You need nothing but holding, your money may decrease too much but it does not matter you still hold them. I never trust other things except holding. If the coins are really trash you may not be able to see their rise again 
I agree on you mate because we do not even know what will happen and we cannot say that everything will be good. Holding has its possibility that the token you have will move to be in the higher portion of the value or the price. It is better to predict for good than never.
