Guys, i'm italian.
here, to build a gpu mining rig, whit 5 r9 280x for a 3.6 Mh/s, you pay about 2000 euro.
estimated consumption even undervolting cards, is about 1.4 Kw/h that costs about 5.00 euro/day
the Gridseed ASIC, if i right understand, have 5 chips even "usb device" and it can do about 300 Khash/s for a consumption of about 30V. so, 10 device that i read cost 1360$ (1000 euro) would get 3,0 Mhash/s for about 300V. power costs is about 1.10 euro/day
ASIC miner 1euro = 3 Khash/s + 1.10 euro power/day
GPU miner 1 euro =1.8 Khash/s + 5.00 euro power/day
assuming that 1Mh made 0.01 BTC day:
asic miner made 0.03 BTC/day that is 25.5$ (18.75 euro) - power (1.10 euro) total 17.65 euro/day net (time to autopay 57 days)
GPU miner made 0.036 BTC/day that is 30.6$ (22.50 euro) - power (5.00 euro) total 17.50 euro/day net (time to autopay 114 days)
not counting space problems, overheating, noise etc.
in Italy, Gridseed ASIC is much more profittable than any GPU for scrypt mining now.

This is the (unfortunate) misconception that came about with poor translation and horrible press from Gridseed. The cost for a single USB machine (which includes 6x 60kh/s units) is $82 + 6 x $65 = $472. So you're paying $472 for 360kh/s. The minimum order is 10 of *these*, not 10 single chips (unless I'm mistaken), making the total for 3.6MH/s of hashing power $4720.
Indeed, and it's 5 chips on each miner operating at between 300-360 total (not each).
As for power, it appears to be .44W per chip in LTC mode and 5.3W per chip in hybrid mode
Here is where the chip prices were first confirmed at about $65:

Development board: each 500 yuan
chip: 400 yuan per piece, per pack of 1600 yuan four chips
This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person.

And here is a link to the specs sheet of the chips

I'm interested to see what happens with these.
Re: [ANN] profit switching auto-exchanging pool - middlecoin.com
H2O claims this pool is his full time job + 2 employees he has...but he rarely ever posts.
Now this guy with 500 MHash is leaving the pool because it is making less than straight mining Litecoin. He knows whats up!

It does seem possible...any relatively easy for him to get away with. Still I'll have to test it for myself...
Re: [ANN] profit switching auto-exchanging pool - middlecoin.com
Can someone explain why we're mining litecoins instead of other more profitable alt-coins?
LTC would show in cgminer with a diff of 3.37K or 221M, depending which version you have. I don't see that diff now, we seem to be switching between DOGE and CAT (17.3M and 6.45M).
Seems to be bouncing back between Chinacoin (3.08M), CAT, and LTC now...all the alts are doing shit right now by the looks of it

pool is to big to mine alt coins and sell without crashing them to zero.
Re: [ANN] profit switching auto-exchanging pool - middlecoin.com
The pool may be getting too big for its own good. H2O really needs to split and point to different coins soon.
Without reading all 100+ page, any chance you could tell me in short why the pool becoming bigger is a bad thing?
More miners means more hashrate meaning:
-more coin swapping as difficulty adjustments hit harder
-hurts dedicated miners of the coin when we leave them with high difficulty
-more miners here likely means more everywhere, meaning lower profits across the board
If we split the miners across two or more coins this could mean greater stability in the difficulty of individual coins, and possibly better long term profits. We would have to have some kind of method of determining who gets to mine the best coins, and who mines the subpar coins though. Maybe round-robin style of approach, or maybe just based on raw hashrate (aka you earn h20 more fees so you get the best work to hash)
If he left people off the best coins then people would leave this pool in droves and go to the pools that don't intentionally screw part of the pool, or just mine the best coin themselves. Why would anyone think this is an ok idea? If a coin is the best value its the best value, just milk it. I don't think cutting the hash in half would make that much improvement, it would just lower profits all around.
Well really it could already be happening. We have no idea what we're mining at anytime. I agree that it's hard to say if cutting the hash would actually help or not; but focusing a hashpower laser on any one coin doesn't seem to be the best idea either. We might run into issues where we mine so much that the market can't even sustain our trade at the prices that we were originally mining at.

Re: [ANN] profit switching auto-exchanging pool - middlecoin.com
Hashrate seems to have increased from 2.5GH to 3.6GH in less than 48 hours. Thats amazing.
going to mean lower profits
Though we've done excellently these past few days.
Re: [ANN][Pool][Profit-Switch][Optional Auto-Exchange per Coin][Vardiff] ~ Hashcows
Good to see that the cows are working on the issue...I've unfortunately have had to redirect my primary pool to middle coin for the time being. Though I have every intention of coming back to you guys once the connectivity issues are resolved

Re: [ANN][Pool][Profit-Switch][Optional Auto-Exchange per Coin][Vardiff] ~ Hashcows
I'm still really confused about the estimated daily earnings...I check it earlier and it said .023, but then I got a payout for .067?
Estimated payouts seem incredibly inaccurate compared to the final payout. I'd much rather see a this is how many of each coin you personally have mined type thing, so you can self estimate it against say cryptsy prices to figure out how much you will likely have once the pool sells the coins for you.

Re: [ANN][Pool][Profit-Switch][Optional Auto-Exchange per Coin][Vardiff] ~ Hashcows
So a few things.
-I really like the idea of hashcows and it seems super convinient, but I'm having trouble understanding the estimated daily payouts. Is this number the estimated ammount of BTC that I can EARN if I keep mining at a static rate with a static price? Or is the number if coins that I have ALREADY earned and its just displaying the estimated 'if we sold all you've earned so far now and you stopped mining then this is your total payout'?
-I noticed that after running for about 24 hours with variable 3.50-5.0MH/s (two of our cards are in personal gaming rigs :p) I only netted a bit over 0.05 BTC. Now I'm not sure if this is because of maybe backlogged coins that you haven't sold or what...but I shouldn't I in theory be earning twice if not three times that number?
-Create more of a community, like a local forum where hashcows users can talk and share stuff. Or even just a chatbox on the mainpage itself. Can go a long way to building your pool if done well.

The 7990 gets such great hashrate because of what it is. Not one, but two GPUs running on the same card. Meaning twice the heat coming off of them, as well as additional fan noise, and the possibility for one core being less stable than the other.
Are you dropping the voltage at all? This can make a huge impact on heat (undervolting can make it much cooler).

Because they sell them for more btc that they can ever mine. You should ask why people are buying them instead...
It's the alure of get rich quick. ASICs are a a shiny new toy that promises to magically pour out money, but they halve in efficiency so often that they barely break even...
There was a lot of fuss regarding Quarkcoin in the last few days. Now, it's dropping. What do you think? Is that it for QRK? Or will it continue to grow?
Premined scamcoin. Cool idea, bad backing
