I'm not arguing that crypto is dead, but adding a random crypto-related feature to Edge is not a strategy, it's a "me too" bit that just seems odd.

Brave has a built-in crypto wallet but it makes some sense in their offer, this one does not seem to.

Unless you think large amounts of people will migrate to Edge because it has a built-in wallet? It does not seem likely to me, but I'll be happy to be corrected in a few years.
