Me? I don't use the term "crypto-bro" so I don't have the authority to dictate how it ought to be used.

The impression I get from the term is that it can apply to any male, but maybe it applies slightly less to any male who has a much stronger relationship with their wife and family than they do with any friends or acquaintences.

But that judgement isn't necessarily meaningful until someone actually uses the term that way. Really, we want to know how THIS SPECIFIC person uses the term.
