OK - sounds like we have a short-term opportunity (reduced selling fees) that makes this an even better possibility. So we are comparing selling a Jupiter (two workers in R6, total about 550-600GH/s) that is producing ~1 BTC every 2 days, for ~$20K. If $/BTC rises at approximately the Difficulty rise, it means that we would lose any income past the next 40 days, roughly. Correspondingly, we would capture (eliminate the uncertainty) effectively the next 40 days of income all at once.
Assuming this is a reasonably accurate description of the circumstances, I vote my 37 shares to sell.
Please, anyone, point out any misunderstandings or bad assumptions!

P.S. Does anyone know why the Saturn is offline?
