Trading is risky and quick profit is like gambling! I advise you buy some promising altcoins, which are cheap now and it is a good time to invest to them! Please do your own research before making your decision!
I agree with your opinion that trading is much risky yet profitable if fortunate by chance, thats why it is good to invest also to some altcoins that are still cheaper this moment because in the future those coins will rise up especially if you invest them in long term,and of course gathering more indormations will contribute big help... so that you can make a right decision...
