Most persons may say no but YES is the actual answer
In the ideal sense the dominance of crypto currencies by women is in great progress. Bitcoin is the most popular crypto currency and therefore a currency of such will be dominated either now or in the future.
Women engage in crypto currency transactions also like men do the reason you may feel they don't is because those that don't have not much idea about it.
I have seen many women who invest in bitcoin and also trade bitcoin, and many are getting associated with bitcoin as time counts. Some people thinks women are not much interested in cryptocurrency, well this can depend on the location where you come from. Another thing you should understand not all women can be able to bare the risk that is in cryptocurrency.
But from my own experience I know women engage in cryptocurrency, I have even met several women who have come to me that they want to learn crypto trading.
