^^^ But that's the point. You can't easily steal someone else's bitcoins, even if you shoot the guy dead.

But well we know that there are cases with torturing to get bitcoins. And unfortunately no one knows that you don't have millions, they will torture for long expecting to get sometimes even what you don't have. So I'd prefer that others know that I don't have that much! But if I will go to the meetings just to say that I'm a beggar that would be suspicious: who will believe the one attending bitcoin meetings and saying he has nothing?
There are definitely cases in which bitcoin holders were targeted for their bitcoin holdings. That's why in my opinion, its never safe to disclose your finances or your exact bitcoin holdings to anyone so someone out there wont be motivated to come and try to get their hands on my finances.
If at any point in time, Im invited to go for a Bitcoin conference or a meeting of some sort, I wouldnt disclose my finances to anyone. Ill probably come on as a newbie with no investment but eager to learn. Its better and safer to keep everyone guessing.
