Banks are fortified and guarded for a reason. If you have money in bitcoin, it's only as secure as your person and whatever you use to access your crypto assets.

If you had a million in gold, would you leave it on your desk? Walk around with it on the street?

Brag about or show that gold off to somebody, as many in this story did, and you rapidly become a target.
