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.
They will start to love bitcoin also.
Independent women who wants to earn on their own for living will surely start using bitcoin if they are made aware about it, but it doesn't go same with other women who are already rich.
That's true, so its better to teach those women rather than one who is rich. Also if they understand the initial part and need for bitcoin, possibly they themselves will start learning through various sources.
