many people suffer losses in trading but that does not mean you have to be frustrated or assume that trading [is not much different from gambling] in trading is that you can profit if you have expertise in analyzing coin prices. and gambling is luck, speculate as you like without having to have expertise.
That's their difference but they have something in common, which is the risk.
Trading is not easy as we think, though we think it's better than gambling but without putting much effort to improve and develop a working strategy, things would not be easy and a trader might fail in the long run.
In gambling where you use luck, you can't win in the long run, but in trading you can if you keep improving by learning from your mistakes.
