Before reading the replies to the OP my first thought was, Why do we need to know?
Nobody goes around posting what they own here on the forum and I dont know
anyone who has told me what they have in FIAT either.
There is no need to verify what any public listed company owns because being
publically listed they have a duty to publically notify their purchases.
I doubt too someone is disclosing his own wallet(s) but in case of Bitfinex, it would be nice to know who has control. 90k+ coins is a lot...like if they are "lost", seized or still in control of a criminal, would be interesting.
but you are right, we don't NEED to know but I asked because I want to know. A free choice
