I don’t think there is any accurate data when it comes to how many women are into cryptocurrency trading, and moreover I don’t know how Robinhood got to know they have more females joining their platform or how they go about attracting more females to their platform.

Anyways, this is how it has always been, in a space like this there are always more men than women, just like there are more women in the nursing field than there are men. Things like this you can’t force them, people are free to do whatever they want to do. I believe that with time we are going to have more women joining the community.
