I don't consider trading as gambling, because gambling is a lot more risky than trading. With trading you can earn if you have good knowledge and you study the market , but gambling depend only in luck
because it is not gambling at all, in my opinion trading is a think that has a bigger possibility for people to make money than gambing
base on my experience now you can't make profit in trading when your not going to buy alt coins the bigger you buy the bigger you lose the profit its like taking the risk too but the difference on trading and gambling is you can resell the coins in much more cheaper price than the original one
