I had seen posts of females here in bitcointalk. Not few. But not even more. Some. Maybe the "weak sex" have other interests in their life. Maybe their like more the hair saloons than the technology and bitcoins. Who knows? I have no data about this matter and to tell the truth have not seen not only females but even males to have interests for bitcoin in my known people. The only one who talk about bitcoin (sometime boring their who are with me) am only me. Being in such situation cannot tell that females are less interested about bitcoin compared to males. But your case talk clear. Unfortunately the ladies like more other kind of pleasures than bitcoin. But are such pleasures liked by females less enjoyable compared with our (males) desires about bitcoin? I must think well about the answer of this question.
