What if the coins in your wallet are short term projects like most altcoins are, would you hold short term coins for the long period? It'll surely be counterproductive If you do so, as chances are you'll not make any ROI cause the coins could prolly dump when you're yet to sell and you'll accrue losses from your own end, long term investment can only be said to be productive when you are actually hodling a long term project/coin like Bitcoin.
