,30 bets you make will all lose.
I believe B ~LEL
Fun fact about martingale and same bet, remember when you are losing the bet you are not adding more chance win. Let's say you are better to under with 50% chance and feel that when you losing the bet will increase your chance to win.
This concept was completely wrong, no matter how many losses you are the chance still same 50% and will never increase. But as always, everyone just things when losing and stick with the same bet they feel the winning chance was increase and make them rekt because red train.
