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
I'm not saying NEM is better than ETH but at least in one thing OP was definitely right: NEM
was cheap in December 22 and it had risen two times more than BTC by January 04, 2018. And now after decreasing two times more than BTC since January 04 I think it can be called cheap again because today its USD price is lower than in December 22. Since no way NEM can be called a sh*tcoin its price will rise in the future for sure, the only question is how much. I think we can expect a two times rise in the nearest future. Although I like and support Ethereum I think it will rise not more 40% in the same time period. (Please note that I'm talking about the nearest future here, and not about long term. )
