You haven't explain why he and his family should be anymore paranoid by fear than any other moderately wealthy people. Why don't all your mafia people just watch CNBC?

"$400m" is not moderately wealthy, it's extremely wealthy.

Most moderately or even extremely wealthy people are obscure. One of the wealthiest people I've worked for had a saying: "it's good to be wealthy but not famous." He dressed like a slob, drove a generic Japanese car, lived in a moderate house but in Los Altos (i.e., given the money he went for a safer location as opposed to a gigantic house), and so forth... He never once talked about finance issues despite being involved in angel investments, exits, etc... Most importantly, you'd never see his name in a press release much less in a newspaper story (except once I think, where he was referred to as an engineer as opposed to his actual title).

However, Dorian Nakomoto's situation is far worse in that he's perceived as wealthy, but actually isn't: so he can't afford security, lawyers, a gated house (remember, he went through foreclosure -- he can barely afford a house at all!), and so on forth... He's sixty five years old, his mother is 90. He can't run, he's post-stroke so he likely won't be able defend himself even with a firearm. He also has much more at stake than others: he can't simply hand the home invaders or extortionists the money if, e.g., one of his relatives is kidnapped. Is this so hard to understand? Do you personally hate bitcoin so much that you're willing to be an apologist for endangerment of someone who isn't even involved in bitcoin?
