ETH price is related to BTC price. When BTC show stable grow-up trend you will see ETH is going up as well.
There is no strict relation between eth and btc. Just look at the charts of bitcoin and ethereum prices since the beginning of 2018 and you will see how different their paths are.

Yet I disagree with the op that eth is dead. It still has chances to recover, even though for now mining it is really unprofitable, taking into account the fact of eth fork that makes eth closer to not being mineable at all.
Yes, I am not saying that ETH is dead or something, just that it may not as that crazy as that in 2017 when almost all the ICO projects can give you a decent return rate! However, facing with strong regulations around the globe, the good projects may emerge which may drive ETH prices up again.
