If you don't the basics of trading then it is same as gambling and also if you want to make a quick buck from profits like by doing a day trading then it also same as gambling. But if you invest for a longer term then you got better chances of making a profit from trading, and this kind of trading is not same as gambling.
But for some one experienced in trading then surely it is not similar to gambling or even he/she can consistently earn money out of it for a long term.
I think in a way, especially if you're new to trading and are just trying to find your way around, it similar to gambling. But as you gather information and experience, risks would be lessen as it's important to know the timing on when you'll or send coins. I've known a lot of people who've been successful with trading that started out losing coins at the start.
