The ETH would further decrease to the price of $200 as it's the real worth of the coin and after that would gradually increase in price as the coin improves.
The current bearish market is the correction of large pump last year.
It's interesting how accurate some predictions can be. For example this one above was made when ETH was $280 and many people thought it can't go further down. Let's see if covfefe was right on the subsequent price rising. I personally believe that he was, since Ethereum has a great team behind.
There are manipulations on the market. Bitmain wants to make the BCH the biggest coin and reduces the price for the ethereum
So, what they are doing exactly from you point of view? Exchanging ETH for BCH? But to manipulate the market you need large amounts of ETH for that, but from what we know they have large amounts of BCH.
Also, I don't think they are interested in lowering ETH price since they are selling Antminer E3 ASIC which is inefficient even at the current ETH price, let alone at a lower one.
