I'm not really sure if I personally see any barriers that are holding women back from joining the crypto community.
For the most part, I think that our community is pretty welcoming to all people, so maybe it's just that cryptocurrency doesn't really appeal to to women?
That said, I have a couple of female friends that are actively investing in crypto, so I don't think it's right to over-generalize too much...
The best thing you could do is just try to involve more of your friends, let them know what's interesting about crypto for you.
I'm also not a big fan of women-only or men-only channels, people of all gender/sex/orientation are welcome in the mainstream crypto channels anyway.
It is simply not in the line of interest for women. I find that most of them are not interested about it. Some get curious at first but lose interest because it's too "technical" for them. Bitcoin itself is not sexist. It's totally accessible to women as much as it is for men so there's no issue on that. It's just that women choose not to use it for themselves voluntarily due to lack of interest.
Well that's basically what I'm saying, except that there are still some women that are interested or could be interested in crypto.
Interest isn't something that's gained 'instantly', usually there are a few external factors that contribute to developing interest for something.
I don't want to turn this into a whole 'nature vs nurture' debate, but it would be short sighted to say that social factors play no role whatsoever.
