Because basically women always receive directly instead of waiting for one of the investments the reason why women never invest is because of the long wait process and most women are easily scared when assets go down so women are not suitable to be in the crypto world
I think women are much quieter when it comes to crypto, maybe more women own crypto than we think. My Wife she is probably one of the exceptions, she has been advocating crypto now for years and despite the many bad experiences she has had and the bullying, she is a staunch supporter and survivor and thanks to her, now almost everyone in her family know about crypto. It is true, we need to make crypto attractive for more and more women to enter. We say women like to spend, but many of them also make great savers, so getting them in to hold long term crypto might be very attractive to them. I believe it is more the technical aspect that has scared many off and the scammers/hackers.
