Glad to hear that most of them are intact. Why not move them to a wallet to prevent whomever has the private key get a hold of them and move them again when you get the rest of them? It will also be beneficial to have the addresses on OP. Do we have a richlist somewhere?
because moving such large amounts of coins and storing them in one place is very risky.
its better that they get the legal trust and multisig sorted out first before moving any of the coins.
