Mt. Gox needs to add security features. Pins and two-factor authentication would be a good start.

It's not the vendors... look...
We can agree on this. The supply of bitcoins is fixed. Some portion of all the coins created up until this point are for sale.
The demand for bitcoins is growing. With all of the recent news about Bitcoin, many new people have been finding out about it and wanting to buy bitcoins.
Steady supply + increasing demand = rise in prices
If as ceiling ask is place by an earlier adopter there are no "rising prices" so what you get is: Steady supply + stagnant demand = stagnant or falling prices No one is digging through that 5000 btc blocking ask any time soon. You keep dwelling on this evidence and I keep pointing you to the charts. |

Hi,
I plan getting a new video-card, but I'm new to the scene, so I could use some confirmation.
As in the title, the cards : MSI Radeon 6870, GIGABYTE HD5850 or SAPPHIRE HD5830
I would like a card which has ~300 Mhash/s (preferably without overclocking) , can make a difference between 2D and 3D use (I heard Gigabyte had problems with this), the fans that comes with it are enough to keep it cool, and keeps a low noise level while mining, because I plan to leave my computer on 24/7.
I'm leaning towards the MSI, but not sure of it.
Also, another question : in the hardware comparison, i see that the Mhash/s gets better if i downclock the memory to 300Mhz. Why is that?
Thanks!.
5830's give a great bang for the buck if you can find them at a reasonable price. Newegg just had a new shipment of the 5830's in and sold them out in about an hour today... Damn I don't think their notify system works very well. |

So say I send 10 bitcoins to some one and right at that moment they lose their internet connection. Or There computer crashes. Are the bitcoins lost forever?  And yes I am new. Started mining yesterday at 204 mh/s bought 2 more GPU but there on back order looking for a GPU that can give me 200mh/s under 190 bucks ea. if any one has any ideas. Love you thanks and long live Bitcoin!  No worries, your bitcoin client will catch up to the current block when it next connects. |

Yea. ZOMG ITS GOING TO THE MOON. OMG ITS CRASHING. OMG STAGNATION... People need to relax. Start doing business in bitcoin other than trading and the price will more and more stabilize  I don't believe I OMG'ed once.  |

I cannot see why you would do this. Everything that is not a video card is not making you money and 5830's, 5850's and 5870's are nearly impossible to find. |

Certainly appears to be one in the same. So, what's the next step??
There is no next step, he has the coins, he wins, game over. |

You dont need to lock it to anything
Exactly people need to stop trying to "fix" the market. It either lives or it dies, if you try to fix the market, it dies. |

Everything installed fine, but when I try to run the Miner I get the above error. Not sure why I'm getting that error. Can anyone give me a clue? I think the problem here is you're mining with an Nvidia 8400. Does it take 4 months to generate a bitcoin? |

How do I get in touch with Mt.Gox? They are closing all tickets I send to them without reading them. Automated. I'm really getting frustrated. I've 5200 dollars in that account and noone is helping me.
I suspect that if your account got hacked you no longer have $5200 in your account. |

what i don't get is why you don't consider people wanting to buy bitcoins to actually use them as a currency and spend them ?
Seriously? You think 200 little vendors is going to drive the current market cap? |

The guy that lost 25000 btc is still wondering why that site did not work. |

Coins were placed on the market at 20 btc to stop the price from going higher in attempt to stabilize. If you have evidence that this is true, I'd like to see it. Otherwise, you are speculating. Your evidence can be found in the charts and market dept. My only speculation is that someone planting an ask for 1300 bitcoins on the market is probably not an idiot and knows that it isn't going to sell with volumes as low as they are, people will place their asks lower than his and that market will stall, which is exactly what happened. And now a 1300 btc roadblock becomes a 5000 btc roadblock within a couple of days. And surprise, surprise the buyers dry up and the market heads south. |

This is pure speculation. It could be that someone just wants to sell off a large number of coins, or that people are skittish after the weekend's bounce.
It's not speculation. If someone wanted to sell 1300 coins they could easily break them up and sell them a whole lot faster. Coins were placed on the market at 20 btc to stop the price from going higher in attempt to stabilize. What happened? Volumes dropped and now the price is sinking. |

bought some bitcoins hoping to profit from another price spike but got bored at prices idling at $19 and things getting weird as time passed so I withdrew my money and bailed out before an inevitable crash. good luck to those staying in the game I agree this market manipulation is doomed to fail. You cannot "build up" buyers by putting an artificial ceiling in. No one is going to invest into anything that is locked in with the dollar. People invest in high-risk because it yields high return and yes bitcoins is high risk regardless of any stabilizing attempts and is likely to remain so until the volumes and market cap is up. |

It seems like there have been some artificial attempts to stabilize the market through the use of huge asks in order to drum up vendor adoption of bitcoin. I don't see how this can work, all you are going to do is scare away all the buyers. People buy bitcoins because they expect them to gain value, if you lock them to the dollar you might as well just keep your dollars.

Locked out of the FPGA development thread due to the new 50 post restriction.
I mentioned in the main FPGA development thread (by fpgaminer) that I have coded an unrolled sha256 using additional pipelining and was asked about resource usage. I am now compiling with the subscription edition Quartus II v11.0 with an evaluation license. The resource usage is around 44K LE in a Stratix IV (EP4SE530H40C2) for a single core and the clock rate achieved is 240MHz. This device should fit 4 SHA256 pairs with a hash rate approaching 1GH/s. The EP4SE820 should be capable of 2GH/s. I have found a system that uses 20 of these on a single card. Yes this would be expensive to buy (>$200K I assume) but much smaller size and less power usage / heat than a cluster of computers running 6990s, maybe as low as 1-2kW total?
As for the cheaper Cyclone IV (EP4CE115F29I7), resource usage is 62K LE (38K combinational functions, 44K registers, it seems Cyclone cannot combine them effectively) and clock rate is 134MHz. A single SHA256 pair with the additional pipelining would struggle to fit in this device, however I have another version which uses just the precalculation of H + K + W to improve clock rate, which will be smaller. I have found a card with 27 Cyclone IIIs, wonder how much that would cost...
Interested to hear what other people have achieved in terms of clock rate and resource usage.
$200k for 1 GH/s? That's a deal right there.. no for 20GH/s, and very low power usage. For that kind of money you can buy about 200GH/s through noisy over, power consuming, heat producing rigs. FPGA has a long way to go unless your rich and have an irrational desire to go green regardless of the expense. |

I'm planning to buy parts to make this rig: https://en.bitcoin.it/wiki/Mining_rig#One_ATI_5830,_Approximately_245_Mhash/sIn about a month. In a month will I still be able to get the same overall profit as I could with that now? I realize the difficulty is increasing which means you make less bitcoins, and therefore less money, but doesn't that also mean a relative increase in the value of each bitcoin which should even it out? There is going to a significant increase to the complexity later this week. Within a month there is likely to be additional increases. Hopefully the prices go up with the complexity but that is no certainty. You need to identify your risks and decide for yourself if it is worth it or not. |

I wonder how many people are punching themselves for panicking and selling around $10/btc.
