What if you had, let's say....5000 Bitcoins in your custody and suddenly someone demanded it as a ransom in exchange for someone very important to you, would you make the exchange?
depend on who it is?
i think if they know i have 5000 bitcoin in my wallet, he must be people that know or close to me.
i will give if it my family and i will track until i know who it is. or i will say i dont have much bitcoin if it my friend
