I see a closing price of 0.0236BTC/GHs, which ran far below my expectations, anyway turns out a purely mining January 2014 GHs holder would now be seriously out of luck and best off realizing losses & quit ASAP.
This week it sucks! It dropped bellow my predicted value. I bought too early at 0.0220 and now we are at 0.0205. Shitty... I've to wait for mining profit just to quit with zero. 
That's unlucky, hope you got out in time to take another entry spot.
Currenct price states 0.0156 BTC/GHs... the 0.02 BTC/GHs barrier fell on very high volume.
Maintenance fee increased to : 13.67% (!)
A purely mining guy from the Jan 2014 scenario would have had to sell @ 0.031 BTC/GHs in 2 weeks just to get out with a 0 (actually more than ~0.035 due to the 5-fold increased fees in the meantime).
Far over 50% of the investment lost in about 2 months, that's quite something.
That should answer (once and for all) any questions about mining profitability @ cex.io.
The traders I wish the best of luck.
