Apparently he only accessed the wallet to update to the new address format. Interesting how it served for so long as a beautiful safe inaccessible by the government.
Imagine if ever he decided to dumped it once on the market I cant imagine how much impact it would cause it. Anything comes from silk road means it was from hacker or some guy who uses it on illegal stuff online. The bitcoin is pumping well inspite of current election status so this guy should probably waiting for a perfect timing to unload his bag. Everyone should be aware that anything can go sideways especially a wallet holder with that massive btc could dump any moment.
