The tendency to show off bitcoin because most of them were poor the previous day so they are aggressive, not those who have been rich for a long time because I believe they are more private.
It is possible, and I think it is very possible. The nouveau riche are more likely to show off than the real rich, their reasons will vary but of course these kinds of things are never good. Some do it to prove to others that they are capable or successful, but unknowingly it only creates unforeseen risks.
Especially in the crypto space, everyone is expected to take good care of their financial privacy. Create a sense of security for yourself by maintaining financial privacy, and thus you will sleep better without having to think about the threats that lurk you. But if not, you may have to hire some bodyguard to provide that sense of security if you have a lot of assets in crypto.
