Bet big to win big? Or bet small over a long time to be safer?
Betting either way will result in you losing so what is the point in pussy footing around with small bets? I you're a gambler then gamble big and maybe one day win big and walk away.
I'd strongly advise against that. Unless u dont have the time and only want to gamble once. If u do have time, I'd like you to take a look at bankroll management and bet accordingly. Increase/decrease your bet size with respect to your bankroll. I generally start off with a Bankroll of 100mBTC and I bet at the max 10mBTC if Im really sure about the outcome. Otherwise its 5mBTC this way I get to test my sports betting prowess and make money accordingly.
