In crypto world there is a threshold which we call "miner limits" which would yield a result, a price that would mean a crypto currency should not go down under because miners would lose money. Ethereum is at the limit of miners losing money, right now they are making profits but it is so small that it doesn't worth mining it and as soon as miners stop mining or miners stop selling than the price of ethereum gets higher because the buyer/seller level would be unbalanced and will go up until its balanced again.
It means right now ethereum is at a price where it can not go lower, if it does than more the same because it will have to get higher in order to feed the miners so we are at the bottom price it should hit and from now on it should only go up.
