3 months ago, one of the biggest Turkish exchange owner had kidnapped and forced to give private key of the cold wallet. Kidnappers stole 150 BTC. So this news is not the first physically stolen Bitcoins via force. I am sure there were some other robberies too.
Yep, kidnapping in order to knock out private keys is a very common practice nowadays. It has happened before, it'll happen again.
Yeah and that's unfortunate but i don't think that'll likely happen to normal traders like us since it would have to be really random for these criminals to pinpoint our identity. Owners of exchanges can have their information posted so they'll really be targets
