There is no reason for Ethereum to make an upward movement if everything is turned red, feel disappointed ? yes of course everybody will feel it, but Ethereum needed to adjust its price or was forced to move with others. It is all about manipulation and adjustment, so do not put your hope too much into it when the market is going down.
As I agree with your perspective, ethereum depends on market movements and does not have its own motion in crypto to speed up his weight, and about whether the person disappoints what's going on? Certainly who would be pleased with it, investing heavily in investors is so much so that its moves are so slow.
