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 
Haha, you think the market is so simple, just hold you can easily earn a profit? What if the project after a year you hold the project generated many disadvantages, the exchange delisted token of the project, the key members leave the project?
