Today's market is growing because of competition; Apple vs Samsung or Walmart vs Amazon. The point it doesn't matter if they keep working on there improvement of product. The market grows always when there's two options in the market.
In Crypto, we can see similar trend in between NEO and ETH. As long as there's a competition both will succeed in the long run. Obviously would share some market cap but wouldn't steal each other value like BCH and BTC.
I don't know if there's a news on Ethereum coming soon, looking at the charts there's not much of sell orders. In that case there would be one chance and i guess you know it.
Neo - Matrix just started to catch up which is something is on it's way. Right now it's more about profit percentage than price. A simple percentage graph or even price can tell you 100-200% vs 25% 50% gain.
Hint: Neo is standing where Ethereum was last year at this time.
