You are so rude? I'm not a girl but this is what I think...
Who are you to decide that girls do not belong here? Nowadays, a girl can also do what a guy can do, and sexuality isn't now the basis for us to be accepted, and so all people are accepted here or in trading. And I don't believe that girls always rely on their emotions and on their own intuitions, some of them, or almost all of them nowadays is unlike what you think. And I think, girls are almost half of bitcointalk community and a crypto-users much longer than me. I don't have a proper assumption on this matter, but I guess there are a lot them here hiding on different identity.
