Do you think the coins created with premine and IPO, and even with innovations, have a future and the potential to achieve massive adoption and overtake Bitcoin?
If your definition of success is that it must overtake bitcoin then you have very high standards. I would certainly judge NXT a success and this had an IPO. XCP as well.
This. Nxt - a coin that didn't even exist half a year ago, is currently in third place according to Coinmarketcap.com, just behind Bitcoin and Litecoin. If that isn't the definition of a successful coin then I don't know what is.
