He hosted a crypto event from what I am reading here, the moment you're a speaker for such you basically put a tag on yourself.
You could blame some of the victims but let's assume a guy like Andreas Antonopoulos gets ambushed like this,  he hasn't flaunted his wealth at any point but everyone with a brain knows he must have a few dozen coins at least on his name, should we blame him for getting robbed also?

I don't like when living in fear and hiding in the shadows is becoming a a norm to keep you safe.
