stay away from gambling is good, but don't stay away from trading, it's not bad. come closer to it, it's not waste of time. losing money can come back in trading.
I used to use betfair a lot, and you can really trade in play quite a lot. As something like a tennis match evolves, you can trade positions and end up with a green book, or a red book. That is as much trading as FX trading is.
Trading something like bitcoin or an alt is pretty much gambling, especially if you do it with leverage. They are too risky to be considered real trading, and without any prior warning you can lose everything in no time (unlikely in FX trading, unless you were short the CHF!)
what ever trading or gambling you have to keep limit, but in trading like betfair for sports you get chance for both side making profit, like in cricket their you can see that when a team is in favorite in low odd you can lay it and in between the other team goes good then you will get other team low that time you can lay that team and make both site book, like this trading you can win always , let it be a small winning but it is better than a loss.
