But if you can't control your emotion I suggest don't try some alt-coin trading.
Gambling is unlike trading because if we want to trade then we need to have atleast some knowledge for it. If we dont really have any knowledge or skill then it will be gambling pure on luck. I dont think that every trader have the skill to trade, some just make it looks like gambling and try their luck. Atleast thats what I know but still it is better than gambling
