That remains to be seen, actually. When you trade blindly, you will very soon notice that you do something wrong, you won't have to wait like a couple of years before you come to understand that your strategy simply doesn't work. You just shouldn't be blind yourself. But if you are, then no strategy will bring you profit, neither trading nor holding. In this way, it is really hard to say decisively and conclusively which approach is better and which is worse. Personally, I think that trading is a faster way to see if you are doing something wrong and then make changes to your investment decisions.
