I love Bitcoin but not more than my family loved ones. Of course the person you quoted here should rescue his daughter by selling bitcoins if needed. But he must do this with the help of the police. And it is not possible to say whether this incident is real or not. If such an incident happened, I think it would have been covered by any news or media. I have a slight doubt that you made this incident a post here. But anyway if it happens to me I will definitely sell my bitcoins at any moment to rescue my daughter under any circumstances. Because I love my daughter very much. I can never lose my daughter. I will earn a lot of money in the future. But if I lose my daughter, I will never get her back.
