Why is this so much higher than your other group buys? $130 for 40GHS plus some kind of group ownership of the hardware is much more appealing than this. Comparing to Cex.io is only valid if I can mine with this for an hour and then sell it for higher, which I can do with Cex.io all the time. Also, Cex.io is perpetual meaning that it doesn't cease to have any value after a year. Still, Cex.io makes absolutely no financial sense as a mining operation only.

Anyway, I'm just trying to understand what this significant premium on GHS buys me over your standard group buys.

Thanks.
