Precisely. Or what if you're some random grandma that has a wallet (since we're living in a make believe world where this is easy to create). Imagine you've forgotten which blockchain your wallet is on. Will there be a search box to find my wallet in this mess of combinatorics that is a login page?

I mined a teeny tiny bit of Dogecoin years ago. One of the times it spiked in price, I decided to convert my teeny tiny bit into Etherium. So I used a wallet on a cryptocurrency trading site.

Do you know what site that was? I don’t. I can’t remember. I think the password may be in my password manager, but I’m not sure. I’d have to go digging.

But I am SURE I’ll remember which of the 1200 common block chains I use for my credentials.
