I don't think gender should really be an issue or a big topic when it comes to crypto space. We're all aware that majority is male, but maybe another factor of that is majority of the population with regards to technology and investment related stuff are also men. So when you combine tech and investment, it will still be men.  

About your idea bringing someone to attract women more in this space, for me it can be any gender as long as they are influential to women. It's possible but probably won't make such a big difference... Maybe women are just less likely to be interested in this kind of activity as it can be too complicated and risky.
