Both are profitable and risky, I am not a trader but I can understand the way points of trading like in day trading it is profitable within a short period of time but the consequence is we should always attend on exchanges to watch its actual value so that we can sell at high price and buy during low, and the risk of that is when we have missing to trade at its last minimum price with respect from our buying value then the result is we should have to wait again its high rising, and the essence for all of this is we need a lot of time in market exchanges, while holding it takes time for us to be profitable but no need for us to monitor every time in exchanges.
