I have not calculated anything. Maybe it's just worth 1% of IPO price or even less. What Do I know. I don't follow the mining market any more that closley. What is your estimate based on e.g. gigahash.io share prices?

There are a number of ways to calculate its value.

FACTS:

There is 150 TH/s left of equipment that is hashing.

The data center lease is a liability (because it is paid in a currency that miners do not produce).

There are 13,117,745 shares outstanding.

SELL THE ASSETS:

In the market you could probably sell the machines for $2 per GH/s at best. That means $300,000 or 690 BTC. But, you also have the coins mined so add those in too, I think there were 600. BUT, you likely would have to pay off the datacenter for the lease so that would cost some money. But, BEST case you all would get 1290 / 13,117,745 = 0.000098 BTC per share.

What would someone pay based on the income stream?

150TH/s in a 57,150 TH/s market has potential to produce 9.5 btc per day (at the current difficulty).

Or, 285 per month. About $125,000 at current prices ($435). Now I believe you owe the data center $22,000 (50.5 BTC) each month.

So, there is really only about $100,000 to go around IF difficulty did not increase. If you could find someone stupid you could probably get 1,400 BTC for this whole company. They would have to be a huge gambler though (or just naive about the market).

But difficulty does increase. So, let's look a month out. By June 1, we will have three more difficulty changes, Even if these are small and stay at 10%, we will have 8 billion X 1.1 x 1.1 x 1.1 = 10,648,000,000 as the new difficulty June 1. That is 76,000 PH/s. So, in the FIRST week of June ICEDRILL (if they find a lucky pool) will produce 150 / 76,000 X 3600 = 7.1 BTC per day for a week. Then 6.5 for 11 days, and then 5.9 for the next 11 days.... So, in June ICEDRILL would likely only get 195 bitcoin. BUT, they will still owe the data center the same 50.5 btc (assuming btc prices do not move) so they will only have for dividends 144.5 BTC or about $63,000.

Do you see the problem here? You are making less coins each month, but you have a fixed liability to the data center. If BTC prices do not rise soon, you will be mining just enough to pay your data center fee in around 6 months. If BTC falls to $200, you will not make it through the summer.
