If its a mining machine, wipe the OS, slap on Xubuntu 12.04.3 and reinstall AMD driver and Cgminer. Often times better than trying to troubleshoot. I use Cgminer 3.3.4 on most of my machines. It seems to work fine.

How is the pool working? I switched away from it till the connection problems get ironed out (I missed about three hours of mining yesterday due to connection problems).

Dogecoin is in the tank. The coinwarz page incorrectly lists the buy price. The coin selector is working properly I believe. Now the work assignment and the pool mechanics...that is another story.

You didn't really use a Runescape screen shot in the header did you?

That looks a lot like a runite pickaxe sitting next to the "c" in cows.

Until real currency doesn't exist or is hyperinflated out of existence, in which case, you'll be holding BTC and only converting to fiat when you have to.

I think this issue is your mindset. You want bitcoin to act like what you are familiar with because the current state of bitcoin is unexplored. The people that will invest in bitcoin are the ones that are comfortable with it. You obviously are not that person.

Forbes just had an article that there are something like 250,000 people using bitcoin. That is miniscule! If 10 million or 100 million people use it, then it won't fluctuate as much. Why? Because people will be more likely to bid on a price change (buy or sell) when there are more people watching the price. Just like if you have more contracts on an infrastructure project.

I'm perfectly fine with bitcoin fluctuating, because I'm patient and I know that the internet which created this phenomenon will iron out its problems. Do I know what that solutions will be? Nope. But I know that people have innovative ideas that none of us have thought of yet.

Just resorting to the same old market strategies that have shown themselves to fail 100 times over, is not what I want to see.

With each great innovation comes change, a new way of doing things. We don't use telephone booths, because we don't need them. We don't use horses, because we have automobiles. We don't have scriveners, because we have computers and hard drives. I could go on.

There was a time when people said "How will you get anywhere without a horse?" or "Cars breakdown all the time?" or "How can you be near to an object that is 2000 degree?". And yet, the automobile has solved all those problems (through infrastructure, and technological improvements).  (Look up Voltare saying it was impossible for humans to go 50 MPH).

My point is this, you are coming up with old solutions to new problems. They will be solved, and maybe some of the solutions will be used, but on the whole, it is going fresh thinking for the bitcoin to work. Maybe these aren't even problems...they'll just solve themselves.

I've ranted long enough.

If you know what you are doing "Go forth and make money!".

Like the above poster said, there are probably reasons this hasn't been done (or some exchanges may be in the pipeline and are just taking time). But if you have the expertise, or can put together a group that can get this done you should do it.

I only encourage you because you saw what the putting up Chinese exchanges did for bitcoin...why not add another 1.1 billion potential users?

From a man's perspective I'm not surprised (not sure your gender, but I'm kind of leaning toward female only because you used grown men).

To your post, isn't that how Casinos thrive? Where I live there are five ways out of this city. In four directions there are four casinos. Most weekends they are packed. Mega Millions anyone? 99.99999999% (enough 9's) of turning a loss. Sports betting? Very common.

In our society (this world) with so much affluence in the first world, is it really all that surprising. People have money to burn and their bored. Its a bad combination.

And he is saying, why not buy 4 2/3 bitcoins at current price and make 20000 * 14/3?

You are right it doesn't make sense. Originally (and still with some scrypt and cpu coins) you could use off the shelf hardware that you might already have or could use anyway to do the mining. In some sense it was a way of using equipment, the general public arleady had, to secure a currency, the general public would use.

At this point; its just speculation, but even then it doesn't make sense. The idea with off shelf equipment is you can sell it back when you are done. A graphics card a year from now, is still a graphics card that you can sell and recoup some your initial costs. A bitcoin miner? Nope.

You might as well just buy the bitcoins, because the miner will be worth the same as the currency if it all goes down in a blaze of glory.

PS No, you are right see my post.

(with reference to next post)

There are coins you can make a profit from.

http://www.coinwarz.com/cryptocurrency

Say you pick worldcoin. Then with a AMD Radeon HD 7950 at 650 KH/s you'd be making $12.62 a day. The electricity costs at $.1 KW/h are $1.06 cents a day (assuming a pull 440 watts). Meaning you are still making $11.56 a day.

That is profit.

Its called speculation (or gambling). It is an addiction. We have banks, and markets set up to legalized gambling, with no underlying value. Welcome to the human race.

See the tulip bubble, housing bubble, etc...the asset can never go down! Until it does...

I disagree with this. Of course if you mine something established then you are likely to be priced out by the competition. People pay for the security of mining an established coin. So yes if you mean litecoin, worldcoin, or feathercoin cpu mining or mining with a low level radeon is worthless, but there are dozens of coins, some with 1 or 2 difficulty, that you can reasonably get a decent number of coins for. If that coin takes off, you can make some money. If you were mining dogecoin, two weeks ago at 1 difficulty, you'd probably have made a few grand, even with a cpu.

Does anyone know if there exists a chart with the fees for each exchange listed? It would be most helpful for deciding where to exchange coins.

Technically the intel GPU is on the chip CPU right? You could CPU mine dogecoin, but the returns would be significantly less. I'm not sure there is a setup to specifically use the intel on board GPU for mining. At least, in my travels, I've never seen it.

With the above comment on an external fan I bought a boxfan for $18 from Walmart.

The side of the case has holes in it, so I put the boxfan on the side of the case and blow air in. The key is to have the airflow from the top, down on the GPUs.

At least for my setup, this avoids the heat trap. I tried blowing air from the front, but it did not do much. By having the air blowing in from the top of the graphics cards, it basically blows the air away from the point source, that would be the cards themselves. I saw about a 4 degree C reduction on the hot card (I have two) and a 7 to 8 degree reduction on the cooler card. The box fan pulls 70 watts from the wall (I have it on low, which maybe 40 I can't remember).

Probably the easiest quickest way to save some life on your cards.

You can check Cgminer to see if you are having any success. Keep moving the fan till you get the best cooling solution. Also, higher flow of air, does not mean cooler gpu.

The key question for the PSU is your 12V rail. If you can cover the TDP of the GPU and the CPU as well as wattage for memory, optical drives, and the northbridge, you'll be okay. Not all of those work off of 12V. Personally I just strip out the optical drive. The hard drive and memory take 5 to 10 watts each and the northbridge takes 20ish. So if you want a theoretical max take TDP of GPU + CPU + 40 watts (and don't have a DVD in the optical drive...).

On your PSU you can check what the 12V rail is rated. So for a 430 watt CX psu for example, the 12V rail is rated at 384 watts (32 AMPS * 12 VOLTS = 384 WATTS). You need the total internal pull on your system to be less than 384. Now really, as a bare minimum, if you want your PSU to last any sort of time, you need to be at least 10 percent under that target so (384-38=346) to cover power fluctuations and not overwork the PSU, but if you want to be safe (and you should PSUs cost money) try to be 20 percent under (384-77=307). So your total system in this case should be pulling 307 watts maximum.

Another note (although I haven't tried it myself) is that I have heard that LTC/scrypt mining needs one open core. So if you have multiple cores, try to only use N-1 (where N is the number of cores in the CPU) for the CPU coin. That way you wont weaken your LTC or scrypt return.

Happy mining.

Depends on your setup. If you are mining with cpu, maybe primecoin or protoshares. If you are mining with gpus then worldcoin. That would be the top profit making as well as most well established coin.

Dogecoin has been around for what, two weeks? Can we tell much about a coin from two weeks of existence?

LTC, highly mined at the moment, well established, but your returns will be lower.

Other coins, quite a few risks, hard to pick out the ones with good communities from those that are around this week and gone tomorrow.

My vote is for worldcoin or primecoin.
