Title: GPU mining profit vs. ebay depreciation Post by: solitude on July 16, 2013, 08:00:46 PM At what difficulty does a 7850 become not worth mining assuming free electricity?
When you consider with each passing week the value of your 7850 on ebay decreases by what? A dollar? Right now a 7850 might fetch $120 on ebay. In a year you might get $70.

Assuming 310 mhash and bitcoin at $100 Title: Re: GPU mining profit vs. ebay depreciation Post by: Xyver on July 16, 2013, 09:30:37 PM Well, I currently get 285 Mhash/sec, so your 310 is pretty close to what I get.
I'm currently making 6 mBTC a day, and it's slowly dropping. At 100$, that's 0.60$ a day. So... Technically, assuming free electricity, even if you only get 0.0000001 coins, it's still profitable, because you are getting something out of "nothing". However, I'm stopping soon, (maybe 1 or 2 more difficulty increases) because I've just passed the beak even point. It takes me $0.67 a day in power to run my rig, and I'm now less then that on the coins I'm making, so I'm going to stop. Maybe once I drop below $0.40 a day, or even $0.50. I don't understand your question about the graphics card depreciation...

I don't understand your question about the graphics card depreciation... He wants to know the sweet spot for when to sell his gfx card. Presuming you bag roughly .006 btc per day with a 10% drop in earnings every 11 days the "talking out of my ass" value says to sell it in 8 months Title: Re: GPU mining profit vs. ebay depreciation Post by: Littleshop on July 17, 2013, 12:04:37 AM At what difficulty does a 7850 become not worth mining assuming free electricity? When you consider with each passing week the value of your 7850 on ebay decreases by what? A dollar? Right now a 7850 might fetch $120 on ebay. In a year you might get $70. Right now there is a big glut of miners selling on ebay and this is driving price unusually low. This will end and prices on some cards (mostly 5xxx series) may actually go up a little. If the price of BTC rises to $150+ or litecoin rises independently you will see used video cards rise in value. Title: Re: GPU mining profit vs. ebay depreciation Post by: -ck on July 17, 2013, 04:34:57 AM I would think the 2nd hand profitability goes down in large drops each time a new series of card comes out rather than progressively, so keep your 7xxx cards till just before the 8xxx cards come out.

Sure you cam ! :-)Buy a computer! :-P Title: Re: GPU mining profit vs. ebay depreciation Post by: Bonam on July 18, 2013, 04:08:00 AM If you assume an ebay price drop of $50/year, that's $0.14/day in lost sales cost. At a BTC price of $100, you need to be making 1.4 mBTC per day to break even. Right now, 300 MH/s = 5.7 mBTC/day. So you're still better off mining now and selling later, given your assumption of free electricity.
Title: Re: GPU mining profit vs. ebay depreciation Post by: HellDiverUK on July 18, 2013, 11:51:03 AM I mined the s**t out of a 5870 I got used off eBay. I got it for £80, mined it to death, sold it 5 months later for £80. It wouldn't mine any more, but played games etc OK.
I have a 6970 that I got used for £120. I mined the s**t out of it for nearly a year, and I'm now using it in my gaming rig. I expect to get another 6 months out of it, and if I get £60 for it I'll be happy. I got a pair of 7950 for £200 each, and they're still mining away like mad. Some of the same used cards on eBay are selling at more than what I paid (Gigabyte Windforce X3). I could technically turn a profit on them, if I sold today and I was lucky. Title: Re: GPU mining profit vs. ebay depreciation Post by: zvs on July 18, 2013, 01:45:15 PM ah, like buying those 5830's off of newegg in.. april of 2011 i think... with the shogun coupon? selling shogun coupon for $10, so got card for $95
then 2 years later, sells used on ebay for $120 Title: Re: GPU mining profit vs. ebay depreciation Post by: kendog77 on July 18, 2013, 07:58:04 PM 7950s are falling in value fairly quickly. I sold multiple 7950s on ebay a 4-6 weeks ago for between $250-$280, and now it looks like they are selling for around $200.

Because of increased competition from the big N I expect they'll hit $200 new soon.

I don't understand your question about the graphics card depreciation... What I dont understand, is that people get such low hash-rates woth their 7850's? I get 400mh/s with 1165 core, and low as possible mem (1500 mem LTC mining, 6000 effective) + a UNDERVOLT... Is it your coolers? I have a DCII, fans at 40% is 55 degrees = almost no noise... I let em mine whenever I can, and I did not buy them for BTC mining but gaming, so making profit is not a must for me. So, I pull ~800mh/s with 2 cards @ 300 Watts, that is about 1.43$ a day, or 43.42$ a month, I dont have to pay for power. And I have a Block erupter mining 24/7 = 17.91$ a month... Title: Re: GPU mining profit vs. ebay depreciation Post by: MrBilling on July 20, 2013, 09:44:50 PM What I don't understand is why people still mine BTCs with GPUs?
Mining LTCs is almost twice as profitable. I have had all my rigs mining LTCs for a while now. If you don't want anything to do with LTCs you could always just trade them in for BTCs. And you would get almost twice the amount of BTCs. I have 13 7950s between three rigs right now. I'm still way way way way profitable. Title: Re: GPU mining profit vs. ebay depreciation Post by: kuusj98 on July 21, 2013, 03:51:43 PM What I don't understand is why people still mine BTCs with GPUs?

And you would get almost twice the amount of BTCs. I have 13 7950s between three rigs right now. I'm still way way way way profitable. I used to mine LTC back in the days I could fetch more than .x ltc per day, it was more like 10 LTC a day... I'm minimg BTC with my Block Erupter, and LTC with my dual hd7850's....

I wouldn't expect that to happen again! Title: Re: GPU mining profit vs. ebay depreciation Post by: zvs on July 28, 2013, 02:17:52 PM I can get Radeon 7950s new locally for under $250 at the moment.

Im running at 340 Mhps im only making 0.0025 BTC today at current speed. last week I was making 0.044 BTC Its a big difference.
