I think a good way to motivate women to use Bitcoin would be to make advertising that is attractive to women and to get many women to advertise it and pay them for doing so. Women love advertising and are more likely to use a product or service after it has been widely advertised.
we just need to say them that they can do shopping with it and I think that is more then enough to motivate any women to start using bitcoin.
Yeah thats very good motivation to them but some i really see lot of gals today using and make competition to boys earning with bitcoin and mostly of them are housewife and only left home to take care of their babies, and i think the best motivation to show them and to see them how they can earn and show them your earnings and tell them that she can earn the same way to, by that they can surely be inspired to try using bitcoin.
