I really don't understand why there are people who can do things like that. It's just, where's their humanity? Technology wise, they seem to know very much about crypto. Why they can't just use their intelligence on worthwhile things without having to degrade and hurt people knowing that others worked hard for it? *sigh*
Seems like money, really, is the root of all evil. We should always be on guard on every circumstances that we may encounter. And I hope that those people will soon realize that their actions are unjust. Hope they still have even the slightest conscience.
A lot of these robberies are actually committed by boneheads who are trying to steal cash during a face-to-face transaction. Hence, their stupidity will reach unbelievable depths in some cases. So, one lesson to learn from this is to avoid doing major transactions in places where you can be vulnerable - and yes, a weapon can be handy.
Apart from the report of the stolen bitcoin ATM containing 2,000, I don't think there is any other that has to do with face to face transactions. Most of the crime are carried out using an insider or working with information. Bitcoin/cryptocurrency is anonymous and at that it hard to no who is a big holder so criminals don't work alone they get information from close persons before they attack they victims.
