I believe that upcoming catapult update will change everything and NEM, a truly fantastic and cheap cryptocurrency with a unique and progressive proof of importance concept will challenge ETH at it's own game and replace the damned Buterin's $hit coin, which only old grannies with their cryptokitties find useful
Haha, this must be a joke? You can not be serious thinking that NEM will replace Ethereum. If any coin will replace it, then EOS is the closest one to achieve that in my opinion.
