I see more potential in NEO than in Ethereum, yeah Ethereum wont dissapear and will hold and increase price but it if you buy 2 Ethereum it may ( nobody knows ) reach 2000-5000 by the end of the year it'll be 10000 max for you. With 15xNEO if NEO price will go up 300 it already doubled price and i see neo reaching this price in 2 months, by the end of year i think NEO will be 1000 minimum.
It's still you own choice, but compared these two, NEO definetly wont stop.
