Best price on dgex.com right now is 0.00000898. That's 111,358 NXT for 1 BTC.
I'll sell you 142,000 NXT for 1 BTC (~0.000007 per NXT)
As for escrow, I don't know. Maybe I could put it up on dgex and you could snipe it before someone else does?
Edit: Price on dgex.com just went up, but I'll be nice and stick to mine anyway.
