It is still unknown how will the market react to the incoming update of ETH.  Many are hesitant about the transition of it from POW to POS but most certainly there will also a group that will favors it.  So those who are in favor of the incoming updates will possibly do their best to make the incoming update look like a positive move.


ETH is somehow a well-established cryptocurrency so before it goes down to zero, we might see many projects become zero first.  Besides ETH caters several promising projects in its blockchain so that things will prevent ETH to devalue to zero.
