That final address with 344 coins in it has been active since August 2012. Interesting.
And 20btc were paid out from it to this address in Sep 2012

Taint analysis (I don't know what I'm doing) says 12% of incomings to the address came from mining Pool 'DeepBit'
https://deepbit.net/Ken says he was an early miner and the DeepBit coins were there from the start so this could well be Kens wallet. It could also be someone he paid? Can anyone else find out more?
Payment have been made from it to Nasty Fans, Bitcoinmalaysia, enmaku, Mysil2 and ASICMiner, plus hundreds of other addresses.
