Sending Bitcoin to someone to trust is as good as keeping Bitcoin on centralized exchanges. I might as well as pick exchange over giving Bitcoin that is tempting as gold to another person. I'm not sure if I have a develop mind to even give Bitcoin to a friend because all of them I know are going to use their problem as excuse to finish everything on the market sell. I'm not sure if I'm the only person that doesn't have the balls to support this advice.
It's not right to compare a person to centralized exchanges. When I mentioned someone you trust, I meant someone you have a blood bond with. Even your best friend can one day turn into your enemy but family is different. Of course, not everyone grows up in the same kind of family environment and people's sense of trust can vary. I understand that. Everyone has someone they can trust, but who that is will differ for each person. If there really is no one, then that person already has bigger battles to fight in life than just keeping his Bitcoin safe.

It was called Cold Wallet and yes it is what you think it is about. Crypto heist!
Seems interesting. I'd like to check that out when I have free time.
