It is like an addiction , when you do it more you and you loose you want to do it more . till you become completely broke and optionless!
trading is not like gambling because you can do it with knowledge and analysing.
Its all about the luck mate. I know many people and few managers here who are earning more than 10 BTC per month on the gambling websites. You believe it but they do it with only luck and off course lot of money. I have understood one thing about the gambling, if you put more money on that site then you get lucky and earn more and more money. Thats the algorithm there who behaves!!
Off course trading is just different art where you have to be patient and you dont need much money to play it really.
I am sure that both coudl turn out to be good or bad according to how you treat it, play it and how much you trust in the luck.
