simple,its not possible to make any decent amount through gambling starting with 0.01 btc.Actually it would not be possible even if you start from 1btc because you will loose sometime for sure.If you are lucky you can reach 0.05 btc or 0.1 btc but you will surely loose them if you keep betting or gambling with them.
He can invest on casino bankroll and earn some profit. But surely with 0.01 BTC it won't be possible. Very low investiment to hope any good profit. I think to make it worth, the initial investiment should be at least 1 BTC. So, the investors can earn some income relativelly fast and safe if you invest on a good and trustful casino site.
