everything is still ok. if you compare with the past, ETH price is still high. ETH's manager is Vitalik Buterin. I strongly believe that he will have the manor to develop ETH technology. After that, the price will grow back.
To be honest, i don't think that Vitalik will increase the price, there is no way for doing it artificially.
Anyway, i think that the price of each ETH will go below $300 and then will start to rise again, just like it always happened on the past.
