I don't think this topic fits in the Speculation board, i don't know where it even fits, maybe in beginners and help, maybe.
Maybe economics board will be more appropriate. However, I do not believe the story in OP. It is not connected. It is just what everyone has been saying; don't allow people know your holdings. He just made up a story from it and that's all.
Among my friends, I know how rich they are. This is what I also expect in every pair group. So, you wouldn't be surprised to know how much your rich friend invested in bitcoin. But then, the message is still valid. Not to know people know about your holdings.
