Is it just me or have some people been watching too many movies these days? Are there ANY examples of this having happened in the US, with BitCoin, ever?

People do this to drug dealers every single day. It happens so often that it is rarely considered newsworthy enough for even local newspapers.

There are not really any other good examples of large amounts of wealth being stored in physically convenient forms in people's homes.

Like people forced to give their riches at gunpoint ? Just watch the news ...

There have been examples with much less liquid digital goods, like in-game items.

It's unlikely, but it's really not that implausible. It doesn't take much sophistication to rob/coerce someone at gunpoint.

So someone can approach any ex secret military contractor in USA and get anything he/she wants just as simple as that? Isn't it like a security breach?
