Recently, I came to read this news
https://protos.com/spanish-police-rescue-crypto-investor-kidnapped-on-holiday/The first thing that came to my mind after reading this was that one should not talk about his crypto investments with strangers or friends as it can pose various risks. If you are active on forums like bitcointalk and involved in trades, you should not give information which can help others relate to your identity.
This is exactly why I don't talk about crypto even with my friends. I mean, I trust them, but they might talk about it with someone else, and they will talk about it with someone else and you don't know who can hear it and decide to steal it... I think that you shouldn't talk about not just Bitcoin, but about your money at all with others, unless you have to because of work or if it's your wife or long-time girlfriend.
