I found this article quite thought provoking: https://medium.com/cryptolinks/cryptocurrency-market-where-are-all-the-women-7a1c2e62c0df
I had never put much thought into it before, but Blockchain is a very male dominated industry. I don't see that as a problem per se, but I wouldn't be surprised if women found entering the space intimidating/have a lot of barriers to entry.
