It's best not to discuss bitcoin with ANYONE. Even family. And that's not because I'm saying you can't trust them personally, but they might talk to their friends or coworkers about how their son or their nephew just made a fortune in bitcoin. It might get the wrong kind of people thinking.

And it's one of the issues that gives me pause for thought about a future world where everyone is "their own bank". Will we all need to live in fear of thugs breaking into our homes and demanding our hardware wallets and PIN codes?
