What would it take for Ethereum to not be influenced by Bitcoin?

Bitcoin drops in value, and the entire crypto market goes with it.

So im curious.

What would it take for Ethereum to not be influenced by Bitcoin? The market cap flipping? For a country to implement Ethereum as its currency? To be able to buy my ☕ with ETH? What service would have to be built on the ETH blockchain to change everything?

I'm curious in your opinions, and vision for the future.
