There are more women in cryptocurrency trading than you thought is a boys club. I personally witness women that buy and sell crypto in large quantities.
Definitely there are no discrimination in bitcoin. But why do they say that there are no women here? I guess because because investing here means investing also time. As we all know, man has all the time in this world for themselves and their work while most women are the homemakers and we have all the responsibility to keep the home and family orderly so it means we have less time to work on bitcoin. But then that was before, time management can be applied and a lot of help from helpers and family members are available that is why we are here.
