I stumbled upon an article on Bitcoin today, and did some calculations.
Apparently, each Bitcoin is worth 17.5$
Mining for Bitcoins is done in Mhash/s, and every 46
are worth 1$
Which means that 800 Mhash/s
(for one day) are worth 1 Bitcoin
As an example, an HD 6990 manages just around 800 Mhash/s
, with a 400w
peak power consumption.
Now the price of electricity ranges from 6 cents
for a Kw/h to 18 cents
, so let's take a median-high - 15 cents
x 15 cents
= 144 cents
Which equates to a Profit of 17.5$
per day, or 112$
per week, or 450$
Now you can scale that essentially up to any number (I assume).
Say you own two rigs with 8 HD 6990s, considering that the rest of the components run at idle.
(overclocked) = 7,200 Mhash/s
, with a typical power consumption of 2,400w
(let's say 2,800w
x 15 cents
= 1008 cents
Now for the profit. 7,200 Mhash/s
= 9 Bitcoins
, or 1,032$
per week, or 4,130$
per month, and 50,000$
So now I'm going to wait for someone to poke a hole in my plan to make 50,000$ a year without doing any more work than simple maintenance and upkeep, minus original funds for purchasing the components.
Again, this is just something I found interesting as I love calculations
