Help about Ethereum

Hello, I’m new to the community.
When an exclamation point icon appears about Crypto Wallets, I click there.
This one put something about Ethereum and created an account without knowing anything (and later I realized that it does not generate cryptocoins in the browser).
In this browser can I delete my Ethereum account and recreate it?
And if it can’t, how do I get it to connect the Ethereum program to my Brave wallet?
I hope you can help me with that problem I am having, thank you.

The Ethereum crypto wallet has nothing to do with your Brave Rewards wallet. It is completely separate.

Crypto wallets can store all the cryptocurrencies, right?
