Yes there will be a couple coins that are very valuable in a couple years but the vast majority of them will be worthless.
Only coins that do things will be valuable. Coins that you have that are just there to hopefully go up on value so you can profit will be worthless.
Its like the dot com boom. You are betting on websites. Which website is going to get the most visitors. Most died.
The many coins and tokens I have are also worthless, the main factor is the devs. there is no serious plan and action, when the price skyrockets (maybe they pump self) then they immediately sell and when they get the profit according to the target then they prefer to create a new project rather than take care of the previous project.
