I dont think people are out of the ETH at this moment. Literally I am seeing the biggest buy wall in the HitBTC at this very moment. This was supposed to happen as the ETH is still very much loved currency for the people and they will never let it go in the altcoin world. The crypto currency are currently falling, however most of them also recovering staring today as we can see the green market everywhere. So on the first line of defence ETH will not leave its place and neither it will replace the bitcoin's position too. However, the ETH does have potential to make it fall in the future if bitcoin doesn't make any more progress.
