Why do people think TERA is a woman?  IIRC, there was just one forum member who started calling TERA a 'she', TERA never corrected (which I understand if you care about opsec), and everybody just started taking over this habit.  Not saying she cannot be a woman, but there is like zero indication about his/her gender.  If anything, I would think that traders that are early adopters of bitcoin have a higher likelihood of being male (though undoubtedly some women are also early adopters and/or trader).
