Everything we do in this crypto space amount to security,first we should be security concious.Before you think of disclosing your private key incase of your dismissal it should be someone you trust most,it could be your wife,child or your close relation.Like let me speak for myself,every member of my nuclear family knows I'm into bitcoin investment,but I haven't disclosed my private key to any of my family member, it's not like I don't have any of my family member I trust but I'm always positive,how would I sow and not reap I'll definitely reap from my holding so I'll say Op always learn to be positive.
