According to the website
https://coin.dance/stats males make up 97% of the Bitcoin community. Why is the Bitcoin community dominated by guys?
Because there are very few women in STEM (Science, technology, engineering, and mathematics). Feminists argue that men in those fields are biased against women and don't want to accept them, opponents argue that women naturally less interested in STEM disciplines. So, if you want to understand why there are less women than men (even though the data in your link might be incorrect), you should search for "Women in STEM" in general.
That's true, but that doesn't really explain the 97% number, seems like a far bigger gap than in other STEM fields.
I'd be very wary of the methods they used to get this result.
What's the ratio here on the forum, for example? Are there any stats?
