You cannot force interest, and it is the same for even a man who is not interested in cryptocurrency or anything digital and sees it as a get-rich quick scheme or scam. Interest in cryptocurrency is not gender selective and it is all about responsibility, for a woman who looks for a way to make money for herself or support her family will consider any means to make money and any sort of investment to make, that brings me back to the side of interest because responsibility sometimes brings interest.
agree with what you said that we can't force interest on others... be it women or men, if they see that cryptocurrency is something that doesn't interest them and they think it's a scam, then no matter how we explain it to them, they won't be interested in learning more about cryptocurrency.
maybe what we can do is just provide some information, like what cryptocurrency is, and some other basic things. if they want to learn more about cryptocurrency, then they will definitely ask more and find out about it. just let them learn it naturally.
