If the average rise of difficulty for the next 12 months is 30%, you can get your investment return if the price per GH is 0.089

Like he says, I WILL make roi..it is just a matter of time. But I am pretty sure the share price will be much lower by then.. how ever, I have gotten my 4 btc back and might sell shares for half or someth.
When did you buy? If you bought 1 GH/s almost a month ago then you have mined less than 0.113, but it cost you 0.19 BTC (or more).
I'm not saying everyone is guaranteed to lose money. It depends on the price you pay and what happens to the difficulty. The current price is down to about 0.134 BTC and that is still too high.
Speaking of difficulty... The difficulty jumped by 40% today, and HashFast is shipping their terahash miners in a few weeks.
He will, he doesnt pay elecricity and hosting fee.
Maybe it will take 3 months or 24 months but he will...

In theory, that is not necessarily true, and it is possible that he will not get his money back, even if he mines forever. It depends on how much he paid and how fast the difficulty rises and whether or not it stops rising.
In reality, he will break even, but it very unlikely that it will be in 3 months. 24 months is possible, but it could be 100 years, too. He could also get all his money back if bitcoins become worthless.
Do the math.

You'd be very lucky to sell your shares for 1/2 of what you paid for them.
I think the concept here is:
1. buy GHS
2. mine using GHS
3. sell GHS for slightly less than what you bought it for - as long as what you mined in the mean time covers the difference - profit.

#3 is where the concept fails. It can only succeed if the cost of the GH/s is lower than the amount that it mines.
However, why would the operator sell you the mined bitcoins for less than their value? There might be a legitimate reason, such as it could be a kind of loan -- you pay 0.15 BTC for 1 GH/s upfront and you get 0.185 BTC back over time. There are more efficient ways of borrowing money, though.
Anyway, that doesn't matter right now because if you are paying 0.21 BTC for a GH/s, you are paying more for the GH/s than it will ever mine. This is a very common newbie mistake. Most are too excited and in too much of a hurry to take the time to look at the numbers.
I agree, obviously you're buying something which price can only go down. And nowadays it's 30 percent in around 12 days so not a good deal

Unless cex.io goes bankrupt

I bought ghs worth 4 btc 5 days ago, they have mined almost 0.4 btc now so works nice indeed
So, you have 10% of your investment so back far. Do you really think you will get back the full 4 btw?

Nobody is selling chips.
What's happening why the chip price isn't moving? Still stuck at BTC1.67.
Price dropped like crazy today. 1 GH for about .14 BTC.
CLoud mining...cloud mining... wasn't Lando Calrissian into that?
Hahahaha - it wasn't even worth explaining to my wife why I laughed at that

Looks like pricing for a GH dropped to .18ish now
Still to high
Still to high
Cool, thanks for the explanation and calculation. I may have missed this, but where does 7040691 come from?
1000000000 x 10 x 60 x 65535 / 248 x 2016 x 25 = 7040691
Here are where those numbers come from:
1000000000 x 10 x 60 is the expected number of hashes per block (per GH/s)
65535 / 248 x D is the probability of finding a block
2016 is the number of blocks per period
25 is the block reward
Look at cex.io right now. You can buy 1 GH/s for 0.2125 BTC, but 1 GH/s will never mine more than 0.1850 BTC (assuming an average difficulty increase of 20%).
Even assuming that cex.io is legitimate, why would anyone pay 0.2125 BTC to mine 0.1850 BTC?
I don't think this business model will ever work simply because there is no reason for cex.io to mine bitcoins for someone else when they could make more money by mining for themselves.
I've also done some math when first saw this site, it doesn't seem to be a good deal...Even assuming that cex.io is legitimate, why would anyone pay 0.2125 BTC to mine 0.1850 BTC?

There is a quick way to estimate what a hash rate is worth:
Use this formula: VALUE = H * 7040691 / D / R, where
H = your hash rate in GH/s
D = current difficulty
R = average increase in difficulty each period for the next several months
For the last 8 months, R has been about 0.30 (30%), but that can't continue much longer. I predict R to be about 0.20 (20%) over the next several months. That's how I get a value of 0.185 BTC per GH/s. Others believe it will be much higher and miners seem to think it will be a little lower.
This calculation also doesn't include fees and expenses.
