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.
no one can guarantee our security in investing other than ourselves. we must be able to set boundaries for what we convey regarding our crypto activities to other people even if it is our own family.
even though someone is still our family but we also have to understand how that person's attitude and behavior. There have been many cases of how a family deceived their own family.
please keep all our information private and never be too arrogant to tell about our success even to the point of sharing our personal information.
