Great post.. if you are asking my opinion then i believe that a crypto revolution is on the horizon and will take away most of the sh*t coins from market away which are almost 80% of the entire cryptocurrencies..

As for the thing whether a coin should exist or not in the first place is a tricky question. Most of them blockchains created coins to get rich (in simple terms) and i dont think they care if the price of their coin is at 0.45$ or at 45$...

Excellent example given of ripple.. come to think of it, why does ripple even has a coin in the first place..
