keep it. Even though NEO is more or less a copy of the original, which is Ethereum it's still a very good token to hold. Some of the reasons to do that is because NEO is kinda acting as a hedge against ETH, which means that if something happens to ETH and it fails, in one way or another, then the second best option out there would be NEO. Some are saying that ETC is a good alternative to ETH but that's not tha case, the team is not implementing anything that is worth considering and it only lacks behind the shadow of ETH. NEO at least is innovating and is trying to get regulatory approval, it serves as well the Asian market which is kinda huge considering that many new users will come from there, so you stand to earn quite something by holding NEO.
