Looks like it's a made story by you because no one will be confused if his kid get kidnapped and the kidnapper demand money and the money you have. In this situation everyone will sell his Bitcoin if he has the amount.Because you can earn money back again but you may not get your kid safely if your kid gets kidnapped. This thread is looking like so poor quality to me and this question doesn't make any sense to me.
Some persons are stingy,and it affects them to their family.How can one be stingy to his family,what I see in this case is that,if he has Bitcoin,and his child is kidnapped,he will contemplate on whether to sell his Bitcoin or not,and these types of people are very hard-hearted. When you have the means of helping someone and you refuse to help,it's bad to you.I don't blame him for making this kind of thread anyway,because I see that some persons lack what to post,and it result them in making threads that does not interest people to comment on.I know it isn't easy to make post,and I won't discourage him,rather I will encourage him to put more effort in the kind of thread he makes.
