Well i already tried it in my wife instead of making a profit she gamble it in gambling casino online because she expecting to win big..
and they are interested in bitcoin because they know that its money i can withdraw it into fiat and use it to buy anything.
Lol I think she just became interested when you were saying that it could be used in online casino. You could tell her too that bitcoin can be used to transact her money into anywhere without big fee. I think women will love it.
