It'd be trivial for Bezos to take out a loan for a ransom to buy crypto in a new account, and then transfer it to another crypto account.
The extremely wealthy like Bezos have contingency plans and systems for this situation.
I’m assuming it wouldn’t be Bezos himself doing it. You would contact his employees and tell them to get you the crypto if they want him back.
Yes. That's the point, the ideal target is one that doesn't have contingency plans, not someone who has crypto.
