I believe there are more things if we look under the microscope, but this started, in my opinion, because of the price. No one wants to hold Ethereum now just because there’s not much movement with its price. Many people are seeing the trend now where Solana is even really being taken off with all the news, and I think that’s just where it started.
I'm sure a lot of the pressure everyone is putting on the ETH is inspired by SOL
SOL beat ATH, the network is being used by many new users, there is a huge volume of trading, many protocols using the network...
And it's working relatively well
Not to mention the tokens they release on SOL, which are doing very well, such as JUP, Kamino, Drift, etc...
When an ETH holder sees all this happening, it's hard not to be dissatisfied hehehe
