I think you might be right.

Are you saying the 69,000 wasn't a sale, just moving bitcoins around?

Yep, entirely possible that they had a cold storage server that is being replaced so they transferred to a new cold storage server.

Definitely a Silk Road wallet.



Most of that BTC came from http://blockchain.info/fb/1bbqjk

I thought that too, then I thought about the aircraft carrier thing too.
wouldn't either transaction kind of fuck up the economy?
all the guys watching Listen To Bitcoin and see this ginormous bubble and panic sell!
and why would they store that much in one wallet? how much Btc does Mtgox hold?

No one sold any coins, they are all still in that wallet still and it was merely the merger of two preexisting huge wallets (like the 7th and 20th largest to create the 3rd largest).  Examining the inflows from the earlier wallets seems to indicate merchant transactions (small and variable in size) rather then mining activity so either Gox or SR most likely.  But oddly the two early wallets only date back to mid 2012 which seems young for those two, so maybe someone newer like Satoshi-Dice.

i'm sure it's happened with the BTC amount, but i think
you need more than 1 mistyped character of an BTC address to fudge a transfer. correct me if i'm wrong?

There aren't 11 million buyers

Actually, there's a virus attack vector right there. Just always overwrite the clipboard with the attacker's address.

Always triple check your addresses!
