I do not think ETH will drop to $ 50, although ETH drops to $ 170 but it immediately rose to $ 230 and now prices are stable at this level. I think ETH price will increase to $ 1000 at the end of year.
If we see that the whole market is bullish is the chance great that Ethereum hit above 1000 dollar at the end of this year.
According to Tom Lee ETH is preparing for a vigorous growth. He said it will be 1900$by the end of the year
