This is the entire history of Ethereum.

It looks like a rising head and shoulders pattern with the price having crashed through the neckline. Definitely a bearish signal. The head and shoulders patter is clear also in the logarithmic chart. Based on chart analysis alone I would not expect the price to climb anywhere near the ATH in the near future (read: this year or probably next year, either). It's possible that the market has taken into account that the Ethereum Foundation is not sure about how exactly to go about implementing a scaling solution. Meanwhile ETH tokens purchased for holding EOS tokens are being liquidated which is killing the price.
