Then his loan on BF for 2 000 btc was as far as i understand partly used to pay back people that first loaned him the 900 btc that he was short and i think a large part of the remaining around 1100 btc was probably invested in btcstocks, when the two bitcoin stock exchanges btct.co and bitfunder had to close business many of his stocks lost a lot of value as i understand it, a 500-600 btc(50/60%) loss i think it was that graet himself mentioned, what happened to the remaining around 500 btc stock values after the initial big drop i have no ide.
His miningpool havent come back to the levels it was at back in the earlier mining days but it was doing pretty good for the months aug and sept this year when avalon pointed 1/2 there miners at his pools but it looks like avalon has left his pool some weeks ago, no ide why that is the case.
The lower price of bitcoin that we have seen recently should of course be a great time for graet to move some IRL assets into BTC if he wants to clear a large part of his btcloan debt, the mentioned 200 000 dollars would have bought around 667 BTC @ 300 usd/btc and if he had a buyorder at btc-e back earlier this year when it dropped down to even lower level he could possibly have BTC assets of well over 1000 btc, maby even over 1500 btc(if he managed to save the remaining 500 btc stockassets from btct.co/Bitfunder) by now, but i guess its a matter on how he have prioriticed things and what actions he has taken to fix his BTC debt problem.
