Cool so... someone with an eruptor could mine about 4700 ZET between now and the next difficulty increase (21 days?)
and then a further 3122 ZET in the next 28 days after that, and then 1561 ZET in the 28 days after that?
Yeah, now that it's on Coinchoose, the profitability of mining ZET will always be about the same as mining BTC. With lots of statistical noise obviously because of its quick re target, and profitability jumpers. I just keep the ZET I mine and believe it'll be worth more in the future. It's worked thus far.
EDIT: Oh, I think you might be referring to the reward halving. Yes, if the difficulty remained exactly the same. But the difficulty will keep changing in accordance to profitability.
