Was there a raffle this month?
Also PBmining you need to update your main page. It still says minimum contract of 1gh/s when I think it is up to 4gh/s for minimum purchase. At least my slider will not go lower.
try zooming your screen...
He's right I just entered 1GH/s in the order and said it's Invalid Hashpower.
who wants to buy 1 GHS ? , be realistic..
1 ghs costs you not 0.0054 it costs 0.0054 + 0.0001 (transaction) + 0.00007777 = 0.00557777 BTC / GHS ---> 3.29 % higher of original ghs
But if you purchase 100 ghs
100 ghs costs 100*0.0054 + 0.0001 + 0.00007777 = 0.54017777 that means ----->>> 0.00540177 BTC/GHS ----> 0.03 % higher of the original ghs , exactly same enough.
So what we learned, try at least 10 ghs or more purchases..
Newbies that don't have that much and only want to try out cloud mining.
