due to the fact all cloud mining services have turned out to be ponzis and such, I see it very difficult for a sale. you could ROI in 3 months if nothing changes with price and difficulty.
I see you got a bid for 2 BTC if i were you and I needed the btc right away I would take it.
but at the same time there are 6Th worth of power there,
Question can you point it to a pool or your choose or must it be set to bitcoin? if its the latter i might be interested.
