I understand that some members have no reason to hide their Bitcoin holdings, but I see no reason to make it public either. For example, I have nothing to hide, but I still want to exercise my right to privacy. No one needs to know how many Bitcoins I have in my possession, just as no one needs to know how much money I have in the bank or in a private safe.

As for the mods and admins, I believe most of them are very well aware of how to keep their Bitcoin holdings safe, and I doubt they have made their cold store addresses public.
