this is true.
although you should never forget about a golden rule in gambling: "never bet more than you can afford to lose so maybe 0.05BTC is a lot for someone to lose and maybe 10BTC is not even big for another person to lose.

anyways, you can do whatever you think is right for you and helps you make more profit but never forget what you are doing, you are gambling and it has risks which means you can lose the big amount of BTC that you put down for your bets.
