I believe gender does not have anything to do with investment; as anyone or anybody should be able to make an investment at well. It is often seen that men engage more in either forex or crypto investments (reasons not yet known by me). So, it can be said for a fact that few women buy into Bitcoin.
I follow many crypto-girls on Twitter. I think they can be seen on other places as well. I believe there are more than just few
women in crypto-currencies. With time there will be more women in crypto-currencies, like in everything else, they come a bit late,
maybe it's a gentlemen rule to check first, is it safe.
I agree that gender does not have anything with investing. Before that was a mans job, with crypto-currencies girls will find
investing more interesting, and they can do it from home.
