It seems like a cryptocurrency wallet would only attract a very specific kind of thieves and would only apply to cases where you'd normally expect crypto wallets to be present. Given the "sophistication" of some of these attacks I would be surprised if the people behind it would even recognize a crypto wallet file name, let alone know how to import it and actually steal the coins. I remember seeing another service that provides usernames, emails or links to seed into your DB and will alert when the link is requested or spam starts coming into that. I think that will be more effective.
