There are already many documented cases where people have been robbed and in some cases even killed because they have publicly confessed to have Bitcoin or any crypto. By behaving in this way, you are not only endangering yourself, but also your family, who can become the target of kidnappers, which has also already happened in at least one case.
I personally had more than a few people telling me exactely how many satoshi they had in their account and where. Something no one would ever do with their bank account.
This is some weird logic displacement in my mind. A lot of people are still thinking to BTC like they weren't real money.
Really weird logic, and I think the thing is mostly that people like to brag about something out of the ordinary in the sense that they want to look smart because they invested $xxx, and they turned that into a $xxxx amount in a very short time. Bitcoin is still not perceived as money, because if we turn around and look at where we can spend it, we will not see the BTC logo in too many stores (if there are any at all).
