I don't think Ethereum is lost, It is just because of Market is very Volatile, market price value of ethereum is dependent on the volume of investors put in by the investors, the consumer's confident or market behavior goes up and down as posted in the market trading, yet, Ethereum is one of the most stable, secured, with good market structure, clear fundamentals does remains on top among the ALT coin posted in the market. as always observed market correction comes after the market glitz. I am optimistic that Ethereum will come back soon once the Crypto and ALT coin market corrected itself. It is still on the 200$ level. let just monitor the turn of event the market.
