Why the heck does things even need to be "sexually balanced"? Sectors like technology has always been male dominant whereas healthcare and education has mostly been female dominant. Is there anything wrong about it? No. Let people work on their interests regardless of gender dominance.
There is nothing wrong with an all dominant male environment likewise it won't be such a bad idea to have more women in blockchain, I think the point is not about creating a balance but having women to be more involved, showing interest will also plays a huge role in btc adoption, women are known for shopping more than men, if we have enough women in blockchain and want to shop using btc don't you think it will have a significant effect!
