Motivating women's is not so difficult if you ask me because you can just setup some online web stores that are selling clothes for woman and accepting the bitcoin.
I think if you do your marketing it will attract woman without any doubts and they will also look into the bitcoin itself.
Motivating women is very difficult thing to do as they will only follow that they feel good and if they find bitcoin is boring then they will never try to use it as a mode of payment.
Women won't enter bitcoin for the mode of payment. If they truly understand the earning methods sure they'll come to bitcoin and help more women adopt bitcoin.
