"I've done a bit of blockchain exploring.
The block in question where all the bitcoin days were destroyed is this one:
https://blockchain.info/block/00000000000000048445e1220a78e53de15c74160ffbe4dad0b52099560e045f
About 120,000 btc were moved. There are many transactions in this block in the 4,500-5,000 btc range. I followed the source addresses back in time. The ones I've looked at all trace their heritage to this monstrous transaction from 27 January 2011:
https://blockchain.info/tx/8f8210694d3631a88ff410c573d80caf57db1d8af397bd47687aa4e4c1802464
A single transaction moved 400,000 btc to a single address; this one:
https://blockchain.info/address/1AYtnRppWM7tWQaVLpm7TvcHKrjKxgCRvX
So whoever made the transaction yesterday had 400,000 btc in a single address in 2011. If it isn't Satoshi, who the hell is it?
Note that that 1AY... address had some transactions on 26 November this year; shortly before the ATH on 28 November. A huge whale, perhaps the biggest single holder of btc in existence, is stirring. The question is, why?
EDIT: 400,000 btc in early 2011 was almost 10% of all btc in existence. In a single address. Wow."
I saw that earlier and my first thought was satoshi as well.
