I was on Hashnest, in the UK at around 12:00pm GMT (04:00am Pacific Time) and bought a GH of the S4.
I bought it for 0.00028 BTC and sold for ~0.00029 BTC.
It seems the main problem with Hashnest's Market is TIME!
https://www.google.co.uk/?gws_rd=ssl#q=GMT+to+PDt seems relavent
At around 7-9am Pacific time the Hashnest price goes up, as there is a higher demand from the US.
At around 12pm Pacific time the Hashnest price goes back down to what it was!
Meaning that time is the second mot important component of a hashnest hash purchase!
