If you hold any ETH i would advise that you hold it for the long term, may be tempting to sell now, but if you are happy to hold onto it or invest in long term i would definately do so. Reason for this is that IBM are leading the development on a project called Hyper Ledger, which will speed up the process of commercialising Crypto on a major level. Whilst BTC is a main player, there has been a huge focus on ETH.....IBM, Microsoft, JP Morgan, Deloitte and R3 amongst others are investing millions into the development of commercial software for ETH. Other major banks around the world such as RBS has of spoken of their interest in ETH....rather than BTC. Search JP Morgans 'Quorum'.
I work for one of the companies mentioned above and i can safely say there is 95% that ETH is going to become a massive crypto to be used commercially world wide!
