I've learned the dangers of oversharing online, especially about Bitcoin. Silence is golden.
It comes from their own personal traits and characteristics. Some people always want to have private life and they don't mind to share personal information exclusively profit from investment or what they invest money in.
Some other people, in contrast, want to be recognized by the crowd and they share personal information that they believe can help them to be more recognizable, more famous. By this, they self-break their privacy and worse, can have danger in life.
I advise them to maintain their digital wallet as close as their actual wallet.
I don't really understand this advice that seems to be incorrect too.
Digital wallets can be custodial or non-custodial, open source or close source.
A good wallet to use is open source, non-custodial.
