Right as you say. My reference is the movement of Bitcoin trading on the Ethereum pump. Because of Ethereum, I think there is also a correlation with the movement of Bitcoin.
The whole market is centered around the price of bitcoin so the correlation is not only for ETH but all altcoins, the London hard fork on the other hand could push the price of ETH up and could also affect the price of bitcoin, we expect ETH to hit $4k again this month.
Correct but if you look at the chart for the last seven days Ethereum outperformed Bitcoin by a lot. Which is good I think, a little bit of decoupling from Bitcoin can't hurt especially when we are talking about a project that really stands on its own feet. It is not like Ethereum needs Bitcoin the way any other coins need Bitcoin to pump themselves. The upgrade went smooth and there is more in the pipeline, all things are good for now.
