I was listening to a news that one of the relatives of a person kidnapped him and asked him for bitcoin in ransom. This happened because that person showed his bitcoin holdings to many of his relatives and news spread among them that he has lot of money invested in crypto. Though, finally funds were recovered from that guy but he could have even lost his life in the whole scenario. Thus, you should be careful with disclosing about your bitcoin holdings to everyone.
Well, I agree with that. we don't know bad people may be around us, and we don't realize their goals. However, showing off bitcoins or even anything valuable that we own in public, would be very risky. Not only bad people, but people who are ready to hack your device will also look for information about these assets. So, I think things like that need to have privacy.
