It depends on you if you want to hold or not.

More often if I made already a profit I already pulled out my funds because I already earn on it but if you think the profit is not enough to hold again. Sometimes holding gives me a lot of benefits too when the market price of the coin increase and there is something changes in the market movement ( I'm no a professional on market reading movement but still I know what are the next trend ).

Follow your guts sometimes fear is good too. When you have the additional sense that you think the market is falling down soon so pull it out if you think to get profit go ahead hold for it.
