I think we should ask her to sit next to us and show them how they can earn from signature campaign, as we need to keep things simple at initial stage or else they will find it complicated.
Yes, that's it. You have to involve her everytime you will have transactions like buying, earning, trading, and investing with bitcoins. Show her how to make it and then she will understand. She will be familiar if you will include her on things you do in relation to bitcoins. She might as well willing to try and then eventually both of you will have an extra income through bitcoin.
