The Pi is better value than the Block Erupter

Then add the cost of the Raspberry Pi on top of the 2.6BTC before you work out the ROI

If your miner makes less than a dollar a day and you computer uses more than a dollar a day in electricity what then.

Smart people count the power cost of the PC to run their mining.

What are you talking about by concentrating the hash power into smaller number of hands, increases the chance of a 51% attack.

You need only one computer to run one or several Block Erupters, think about it.

Yeah, Jody said they just hired two more people in shipping.

I don't think a single unit will ever break even, multiple should. The single unit will barely make $1/day, it won't talk many doublings of difficulty to drop that revenue down so it won't cover the electricity cost of the computer it's plugged into, which all of a sudden has to stay on 24 x 7 for the miner.

The ASIC hash rate war is proving to be a drama. What I see happening is the ASIC vendors released their units with two much hash power, this will cost them sales and profits in the near future with BFL being the worst offender.

Instead of introducing the TH/s to the network spread around to thousands of miners in small chunks, they told everyone about the Minirig. People with deep pockets have ordered hundreds so when they finally ship, the TH/s will explode overnight. This will drive the smaller miners away from BTC and buying BFL product as the smaller units wont be able to compete, and the average miner wont be able to afford competitive rigs any longer, the gap is too large. So the mining will be concentrated into a smaller and smaller group of players with deep pockets. They will be able to dominate at a far cheaper cost than otherwise would have been possible for two reasons. Firstly BFL sold the Minirig too cheap, per GH/s compared to all other products on the market including their own lesser models. Secondly the instant concentration of hashing power will reduce the other miners revenue far more abruptly than if the whole net rose gradually, that will cause shock and awe not unlike a market crash.

Of course BFL are not alone, the Avalon 66GH/s unit was too big, they should have started with a 22 GH/s unit or smaller, and shipped 3 times as many of them.

Kncminer are talking about a 175GH/s an 350GH/s which are once again too much hash power.

Up until now everyone added hashing power in small increments adding a GPU or two, the crazies built racks of the things, but overall there were no big jumps. That's all about to change and I think for the worse. BTC was all about decentralization, these unnecessarily large ASIC sizes that are coming, screws up that concept.

I am also having cooling problems with the Gigabyte 7970 Ghz version.  Mostly mining scrypt coins where you need to keep the mem clock up. I discovered that if you set the GPU engine clock to exactly 1000MHz the card will lower the voltage to 1.2v down from the default 1.256v which helps the cooling a bit.

I am looking at replacing the stock cooler with Arctic Cooling Accelero Xtreme 7970 kit. but I think I will try 2 x 120mm fans instead of the standard 3 x 92mm fans first and see if that makes any difference.

Open to any suggestions, the card is proving very tricky to cool.

It's not and assumption at all, it's clearly observable in their product videos and screen shots they have released.

I would certainly hope they have done substantial live testing on all model prototypes at least. I don't want an unproven product.

With the current diff increase, these things mine about 0.01BTC per day, so it would pay for itself in only 260days assuming the difficulty doesn't go up in that time! In reality it will probably take years to generate 2.6BTC

If BFL had shipped even one minirig, BFL_Jody would be all over the blog telling the world about it, being the one that sends the orders to production!

BFL use eclipsemc.com when live testing.

It's getting there, probably be right in July.

Starts are always messy, a certain number of bocks have to be found before a diff re-target kicks in,  and the blocks come quickly initially, that's why you back off the rewards. Also you get a lot of orphans at the start until the difficulty creeps up, so it took a couple of hours solo mining before I found any blocks.  After a few hours it had pretty much sorted itself out as p2pools came on line and people mostly stopped solo mining.

The miner pumps are done, now it's the trader pumps like fontas et. al. that have taken over. So it becomes a more interesting coin to trade. Miners just send the price straight down which sucks for everyone, traders send it up and down creating opportunities.

Considering DGC has been out for several weeks now, it kind of blows your pump and dump theory, the miners already tried that back in May.

DGC has moved along since then.


Of course insta-mine claims absolute BS, if folks knew anything about DGC they would have known it has built in insta-mine protection in the source code put there by the devs.

It's actually a clone of LTC if you examine the source, with several parameter changes for the better.




The DGC block reward is far more practical at 20, WDC produces way too many coins per hour which makes it cheap.

The only thing I would like to see changed in DGC is the number of confirmations increased from 4 to 10, with a 20sec block rate this is no big deal, but it would inspire confidence in people that understand the probability of a double spend attack.

Perhaps the pools are struggling with the hash rate?

I am on bigvern's too and it seems to be working for me.

What I found works best is if I use the cgminer --load-balance options with two pools, then if something is a bit funny with one, it will put most of the effort into the other one.
