But it is little bit dangerous as well. You need to teach yourself where to stop.
Yes where to stop and at what time should gamble, I mean gamble when the odds are really high, so even betting with small amount can earn you good profits and even if you loose it won't affect you much as you have invested small amount, But it's better to stay away from gambling or gamble just for fun, trading sounds great when it comes to growing the bitcoins.
