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?
This is terrible advice, what if you die all of a sudden. Now your coins are forever lost as your family has no way to access them.
People store valuable items in their houses and the majority of people don't fall victim to home invasion. There is no reason to live in fear because a few robberies make the news.
Well, I would revise that slightly to perhaps permit knowledge with a significant other, or in the absence of that, another family member you can trust well. But make sure that they're smart about it and that they're not spreading information to other people. Yes, maybe that sounds too cautious. But we all need to be careful with our safety. And I say that because bitcoin is essentially digital cash. It is well known to law enforcement that people who keep large sums of cash at home are common targets of theft. For instance, people who sell drugs or run home casinos put themselves at high risk. Also people who recently won a state lottery.
I think crimes like this against BTC owners will increase in the coming years, unfortunately. Be safe.
