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.
If someone thinks it is just way to get rich fast or trick they probably can not be curious about it. I agree that whether someone is interested in cryptocurrency does not depend on if they are man or woman. As you said feeling responsible can make someone interested in something. Woman who needs to earn money for herself or her family will look at any way to make money or invest. This need can actually create interest in something new. It is about looking how cryptocurrency could be helpful not just about technology itself. So some people might be interested in it naturally but for others they may become interested because they need to find ways to be responsible and earn money.
