Yes bitcoin needs all the genders.
Eventually it will be more good and more supportive for bitcoin ecosystem if more girls are adopting bitcoin.
When a men adopt bitcoin it may end up only with him. But whenever the women are adopting, it will grow at least to her family.
Not all men are like that the keeping bitcoin from himself I actually use bitcoin to support my family and it is great I am employed had a great job and earning bitcoin here in forum and faucets,
And you are right by saying that all genders are needed to keep the bitcoin ecosystem alive! but in my opinion there female using bitcoins are fewer than male using bitcoin!
Yes, all men are not like that. But I also feel women are very good in talking about any new technology. We can say women are very good in promoting bitcoin ecosystem then men. I wish bitcoin ecosystem have many women to promote it to have more new people to adopt bitcoin for daily life.
