Using bitcoin isnt a complicated thing, we could spend it for anything. Maybe you mean its too complicated to explain bitcoin completely for women, even for men.
i don`t think it`s so easy to buy something with bitcoin like you can buy with cash
If you mean there is not many shop accepting bitcoin, then I will say yes, its not easy to use bitcoin to buy something. But in country where bitcoin developing rapidly, its not a problem.
Most of the men use Bitcoin for a variety of reasons, such as protection from inflation, anonymity, ease of storage.etc. These factors are not important for women. So there is less incentive for them to use Bitcoin or any other crypo-currency. That said, the best way to get them using Bitcoins will be to give them some coins for free.
I think most of men using bitcoin for gambling, and I guess there are many women gamblers out there. Inflation, trading, etc is just for investor and trader.
