This is not on fiat, at best it points out to the fact that are far less women in this space than men and basic supply and demand applies here to and people react to that.
Why is that? I suspect because of personality traits differing in men and women, this is a biological reality not caused by sociological effects, that tends to make men more interested in "men fields" wich includes Bitcoin, nostr and a lot more stuff that modern naïve people tend to blame on patriarchy and not in evolutionary traits so rooted that goes literally back to the chimps
