3021  Bitcoin / Bitcoin Discussion / Re: A case AGAINST merging Namecoin and Bitcoin mining on: July 20, 2011, 12:52:07 AM
I think merging them is a mistake.  Keeping them separate will allow for more flexibility with both.   Namecoin's block chain will become secure enough as it gets used for more and more important things. 

One of the FEW drawbacks of BitCoin is the size of the block chain.  It already interferes (though I know there are workarounds) with mobile applications.   Why would you want to make it bigger? 

Merging the two block chains does not add as much value as it takes away from both projects.

3022  Economy / Goods / Re: SELLING 2x 6990 mining rig $200 off FROM LAST TIME on: July 19, 2011, 02:58:20 AM
As a bitcoin mining rig it is a bad deal but the parts are worth some real money. It is a bad deal because the 6990 is not a cheap card for mining but they are IN DEMAND for gaming.   The cards are worth $1500, the power supply $200 and the rest at least $100.  If the  CPU, HD and ram were upgraded it could go for some real money as a gaming rig.

Start it at $1800 and it should sell.  It MAY go for $2100 but that would be from someone who just is crazy to get those 6990's.

Well, I thought there would be a little more interest in my business.  I am assuming that no one with that amount of bitcoins or cash has viewed this yet or no one wants to relocate because this is one heck of a deal!

It has only been a few days since you posted.  This forum is probably not the ideal place to list something like a business for sale, but you should give it time before you conclude there is no interest.

3028  Bitcoin / Mining / Re: What is your mining speed? on: July 15, 2011, 05:12:06 AM
If you buy JUST a video card and put it in an existing system it may pay off.  Buying a system you already wanted and putting it to mining can take down some of your purchase cost and make it worthwhile.  Buying a bulk load of systems can not pay off anymore.  You will loose more in depreciation then you will make back in the first few months.  Over the longer term the payout will be lower and lower and will not ever cover the full price of the hardware+electricity.

Careful there.  Sounds an awful lot like you're predicting difficulty and the price of the BTC.

You are correct.....  but you can run the business analysis on the most possible outcomes to see what is a good move and what isnt. 

If the price of bitcoins go up and difficulty goes up, buying the coins would be the best move.


If the price stays within the range of 10-20 and difficulty continues to rise slowly then mining still does not make sense FOR NEW FULL MACHINE RIGS. 

If the price of bitcoin tanks, (no matter what difficulty does) then you loose money on either mining or purchasing.

A final scenario of price staying even or rising and difficulty lowering will not happen due to the competitive market and new miners joining.

There is no scenario with any odds of happening that puts mining better then buying FOR NEW FULL MACHINE RIGS.




3029  Bitcoin / Mining / Re: What is your mining speed? on: July 14, 2011, 10:15:07 PM
Do you know something the rest of us don't?

Just hoping Bitcoin rockets up in price, eh? 

And you must be hosting those rigs in a building outside your home -- you can't exactly draw that much power at a residence.

I mean, there are plenty of guys on here content to make "a little", mine for fun, mine to pay for a % of new hardware which will be used for gaming, etc.
But you're obviously in this as a business, to make money plain and simple.

The 130-150 day payoff doesn't hold you back at all?

Besides the fact you physically won't be able to get your money back for 4 or 5 months (with no difficulty increases), we're also not factoring in the value of one's time -- I mean, unless you're unemployed, it's going to take some of your otherwise productive time to build all those rigs.

It made sense in late May when profitability was through the roof -- it WAS worth one's time to build and mess with rigs.

But now, it only makes sense for EXISTING operations to continue, perhaps strategically expand here and there.  Mining just isn't THAT profitable anymore, and it's still plenty risky.

Has anyone noticed that BTC haven't been over $14.20 for several days? And now the price is finally moving -- to $13.80.

Like I said, risky. Risking a few hundred bucks makes sense. But starting a business -- this late in the game? A bit foolhardy if you ask me.


Well, lets jsut say it is less risky than some of the other items. I have the hugh luck to actualyl run a business Wink Result is that I now buy wholesale.

This is my "dc-0" plan that long looked for a reason to go into existence. I need some volume to make it worthwhile, including having industrial power which where I am requires me to take 63 amps and some minimum amount Wink

Plus I am not unemployed - to a degree where I can be happy to say that this whole oder if it is a total loss is a dent in my income for this year, but one that is... manageable. Time? Yes, 2 people working on that full time at the moment Wink

I dont really see that as "end of the line". The goal is to add a half rack (8 computers) every month for the foreseeable future, more and more financed by the mining income.

If it fails I am stuck with
* A lot of hardware to sell of
* A decent tax write off
* An experience that cost me maybe 2 months savings

Wink Not all that bad. The worst is a total crash in a month that measn I have no real write off but used hardware Wink And a really good experience. I may take chance to move that into an import business Wink

If I am right, I run this into the 16 full rack (16 computers each) setup next year.

Wholesale is not really that much cheaper then mail order.  In many cases, newegg=wholesale or within 5%. 

There really is no scenario where buying that much hardware NOW will pay off better then buying bitcoins.  The only way you could come out ahead is if difficulty goes down dramatically while price stays the same.  That simply will not happen.

If you buy JUST a video card and put it in an existing system it may pay off.  Buying a system you already wanted and putting it to mining can take down some of your purchase cost and make it worthwhile.  Buying a bulk load of systems can not pay off anymore.  You will loose more in depreciation then you will make back in the first few months.  Over the longer term the payout will be lower and lower and will not ever cover the full price of the hardware+electricity.

If it does not come with a printed certificate from Microsoft that you send in the mail it is not legit. 

Otherwise those keys that are just a code transferred from one person to the other tend to stop working after 1-3 months or if the seller keeps selling the same code.

All three sellers are 100% feedback.

All three customers could pay with CC and get 2% ebay bucks back and a credit card reward if they had one.

I would pay $720 in BTC for one of the used cards that had box and all parts.

3033  Bitcoin / Mining / Re: AMD Brand New APU! on: July 13, 2011, 03:15:39 AM
You are overpaying for the 60mh/s AND paying more electricity as the APU uses more power then a CPU with the same power.  And you are using 50 watts over a sempron 140 that would make the most sense in mining.
Sorry but your logic is flawed and you are simply wrong.

You're saying that using a Sempron 140 sitting around doing nothing and draining 50w is better than an APU hashing at 65-75mh/s and draining nearly the same energy?

You think the APU will drain 100w at 65mh/s?

Nope.  The 5870m in my Alienware laptop has a TDP of 50w and hashes at 152mh/s at stock clock.  The APU was designed from the Mobility series and has an even higher efficiency rating than the Mobility series.  So, like I said, the hashing power of the APU is nearly free (compared to an equivalent CPU).

There is no reason to build a rig from this point forward with a useless CPU when you could be using that slot for efficient extra hashing.
Sorry, but you are simply wrong. 

The a8 that will do 65 mh/s APU is rated at 100W and the Sempron is rated at 45w.  You are paying $90 more for the cpu, and you are drawing 55w more power.  The Sempron has only one core (at least one turned on), the A8 has four.  Even idle they waste some power. 

You say the hashing power is free.  It is not and I am not wrong.

3035  Bitcoin / Mining / Re: AMD Brand New APU! on: July 12, 2011, 03:15:24 PM
what about the

-Boost visual performance by at least 40% when you combine an AMD A-Series APU with select AMD Radeon HD 6000 Series graphics cards. if a 6990 is hashing at 800 and 40% increase would add 320 mh/s? wouldn't that be well worth the extra money?

That is marketing-speak from AMD.  Notice the word 'select' in there.  If you have a 6990 and switch to an APU cpu you will get 60 MH/s or so for mining from the APU.  It will not change depending on your main video card.
3036  Economy / Economics / Re: If dollars crash to a value of 0, what happens to USA's national debt? on: July 12, 2011, 12:28:48 PM
Interestingly right now we get a discount on our debt.  Others in effect are paying to take our debt.  The interest rate we pay them is lower then the inflation rate.  The buyer is paying for the security that we will pay them back with a small amount of interest, vs their money sitting around devaluing (through inflation) with no interest.

If the dollar crashes (not to zero but to half its current value) we get a huge discount on our existing debt but have to pay through the nose for new debt.  So if we STOPPED pulling new debt (which is quite possible) and experienced large inflation, we would get a huge discount on all of that money we borrowed.  It could happen.

He is always ready to give you a crash after your panic buying.
Keep money in hand and be patient, withdraw your open bid orders, to help the price fall, and you will get cheap coins.

 Be afraid, be very afraid.

I don't see what's wrong with being aware of the existence of the big holders, especially those ones who are always ready to slash the market. Stop yourselves from panic buying and always being patient, you will get better chance to buy in at a cheap price.


Because slashing the market is in the interest of big BTC holders?    Huh

People have different view about the future of bitcoin. Maybe the big BTC holders are not big believers.

That is even dumber then your first statement.  So there is a big BTC holder who HATES his BTC and he wants to destroy the value of them? 

3038  Bitcoin / Mining / Re: eBay update: prices coming way down on: July 12, 2011, 03:41:10 AM
Honestly, he knows what he is doing and that is trying to get people to "quit" with his faux-doom and gloom.  But you guys play into it by replying and letting his posts get more attention.  Every time we respond, it gets put to the top.  I guess at this moment in time I am guilty of it but just ignore him if you don't believe what he says and move along.

By the way, did you come up with this on your own, or are you just vomiting what others have said?

Really, I'm going to have to go ahead and call you out on this one.

What doom and gloom? Can you give quotes?  Can you prove that it was some kind of scaremongering, and not simple reporting of the facts?

I'm all ears...

*crickets chirping*

It is an overly doom and gloom thread but ebay prices are coming down.  Not WAY down as he said though. 

the 5870 on the 10th and the 11th sold for between $208 and $232 with most of them being $225

Two weeks ago it was $231 to $339 with most of them being $275. 



3039  Bitcoin / Mining / Re: AMD Brand New APU! on: July 12, 2011, 03:33:14 AM
Because if you put the $90 into a better card you in most cases would get more
That's a silly argument.

1.  The discrete card will require more equivalent power than the nearly free hashing power from the integrated GPU.
2.  The discrete card will use up a valuable pcie slot on the mobo (if you are going for full density.)
3.  On normal rigs the CPU slot is wasted by an inefficent SLA-256 calculator.  The APU remedies this.
4.  All other things being equal, a rig built with the APU will outhash the same rig built with a standard CPU.

There really is no argument.

Spending $90 more for 60MH/s is silly. 

Your point 1 is wrong.  You are not getting free hashing power.  You are overpaying for the 60mh/s AND paying more electricity as the APU uses more power then a CPU with the same power.  And you are using 50 watts over a sempron 140 that would make the most sense in mining.

$90 will buy a 5770 that will do 1/3 more hashes then the APU

going from a 5830 to a 5870 will cost about $90 and give you more then 60 MH/S
going from a 6950 to a 6970 will cost about $90 or less and give you more then 60 MH/S

I under volt my 6990 to 1.075 from stock which I think is 1.175 and it saves about 30 watts but really keeps the noise down.  I run at 830 not at 860+ that would need more then 1.250 volts.
