The best way to motivate women to use bitcoin is to buy them shoes using money out of bitcoin. My wife hated me when I do bitcoin activities before but when I cashed out my bitcoins and bought her a shoe she was active and positive on bitcoin ever since.
Your wife loves shoes that doesn't mean everyone's wives will love it, this is the worst idea, and if women wants to earn money on their own then they will take initiative or else no one can motivate them.
