Look, I wagered 914 DOGE with 10 bets, while losing nothing, which was pretty much expected for playing with 98% win chance.
I think, you'll agree that if I were betting with 49.5% win chance, I would, most likely, lose at least 2 bets within 10. So my balance would decrease by 183 DOGE, (most likely), instead of being increased by 9 DOGE.
If you play with a very big balance, and make tens of thousands bets, it almost doesn't matter what strategy you are using. But for a balance that is just 10-20 times higher of your bet amount, betting with the highest win chance possible is definitely better than anything else, if your aim is to win a wagering contest.
You can do any strategy you want, you can gamble however you want to gamble but at the end of the day if you are not lucky you are going to lose a lot of money and that is the end of the deal. If you want to just gamble as much as possible my suggestion is to have enough funds and gamble with minimum allowed bet with 98%, you can still lose with that but at least you won't lose much.
I agree to you everyone have their own strategy while playing dice game but if your not lucky you will end up losing your balance but for me I prefered a 80 to 85% win chances. I almost used a lot of strategy but in the end nothing is working lucky is the chance if you want to win profit.
