ETH looks bad right now. Reason: ICO's cashing out. Basically it's lots of people giving ICO's their ETH, which is then sold. So what currently happens is a huge selling wave.

However it will not go on forever, at some point people run out of ETH and have to buy ETH at market to use for ICO's.

Also people favor BTC right now because they expect a split (free coins on other chain, like BCC).

Now the bullish part:

Long term, all the ICO stuff will harden ETH. ETH fuels so many applications, it will become too large to fail, and more and more gas is used.

Also ETH will become POS - which means a lot of interest earning and "masternode" locking of ETH. Casper discussions are around 4%, not bad for HODLing.

Therefore ETH long term should be much higher
