Well, if there is anything this market has shown and that I have learnt, is the fact that anything can happen at any point and at any time. Even what most of us believe to not be able to happen. I won't be surprised if neo surpasses ethereum in the near future. I actually think that NEo itself is another great coin.
I don't think becuase NEO and Ethereum Price difference is huge. In fact NEO is good project but it will not compete with Ethereum due to its low market cap compared to Ehtereum. NEO is another good Altcoin to invest in after Ethereum,Ripple..
