for those of you that dunno what bitcoins are... wiki it.
http://en.wikipedia.org/wiki/Bitcoin

for those of you that do... do you guys mine it?

i started to mine it today (proportionally) and i use two gtx 260's... kinda slow.

I mine it at about 2bitcoins per month. (roughly 30USD)

i switched to pay per share, and im waiting to see if i get more out of that.

anyways, my vid cards are running at full speed and radiating mega heat lol.

i know guys that are mining almost 1 bitcoin per day!!! that's just over 500USD per month (at current rate), fuckin crazy.

here's the conversion/market rate for it
http://bitcoincharts.com/markets/

as of right now it's just under 17USD per bitcoin. it seems like it might be worth it to upgrade my cards to something that can mine about 1btc per day, get back the money in 2.5-3.5 months tops.

of course electricity bill might be a problem. Ive read reports of cops showing up at peoples doors with warrants cuz they think they're growing pot, but they're really just running a buncha mining computers.

anyways tell me what you guys think, or if there are any miners on rs, what's your setup? what's your advice?

What kind of setup do you need to get 1 coin a day? Some kind of triple SLI setup?

You'd need to be running something like crossfire'd 6690s

or triple crossfire 5870s and even then you will still need more to get 1 coin.

Also difficulty level will be going up, not sure at what rate, but as time goes by you'd need more firepower to make 1 coin per day.

Bitcoin has just had it’s first major theft of the cyber-currency: $500,000 worth.

Rumors of the heist have been swirling since Monday, when a Bitcoin user named Allinvain claimed 25,000 Bitcoins, technically valued at close to $500,000, had mysteriously been transferred to an unknown user’s account. Allinvain speculated the thieves made off with the windfall after using malware to compromise his Windows-based computer.

But, of course, here’s the great problem with an entirely anonymous currency. It can’t be tracked. So no one knows who has got it and no one can know who has it.

For a good background description of the whole system try this earlier Forbes story.

Think now though of the problem facing the person who says his money was stolen and of anyone who might try to trace it. It’s all, umm, anonymous. There isn’t any way of tracing it.

Think back a bit, to the days when cash could be used in large quantities with no one worrying. Unlike a credit or debit card, cheque, anything like that, cash was anonymous. If you lost it or had it stolen, that was pretty much that. You couldn’t identify, from the cash itself, who had it nor who had taken it.

And Bitcoin is set up to work this way. So there is no way to work out who has the money when they try to spend it.

Actually, it’s worse than that. There’s no way of knowing whether the guy actually had the Bitcoins he says were stolen. They were simply digits on his hard drive and now they’re not there, well, they’re not there.

I would imagine that there will be some rethinking about the cleverness of the whole Bitcoin scheme soon enough. If you have cash you might at least keep it under your bed, in a safe, perhaps in a bank. But Bitcoins must, by definition, be kept on digital media. The most likely digital media being the hard drive of a computer and that computer’s going to be connected to the internet, isn’t it?

Yes, quite, like leaving your cash on the kitchen table and then the back and front doors open given the number of trojans, viruses and malware we’re all bombarded with all the time.

But I will admit to being amused. Not only can’t we solve the crime it cannot, even in theory, be proven that a crime or theft occured.

These guys in mission were bitcoin mining and the police thought the huge spike in power consumption was a grow op.

Eventho they were not doing anything illegal the owners were stuck with the $3,500 bill for the raid.

^ That all depends how good your gpu(s) are. That will determine how fast you can mine for bitcoins. Figure out how much power your computer will use if its on 24hrs and see what your hash rate is. Then work out if its worth it. Ie, a single 5850 could net you around 300 Mh/s. And at the current difficulty rate of 1379223.42967, it will take 5 days of 24hr mining to make 1 bit coin. That one bitcoin is currently worth $17 or so. To achieve 1 bitcoin per day you would need a hash rate of at least 1500 Mh/s.

So "mining" for "bit coins" is basically distributed computing? If you are mining 24 hours a day at say 500W, you are spending at least $140 a month on power....

^ So if you are running a single stock 5870 on 500W, you will just be breaking even per month.

Or if you're running a slower video card that still uses a lot of power, you are losing money. Potentially a lot.

I bet one of these would generate a lot though :)

We only pay roughly 7 cents per kWh here (at least that's what my last bill said).

A PC pulling 500watts for 24 hours a day only works out to about $26 a month.

0.5kW x 24hours x 31days x 0.07c/kWh = $26.04

So by Tos'd's estimate of $17 every five days, you could post a profit of roughly $75 a month. That's better than a sharp stick in the eye.

The IT guys in my company have been supplying GTX460's and HD5770's in all the new PC's at work, I kind of want to install this on everyone's computer. It's not like anyone would notice a performance decrease since most people just use word and excel.

Yup, we are fortunate to have electricity at such a low cost.

Hmm I used their stupid "power saving" calculator, since I couldn't find the rate (finally found it on a pdf buried deep within their site (https://www.bchydro.com/etc/medialib/internet/documents/appcontent/your_account/BC_Hydro_Electric_Tariff.Par.0001.File.policies145 9.pdf)). Naturally, they grossly over-rate how much you can "save" by lowering power consumption. It should be more like "how much surplus can we sell at a higher rate if you use less power by buying shitty expensive ugly CFLs and low performance appliances?"

I wouldn't suggest installing it without prior consent, that could lead to some major issues (and has in the past, with it leading to jail time IIRC)

Great68
06-29-2011, 09:51 AM
Yeah I wouldn't actually do it without their OK. Realistically though, this is kind of just like SETI/folding@home that actually makes money for using your PC's resources.

06-29-2011, 09:57 AM
BTW to compare, I pay about $0.12 CAD per kWh in HK... so it would be even more for me (the price steps up very fast - first 400 units then 600. And this is for TWO months!

Yes but there would be no costs to RS and you would have 7-800 computers working at once.

Hey guess what, my friend did an article on bitcoin mining (http://www.pcper.com/reviews/Graphics-Cards/Bitcoin-Currency-and-GPU-Mining-Performance-Comparison), comparing many different video cards on how they perform. He even put together a 1000W+ monster rig that generates $3600 per year!

Here's the chart that shows the total net profit over a year (so the cost of the video card itself is subtracted, but not the cost of power consumption)

http://www.pcper.com/files/imagecache/article_max_width/review/2011-07-13/1yearprofit-beast2.jpg

As you can see, it's not worth using an Nvidia card...

And here's the power cost per year (BC would be in group D)

http://www.pcper.com/files/imagecache/article_max_width/review/2011-07-13/costperyear_0.jpg

So for Ulic who is running two GTX 260's, he is probably spending about $400 a year to make his $360 worth of bitcoins.

Handy chart! :thumbsup:

Here's the chart of dollars per day, followed by power cost per day, so you can do a direct comparison on your card:

Technically you could buy a $700 HD 6990 (or since they basically don't exist, a pair of 6970's would be roughly the same price), it would pay for itself in 132 days.

Challenge accepted?

Too bad you can't just estimate yearly earnings like that. Difficulty keeps on increasing, which means you need more processing power in the future to generate what you can right now.

At the moment you need approx. 1725 MH/s in order to earn 1 BTC a day. Which, at the current market rate is $13.71, less than what it was when this thread first started ($14+).Hey guess what, my friend did an article on bitcoin mining (http://www.pcper.com/reviews/Graphics-Cards/Bitcoin-Currency-and-GPU-Mining-Performance-Comparison), comparing many different video cards on how they perform.

Another thing to consider is that they are going to artificially increase the amount of work it takes to generate coins, as more people join the pool. So a video card that can make $3 a day today may only be generating $0.50 by the end of the year. So it will take a lot longer to pay off a video card ;)
