The thing is, people don't acknowledge the fact that women do trade. I don't know if people see it as a man's thing to trade and women ain't suppose to be involved. Like you said your female friend who knows more about crypto, some women has more knowledge in terms of crypto trading than men and they (women) are even doing better than men in Bitcoin trading. Women are good that's just the thing.
It's not that people doesn't want to acknowledge it, it's just that we actually do not really care if it is a man or a woman behind every trades or movement as there are no boundaries in crypto space and everyone is free to do their own thing as long as they are using the space and platform legally. Aside from that, I don't think that we still have the time to even think about the possible gender and sometimes, women can do a lot better than what men can do, sometimes.
