Is it really true that if someone want to earn big from gambling he need to make a higher bets? Yes he can also loose but if he is lucky enough he can earn big amounts too. People can not make profits with lower bet amounts like .05 etc. you need a higher amounts bets.
I think you can also make profit if you place a bet around 0.05 btc and up but this is not surely will happen often and even you place higher than the said amount like 0.1 to 1 btc there's possiblity that you will lose the probabilty to win will remain the same even if you change the amount of your bet and if you really want to become rich you should never stick with gambling .
