It's not a secret that NEO is the Chinese version of ethereum. I think by now, NEO is also one of the most valuable of cryptocurrency and most valuable platform. NEO will have huge increasing of price nearly and NEO may be in first 10 main altcoins also..
If we looking for ethereum, ethereum is the second main stable cryptocurrency in crypto market.
It's still in its early stages but it has a lot of potential to grow from here. The Chinese are pretty good with their technology, so there is a good chance that NEO can continue to go somewhere. There have been some doubts about the fundamentals for ETH lately as people are unsure that it's platform will be able to evolve with the rest of them, but I guess all we can do is wait and see.
In terms of security, I don't know much about the reliability of NEO. How strong is it against attacks?
