You put yourself at risk when you talk about your bitcoins, what you have, just like when you talk about your other success. Unless you are discussing bitcoins with people who you know own bitcoins, same amount as you or even more.

Jealousy can easily be germinated in someone you speak to about bitcoins, try not to water that evil seed by further sharing how much you own in btc to people who you may think pose no threat to you.

Keep things private, something not known by people cannot be stolen or destroyed.
