Cryptocoin Mining?

I currently use Invasion Network. Extremely low stale rate, consistent hashing, no down time since I started. Though with LTC profitability nearly matching BTC, I might be switching back, because I can get higher rates with BTC over LTC.
 
Both invasion and the ozcoin LTC pool are good for LTC, but with the LTC prices as they are, it's silly to mine LTC. I think it needs to be at least 20% higher profit than BTC for me to hassle with the additional heat, additional configuration PITA, and the additional fees incurred to convert to $$.

Although...worldcoin is currently showing as 400%+ profit compared to bitcoin....hmmm.
 
Running his numbers with my power cost LTC is more profitable for me still, not by much though like 30 cents more a day.

LTC price really stagnated/tanked, it needs to hit $6 to be as profitable as it was just a few weeks ago.

It was nice when LTC diff was 80. I racked up 100 coins on a 6870 in a week or so. Then the price spiked and now its slow going.
 
About to snag a new video card, most likely a 7950 and have been wondering what rate people are mining at in terms of bitcoin or other cryptocurrencies. I know BFL and Avalon pretty much ruined bitcoin mining but BFL's units are hitting the market at a really unsteady pace so anyone still mining with cards and getting decent rates? Not getting the card for mining but mainly for gaming, if I could mine with it for a month or two before BFL units really hit the market I wouldn't mind since I have other toys and projects in the works wouldn't mind covering part of the cost of the card.
 
I have shut down My Miners.........
I don't have my A/C on so they are taking time off.
Room Temps were getting 35°c and VRM were touching 90°c......
I will wait till A/C get turn on.....

It's still profitable at the moment. At current prices you'd be making a little under $3 a day if you manage 600mhash and pay $0.10 per kwh. 600 is about what I get with my 7950 at 1125MHz.

Not bad, about 3 months at current difficulties with a bit of scaling up would pay for the card more or less. The 7790s are the sweet spot for mining performance relative to power consumption and cost though right? Anyone here still running dedicated mining rigs? If the cards can pay themselves off in under 4 months I'd consider grabbing 2 or 3 since I'll have other budget machines to put them into later for better graphics performance.

If you plan on using the cards again for anything then I suggest the 7950, since then you will have really long lasting (in usefulness) cards.

7790 will have basically zero resale value as well as usefulness very quickly.

For example, Nvidia Geforce 570 GTX still goes for 177 USD on ebay

Definitely thinking the 7950 for myself. But I'm gonna need to do a refresh of most of the computers in my house for my family, and none of them do anything particularly graphically intensive. Most of them actually operate on integrated GPUs albeit they're slow for tasks beyond basic video. So the thought was, buy a few 7790s, mine till they've paid themselves off and maybe a bit more depending on the rate of return on them, then retire them from mining and use them as dedicated GPUs for family systems.

Yeah I am running 9 rigs. cut back from 13 . 11000 hash is now 7000

I have a lot of hd7790's 8 of them. the rest are 7970's. maybe 8 of them so 16 gpus in all had 22 or 23

I sold a few 7970's one 7990 a couple of 7950's.

New Jersey has had a cold spring so ac bill is not bad so far.
But I will not be able to run when it is 85f outside my house. Still making money. Now about 30 bucks a day. After power.

I do not post any gear for sale here on Anandtech, but I will have a lot of gear to sell in about 1 month. My asics from bfl are never going to come but I am a few thousand ahead once I sell all the gear in early july even at half price I should clear 3 or 4 grand back which will be all profit.

free.

though after running the numbers, with a 10% increase in difficulty every 14 days. a 7950 will never pay for it self.

The problem is there is no way to know for sure. Yes you can probably count on a 10% difficulty increase every couple weeks, but what sort of BTC value can you count on? Maybe it drops to $20 a coin, maybe it rises to $200.

Buying dedicated mining hardware is a gamble no matter how you look at it. I took it on last month, am happy to say that I'm at the point now of mining coins with no risk (except the monthly power bill). If BTC value dropped significantly I could sell my hardware and come out on top.

It hasn't paid for itself yet, but at least I took the gamble out
 
The hd7790's I purchased on April 1 were almost 100% paid for from prior mining profits.

First off I sold my hd7990 that cost me 963 with tax on the first of dec for 800. I also sold the games for 50 back in dec and got 30 in rebates so 963- 800 = 163- 50 = 113 -30 = 83 the card mined a lot of coins from dec 1 to apr. at least 1100.00 after power so 1100 -83 = 1017 ahead on this card .

I spent it on the hd7790's about 1200 for 8 so my hd7790's cost about 183. really more like 0 with rebates selling codes.


the 8 cards have hashed at 2400 for about 50 days pulling 640 watts. using todays diff of 11 mill today price of 123 my power of 16 cents a k-watt they have about 500 - 525 profit. Still making about 10 bucks a day for the 8 of them. That 525 does not count resale . It does not account for the big price spike of 230 plus. I sold 3 or 4 coins over 200 in apr.

If you have a running system the price is low for a hd7790 under 140 even under 120 on a good sale.

BTC has been a fun ride for me. Made money and got to play with a lot of toys.

Well done. That's how it should be :thumbsup:

I am too lazy to bother with it myself :whiste:

you are correct, if BTC value jumps to 200. Then its profitable.

But when you are estimating risk vs reward. you have to use what you know.

IE currently bitcoin has been reasonable stable at 110-120. difficulty has been going up ~15% (i used 10% in my calculation) each period.

given my electrical costs of $.138/kw. my earnings would top out at ~130 dollars after 154days. after which it would cost more to run the 7950 then it produced.
 
Hey guys. Im building a dedicated mining rig since I dont have to worry about electricity cost at my current location.

I have a spare 7950 and a seasonic modular 650 watt psu so that is my starting point. Which cpu and motheboard should I get? I dont have a cpu brand preference but I'll take whatever is cheaper in this case.

Is it worth going with three 7950's if electricity is not a concern? I would at the minimum want two cards and am aiming for 1000 hash, thanks!

may I suggest 2x hd7790's they will pull a max of 160 watts and hash at 600 1 wire each

the 7950 can do 500 easy. so you pull 1100 hash the psu you have can do it easy.
