First I'm quite skeptical that all btc gonna go to a single person/organization..! If someone can pls confirm that. because what I heard is that they are not gonna bid for all 29,656.51306529 bitcoins at once.
Ok lets take the case of if that happens and a persons succeeds in acquiring all 30kbtc from auction , I won't call it a wise decision to dump all the coins at once. seems totally absurd to me, dumping them according to market and necessity would be wiser.
One other thing that matters is who wins the auction, as the list is already leaked, there are few good names in it.[although they all are in for money]
