Even if you gave them your keys, I doubt that they will keep you alive. Cause they already got what they want, so what's the point of keeping you alive? Once they can have access to your Bitcoin, it means that they'll have enough money to protect themselves even if they kill you. They're bad guys so how can you trust them to keep you alive after giving them your Bitcoin? Also, if other trusted family members know your Bitcoin, and you got killed by not giving it to the kidnappers, they can target your family as well. In this kind of situation where money involves, you can't be sure that you'll be safe even after giving them what they want.
The best thing to keep you and your Bitcoin safe is to keep it private. The bigger the amount, the more private you should be. No matter if it's a relative or a close friend.
Yeah, I think you brought some good points.
If they are evil, they'll kill you anyway. But in a hipotetical scenario where you could choose, maybe getting out alive would be a better option.
That's the main point of the discussion, what would you choose then? since you just repeated it. What's best is to just give it to them if you really value your life 'coz no one would really be making use of it if ever you die due to them heartless. You won't also bring your assets to afterlife therefore no valid reason will be enough to validate and support the claim of those who will choose not to. It is a life or death situation and it would be okay choosing your life over the consequences of them getting what you've work out with. It will just be illogical being 'tough' and eventually dying because of 'money'; give it up and just invest again or take a break from this industry. According to my mentor, once you finally reached an amount money, you will always find a way to again be back into it and reach it again or even cross it.
It would be indeed unfair and frustrating but always choose to live 'coz life means another chance to be back on your feet. Let's say maybe it would be tiring to again be back to zero but what's a better choice then? Be tough and still avoid them to run with it or to just know that money will still be money, which is something you will to purchase.
