I think that even after five years, NEO still can't compete with ETH. After all, ETH's family is too big. And i even reckon ETH can surpass BTC in market value in five years.
Agree with that and even comparing its price today, NEO is far from ETH. Five years is long enough to speculate what could be possible to happen but it is for sure both coins still exist and still ETH will lead among all altcoins currently listed on the market exchange. Eth have already establish its platform and it is also known to all investors than of NEO that's why it couldn't replace ETH on its place.
