One thing that bitcoiners needs to know is "keep your source of income a secret and private matter", something that should be to yourself alone, let people see that you are not poor, you're making income somehow but don't don't how or where it's coming from. That's how a bitcoiner ought to live.
Kidnappers have two options in mind, either to get what they want or kill you if you're preventing them from getting what they want. So in that situation giving out your seed phrase is what should be the best reasonable thing to do. It's when there's life that there will be hope to make money. The motivation should be that, if you can make that amount then you can also make more of that if you're alive.
I see many on social media who openly declare themselves Bitcoin lords and queens, I laugh
, what OP said might be just a mere conversation but it actually happens in real life. People actually believe Bitcoin holders are multi millionaires when in real sense, some are actually struggling to make profits. I won't really blame those who think this way about Bitcoin holders, afterall, you gave them this impression about you. No one will attack or harass you if you do not give them a reason to do so. People need to learn how to keep certain information about their personal lives private, carelessness will only expose them to more danger.
If for any reason I am being attacked and my life is at stake, why should I struggle with them? I will rather fight to stay alive than fight to protect my wallet. Life has no duplicate you know, Bitcoins lost can always be recovered.
