New technologies will create new ways to rob, steal and exploit people. Bitcoin is nothing more that digital money.
Gunpoint bitcoin robbery still shocks people because it is 'bitcoin' that has been stolen, no one would bat an eye when it was simply $2k paper money robbery.
Just remember folks, if you carry around a smartphone with a large amount of BTC, you can be targeted in a similar way.
Well there was nothing innovative in this robbery, it's not like they picked some random person and told him to take his smartphone and send them Bitcoins, they setup a meeting for the sake of exchanging Bitcoins and the victim must have chose the place pretty poorly. I think we are still very far from days when robbers will be assuming that their targets have cryptocurrency on their devices, and even if they would, it's very inconvenient for them, since they can't quickly check it. They might start stealing mobile devices and try to crack wallets, but if someone has backups, they can move funds faster than thieves can crack stolen device.
