You could make the argument that if all of the capital in crypto only had to be spread across 50 coins that that would make each of those coins extremely more valuable. In light of that thought, is the huge variety of Altcoins ultimately a good or bad thing for crypto?
It's a good thing for diversity but it's not a good thing because the market becomes saturated with coins that people don't really use. As some people in this thread sayed, the next bull run will show what coins worth keeping and what not.
