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 
at least we still hold the coins we already buy, because if we are confident with the increase in coin prices that we have. Surely the moment will come if we are more patient and wait. The most important thing we still believe in the miracle.
