I said to my girlfriend to go to amazon shop and buy something with Bitcoin and then she trying to buy some nice shoes.
Girls like to waste money no matter bitcoin or dollars/cash. The main motivation is amount of money. It's not only about womens, everybody loves money and also everybody loves waste money.
It is not like that i can show you some woman who are very keen in this Bitcoin and Alt coin, just somedays back i got introduced to a user from yobit and she got so many knowledge about alt coins and she is in this field for more than 2 yrs and they have a group where they are doing high trading in Altcoins in many exchanges.
so dont underestimate the girls power. it is true that if more girls start to use bitcoins they will be more fast improvement in bitcoins.
