Amateur BitCoin-mining — is the game worth the candle?

There are several conventional machines (something like Core 2 Duo) Xeon processors and underloaded server in the rack. All without a GPU. In principle it is possible for the night to put thresh (the same server is not desirable to panting heavily in the room, people noise will interfere). Appeared logical (not penetrating) the idea to put thresh bitcoins. Question — a couple of hundred bucks on beer at least a month so you can squeeze?

Now makes sense only GPU.

I would like to know, is there any point in mining on the GPU servers and Amazon? aws.amazon.com/ec2/#instance

I think that has no meaning. I have not followed the development of bitcoin, but I minil two years ago. Then, for 2 months of continuous mining, I didn't remember how much of bitcoins, but a little more than 8 thousand rubles. Sold something around $ 20 per bitcoin, ie about 14 bitcoins. Mainil on 5850, the speed was about 450 megahexe per second.

can be roughly calculated.
\r
now on the pool — mining.bitcoin.cz common speed — 2000 GHash/Sec
\r
and judging by the statistics, they generated a block about once per hour. 1 block = 50 bitcoins, let's assume$ 10 per bitcoin, ie$ 500 per hour
\r
it turns out
2000 Ghash/sec ~ 12000$/day
1 Ghash/sec ~ 6$/day
1 Mhash/sec ~ 0.005$/day
\r
the Amazon GPU instance with 2.1 worth$.hour, there are 2 x NVIDIA Tesla “Fermi” M2050 GPUs
CUDA mining is bad, but craftsmen say, if drank with a file — somewhere 500 Mhash/sec from the card to squeeze.
we assume that the two can soak 1 Ghash/sec
\r
it turns out that Amazon will give up to 50 and get 6
\r
unprofitable.
\r
iron can be found here:
\ren.bitcoin.it/wiki/Mining_hardware_comparison
\r
the "cool" core 2 duo that is in the table (Core 2 Duo E7300) yields 8 Mhash/sec ie somewhere 0.04$ per day
\r
IMHO, electricity is more expensive.

No "couple hundred bucks" a month will not be a dead idea. Previously off the top Radeon, which was taken under mining, now seems to have and it doesn't pay. Mining using the CPU generally gives a miserable performance, compared to videgame.

You can connect to bitcoin pool, but correctly suggests, the game has long been not worth the candle. At the end of the year is expected another increase of complexity, since it will provide for 25 BTC per block. The cost of electricity is unlikely to be recovered, but the computers themselves will ruin.

Suggest to start with the theory — F. A. Q for mining

Processors mine there is no sense, do not torment a piece of iron. But on the AMD 5*** series and above are quite profitable. Pugalki about the fall issue twice do not listen to the miner by Suta important hash rate, BTC price and difficulty. Here is the rest of the calculations.
