ETH had problems with installing the constantinople-protocoll. This should have been the first step to implement the Casper-Protocoll, with that changing from PoW to PoS. But some security problems caused to halt the Constantinople protocoll.
So no new good news for the token of Vitalik Buterin. And concurrence isn´t waiting.
Technically the price of ETH is within a continuos fall since january 2018. I´ve had a little hope january 2019, when ETH seemed to have enough force to leave the negative trend channel; but it has been a false breakout. After forming a double top (very often a negative sign) it fell back into the trend channel.
In comparison to BTC there is much space for lower prices. If the cryptocurrencies are coming back to their beginning in 2016 (start of the rallye), BTC would fall on ~ 2.000 USD but Ethereum would fall on ~6$.
This would be horrific to the most investors who stepped in in 2017. But even if it´s a terrifying scenario, it´s not unpossible and it´s not unplausible.
