According to me , the sad true is only few alt coins will survive and make their product reality. So to be success investors , people should be more understand those coins. Most of altcoins will death.
Majority of altcoins were started without any knowledge and they are only paying the dev that comes from the freelance to work with them all. that's why a lot of altcoins are getting fallen caused by they have no enough knowledge to develop the product.
from 10 altcoins and 3 will survive and the rest will die.
