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.
For all these, first we have to make them to believe about the cryptocurrency and about its uses. If they believe show the proof of income got through it. Show them various sites accepting bitcoin as payment. Now ask whether they are interested or not. If interested proceed to teach further else just drop it.
I couldn't agree more with what you just said there. Its all about this.
