I think a successful bitcoin trader or miner will find it easy to invite a woman to the bitcoin community because you simply cannot argue with results.
Iam trader, Im miner but introduce bitcoin is not easy as you think, trying introduce to my friend not only female, male too, but it's very hard to make them interesting to use bitcoin, it's depending about hobby, work, etc. if they are not interesting with technology im sure he not want to know about bitcoin anymore.
