Bitcoin Babe is legit, she is an Australian bitcoin trader.
She is really good at marketing herself, and she has used it too both make lots of money through selling bitcoin and also bring some attention to bitcoin.
Yeah, she uses her female allure to get sales, but who cares? She's good at it, and providing a good service, for people who need bitcoin.
After reading that interview I can sympathize with her, she is a fine girl. It is just annoying that she is convinced that bitcoin world is full of women and they are hidden somewhere and men are blind to see them,
that butter analogy she mention was really not good example. Every research of bitcoin community shows that this world is indeed dominated by men - by huge margin.
Maybe she know some girls who like bitcoin like her, but that is it.
