That is wierd. Could you please wait till this weeks payouts and let me know if you still haven't received your payment by Monday.

So lets say I bought .01 BTC for GHS on CEX.IO. At the current rate of .075 BTC/GHS I would get .133 GHS or 133 MHASH. What time period would I get that hash rate for?

You need to share tips about btc first at newbie thread

Bitcoins is best, you could only buy 2 USB block erupters for $100

Please don't invest in mining without first learning how to compute your expected return. Too many newbies blindly invest and end up losing money.

For example, on cex.io, a popular cloud mining site, 1 GH/s costs 0.074 BTC, but 1 GH/s will never mine more than 0.05 BTC. For every GH/s you buy on that site at that price, you will lose up to 0.024 BTC.

I took a look at the cex.io site and the numbers seemed very bad.
Maybe I read them wrong?
Can you help here? It says GH/BTC 0.0747 what does this mean? 0.0747 GH/s for one bitcoin or 0.0747 bit coins for 1 GH/s?

If it is the former then $10k would get you 74 MH/s which is just pathetic. You would end up just losing money.

The latter on the other hand equates to about 13GH/s per bitcoin which makes much more sense. Hmmm. I might actually consider this. What I don't understand is how the maintenance fee works. I expect hat after about three to four  months you would want to  pull out your money and mined coins as difficulty skyrockets but I'm not entirely sure of the math related to the depreciation wrt maintenance and pool fees. The calculator just says 3% for each. IS that monthly/ daily does it compound?

I think i'll just email those guys.

And lastly, why don't they just mine the damn thing themselves? I can't imagine they have idle hardware sitting there waiting for someone to pay for CPU/ASIC time.

I kind of like CEX.IO.  It was a bit confusing when I first came across it as to exactly what they were offering.  I just signed up this week and transferred in enough NMC to get started mining with 3.0 GH/s.  While that will not get me a lot of BTC, I do not have to worry about keeping all the BTC miners running in the house.  I have about 60 GH/s in Butterfly labs mining equipment running at the house.  With the high prices they are bringing on EBay right now, it almost seems more cost effective to sell them all there and put the $$$ into GH/s on CEX.IO and not worry about the electric bill or hot room any more.
