Many girls in my own area wouldn't want BTC as a present on any event but the one's that actually know the value like yours will really appreciate it. I would like to say you did well and thats because the person you gifted knows it value and now my only curiosity is what she is gonna do with this gift like, would it be a start for her to start saving up BTC as an investment plan ?Or she would just sell it off in the exchange and use it as fiat and get something because Ladies are fund of wanting flashy things.
Bitcoin are absolutely worthless to those who don't know how high their market value is. So I don't think there's much point in giving bitcoin as a gift for whatever reason without explaining what bitcoin is and telling them how much it's selling for. Gold makes a lot more sense to give as a gift, but if they know about bitcoin and its value then of course you can gift them bitcoin instead of gold.
My moms is much more likely to choose gold as a gift than bitcoin. Of course that's because my mom doesn't know what bitcoin is and how high it sells for. But when I tell the value and how to sell it, then of course he will receive bitcoins as a gift with pleasure. The same would be true for everyone else, of course.
