maybe women are lesser involved in cryptocurrency is it because women are having lots of responsibilities like doing the household chores and taking care of the kids rather than men that after their working hours they can have relax for a while....but let's not under estimate women today because now they are more competitive..
It is good feature of cryptocurrency/bitcoin that it is not banned for someone and everyone can easily join and earn money through bitcoin. It is reality that in our society women have a lot responsibilities and they have less time in their lives to participate in other extra activities but in the field of bitcoin women are found in enough quantity.
Women get appreciation of people and different societies being a bitcoiner. Shortly, I will say that cryptocurrency bitcoin is shield for women in society which is a good virtual activity for women earning.
