I think motivating them will be a little hard to something which they do not know, but I think motivating them to the bitcoin, a currency, will not be harder as nowadays females like money they love it and love to go for shopping with a good amount of money so when they are provided with bitcoins and are redirected to some stores which accept bitcoin for their payment.
There must be more shops and stores that accept bitcoin as payment. Women love shopping, but they love it more when they can go to a shop, and try on new clothes, make up, bags and what have you. If there are more shops that start to accept bitcoin, women who really love shopping would find the convenience of having bitcoin in their favor.
