Wonder what difficulty we will eventually stabilize at? And sometime in the future payout will decrease to 25BTC per block too. You gotta think that it will just push up the value.

I agree. If the price of the coin goes up... Its an even balance but, who knows.

Difficulty growth cannot continue indefinitely, because the network cannot be infinitely large.

I'm doing 3200 mega hash and my rigs cost me $250 a month on electricity.

It's amazing that the mining hardware just keeps piling in --



Yes, but than again it is still profitable. I thought mining would be over by now, but it just does not want to give up.

My 8 miners acquired 3.5 BTC in the last 22 hours. Even at $10 per BTC, that is $35. My electricity max per box (4 PCs), is roughly $1 for the day, therefore $4 in total.

I reckon that a lot of the new miners are just people using equipment that they already had, maybe with a gfx card upgrade or two. They've watched and listened while someone they know has had their computers making money for them, and finally they have decided to give it a go. "Hell, even if it's just a few dollars, a few dollars a day pays for fuel Smiley ", they may reason.



I seem to have about the same mining income as you -- only I have 12 cards.  All pretty efficient ones, too (5800 series). I run a pretty lean ship here.  But my electricity cost is around 74 kW/h per day. I keep close tabs on my electricity usage. I regularly write down what the meter on the side of my house reads, so I'm familiar with my normal daily kW/h usage.  I also own a Kill-a-Watt meter.

I'm including the cost of extra air conditioning. I live in Texas, where we haven't had a cloudy day in weeks, and the temp hits 105 some days.

I think some guys are reporting less cost, because they don't (or can't) count the cost of fans, A/C, etc.

Anyhow, 74 kW/h comes out to $6.51. And that's a 8.8c per kW/h, which is certainly average if not cheaper than most. And that figure is super-accurate as well. I took my electric bill, subtracted the Statement Fee ($15.00), and divided what was left by the number of kW/h I used -- which equaled 8.8 cents.

You're saying $1 each for 4 machines, which have enough graphics cards to produce 3.5 BTC/day? That's 3.3 GH/s.

I think everyone needs to go back to the drawing board and double check how much they're REALLY spending on mining. You might be surprised.

Im also mining in texas... and I have 0 AC costs. Running my cards in the garage yields ~5c higher temps than running them inside, only added cost is my 4 box fans @ 75w each. My 4 rigs @8.5c/KwH are using ~5.25 in cost per day, while putting out ~2.5g/hash. Each rig is pulling down around 500-750W, Unclocking the memory to ~340 helped cut the machine usage by almost 100W per box.

Yea totally not cool.  I'm shocked that the network is growing at this rate considering the drop in coin prices + mt gox has been down.......  INSANE!

Still delayed reaction to the surge up to 30$/BTC imo, we might see a decline in growth reflecting current events in about 2 weeks time.

Profitable compared to electricity, but... how much did those 8 miners cost you to set up? What is your ROI for the next 6 difficulty increases if they're all 50%, and all happen in 9-12 days?

My stats are that I'm earning $17 a day (taking into account currency conversions and MtGox fees) but power costs $5 per day (measured, not just estimated from parts specs).  Not everyone pays a few cents per kilowatt like US/Canadian citizens seem to do.  With a 50% difficulty increase that'll be $12 per day but still burning $5 in power.  Does it make sense to have $1000 of hardware producing less than $5 a day?  (Don't forget taxes must be paid on income).  Bitcoin's USD$ value did not increase at all in the last two difficulty increases, and there is no evidence this trend is about to change.  MtGox's little adventure is unlikely to have a stimulating effect on speculators either.

I have a feeling many bitcoin users are piling in without giving regard to the cost of power (and the cost of cooling where required).  Pretty soon they'll be thinking "free cash!" while spending $1.10 to make $1.

That's how I got into it. I'm mining on a PC that I built in February because my old one was about 3 years old and getting dated. The hardware was just sitting there running 24/7 anyways when I stumbled into bitcoins and I decided it was worth it to give it a go. So far my mining proceds have paid for an added video card so even if I stop now I'm still ahead.

Are you ready? Just wondering what would be the difficulty jump after that...

How do you find this out?

I found this page, but it shows just a 43.3% increase
