I've seen today one article from TechCrunch, that says that more than 1000 projects are dead already. Also, there is another report from Coinopsy that are 247 dead coins. One of the famous projects is BitConnect. I guess everyone knows this crypto pyramid.
Most projects and coins will most likely die, and only a few will survive and grow.
It was the same with the .com bubble. Some have survived and have become big.
And look to the situation right now - everyone can launch his own ".com" and there is no need to launch IPO
Will this happen to cryptocurrency? I think not. I hope so
