If you are a holder of both coins you are in a win situation, every holders of both cons don't care about the competition between the two coins as long as they can give profit, volume and development, I'm ok with Bitcoincash moving closer to Ethereum, but i don't think they can pull down Ethereum to it's position with the current development Ethereum is implementing.
