This 50 post limit is pretty clear attempt at curbing the discussion about "Bitcoin bubble" in Economics and Bitcoin Discussion boards.

Very classy move to label people who think the current USD value of Bitcoin is a bubble as trolls...

It was pretty obvious that there was an organized attempt by some outsiders to spam the board with panic posts from brand new accounts with <5 posts.

The exchanges could implement stop limits.  But it is up to them.  Dark pools are the big problem I think.  They are hiding the real depth of the market.  If big orders move the market, so be it. 

So with dark pools you don't get to see the USD/BTC exchange that is being done right? Has anyone out there analyzed data from the block chain? I guess that wouldn't help shed any light on dark pools since you don't see the USD portion of the transaction right? How would one get in on a dark pool in mt. gox? Do the people in a DP get to see the ask & bid?
203  Other / Beginners & Help / Should exchanges have breakers? on: June 12, 2011, 06:06:11 AM
The drop today had me thinking. Should exchanges automatically halt trading if price changes more than a certain percent in a small enough time window, say 5 minutes or 10 minutes?

I'm guessing there are a lot of people with massive amounts of bitcoins hoarded. Whenever the price rallies and one of them decides to take some profit they can crash the market. With the market this shallow this kind of cycle can only act to scare off more mainstream audiences before it ever gains significant adoption. What do you think? Mt. Gox, c'mon.
204  Other / Meta / Re: The sensible way to cut down on forum spam.... on: June 12, 2011, 05:54:08 AM
The captcha and email verification would not work to deter all the spam posts. Maybe reduce it a little but not entirely. All the posts were from people, not bots, who wanted to fuck with the community for some reason. Whatever they were doing wasn't having any impact but annoying people who wanted to read the board. The price drop has been attributed allegedly to one person selling a huge cache of old bitcoins.
205  Other / Beginners & Help / Re: Wow! 8083BTC Bid at $10.70USD on MtGox! on: June 12, 2011, 05:31:11 AM
You know, that could very well be the guy who just unloaded the massive amount that caused all the panic. That is exactly what i would do if i held enough coin to influence the market so much. sell tons high, drive prices low, people panic which drives prices lower, then you buy back in at the new low rates with massive profit. Granted, this would not work if people had bought into the system because they love the ideology of bitcoin rather than buying in because they love the idea of themselves getting rich fast, because then they would not have sold out of fear as it dipped.

If what you're saying were true, that person would have to be either really dumb (to sell high and buy low, hoping the market would climb back high enough and stay there long enough for him to recoup his losses AND make a profit on top of that), or really confident that he could manipulate it into going back up to take his profit.

I'd lean towards the former.

You could simply google "bitcoin USD exchange rate".

But to humor you, here's just one of many places you can get the rate: http://bitcoinwatch.com/

I volunteer to help with this as well. You can check out my previous posts from before the 50 post rule was enacted. My posts were constructive, and I also posted at least 3-4 times ragging on the annoying incomers trying to spam with garbage panic posts and stuff like that.
208  Other / Beginners & Help / Re: Newbie restrictions (Please discuss forum policy here.) on: June 12, 2011, 04:59:33 AM
I'm glad the policy was put in place. I encouraged this in the meta section and unbeknownst to me the policy would affect me! I can't post outside the newbie section since I too have less than 50 posts. I think the ones I have been making have been positive contribution to the community for the most part. I'm willing to follow the rule if it means getting rid of the annoying influx of chicken littles screaming "the sky is falling".
209  Bitcoin / Mining / Re: Bitcoin difficulty not making mining worthwhile. on: June 12, 2011, 01:13:12 AM
I Built 30 rigs, each with 3 x 5830's which all and up cost me 15k which I purchased on credit cards at close to 20%. I am not making much money or bitcoins since the difficulty has gone up, I would have been quite well in the clear if I sold my bitcoins at $30 but I still have them, I don't want to sell them under $15.

Is the price of bitcoins going to go up, if so I will be alright but I am uncertain if I can continue to generate bitcoins in a profitable way. I still have to pay off the credit card. What do you guys think?



First, I call shenanigans, because no one would be foolish enough to invest 30,000 in bitcoin mining without trying it out on a small scale first. Second, asking if the price is going to go up is pointless. If anyone knew the answer with certainty they would buy up all the bitcoins they could right now so they could sell them if/when the price went back up. Third, you paid way too much per Ghash/sec if you really spent 30 thousand!

You might have to start considering whether or not you should start selling the hardware. Your chance to make a profit in this still exists if you got the video cards at a decent price. There are tons of people who will pay inflated prices for them right now.

What jumper? What setting is this jumper supposed to control? And is the jumper on the video card or on the motherboard?
211  Other / Meta / Re: The solution to the moron problem. on: June 11, 2011, 06:33:25 PM
I would support this. The forum is becoming cluttered with annoying posts from people with <25 post count. A ton of them are people trying to fabricate panic.

I've been on several other message boards where new users must have 10 or 20 post count before being able to post. Or they can only post in certain areas. Point taken about topic creation being a useful tool to the community but it's a tradeoff if you want to keep the quality of the message board high. If not, eventually someone will start a board of higher quality and people might migrate from here to there.

Value of bitcoin is gonna fall. The sky is falling. Just when I found something to do...now they take it away. Land of the free my ass.....

http://www.tribbleagency.com/?p=8070


Your first post. This poster is yet another of the swarm of people trying to cause panic.

There is no source that anyone is drafting legislation about bitcoins. All that happened was Schummer and another senator sent a letter about Silk Road, which mentioned bitcoin as the digital currency being used on silk road. Then every blogger and news site for some reason picks on bitcoins instead of the silk road aspect.
213  Bitcoin / Mining / Re: Botnets on: June 11, 2011, 03:34:44 AM
I think you could not really pull a GPUminer on bots - that usually need drivers installed correctly etc and it really slows down system performace - I think it would slow down their computers too much so most of the victims would simply buy new hardware.

However, I'm administering a Computer pool with 80 machines here for work, and thos machines have to stay on at night but theres no one being able to use them, so what I can tell:

CPU: Intel Q6600 -> 4 MHash/s/Machine
GPU: GF 8800 GT -> 25 MHash/s/Machine

that makes roughly between 25 and 30 MHashes per machine, for me it's about 2GH/s, but of course a large scale bot network could do much better.

no one will notice the thousands of extra money being spent on power or anything

good luck with your job

Lol sounds like someone is jealous.  This is a great way to utilize PCs that are otherwise wasting power doing nothing.
214  Economy / Marketplace / Re: What's a fair price for 1.1GHash (sub-letting mining)? on: June 11, 2011, 01:38:21 AM
The reason vlad sells contracts in the first place is because he knows that in four months the returns will be so tiny from mining and he would make more money from people purchasing contracts rather than he could make himself by mining.

His prices are also ridiculous. Last time I checked his monthly charge of ~400 euro is around $700USD, for ~1Gh/s/month. That's more than twice what it takes to build a machine capable of the same mining power yourself. At least going by the prices I saw in his post (I only looked at it today), the only people paying him must be those who haven't done the math themselves. And what does it say to you when someone goes around charging people for various things related to a fad instead of putting his money where his mouth is and mining for himself? I'm sure he's mining too, but he's making a killing by charging people crazy prices and then either pocketing the profit or putting it into his own hardware. Even if the market crashes he can sell the hardware and still make out really well. I can't say there's anything wrong with what he's doing, just not sure about the judgement of anyone sending him money.

NOTE: i'm basing that solely on the 400euro/month price i saw in his thread today. Maybe also everything costs more where he lives than where I live.

I would not run this without the source being released. How do oyu know he's not stealing 1% / 1/2%, 1/4%, etc, of your compute cycles? Or some other nefarious thing?

Not sure why you think he's a troll, but there is at least one 8 slot motherboard: MSI Big Bang Marshal.
217  Bitcoin / Mining / Re: Reinvest some gains in mining! on: June 10, 2011, 12:21:56 AM
Why not just set up a BTC mining non profit? Need 2 things:

1. Mining clients that can alternate between all available pools automatically. So like a distributed mining proxy pool. (distribute that to everyone will help security overall as people get bennies of large pool + danger of too much power in single pools is reduced). 0.025% (quarter of a percent vs. 3.00% for deep pool) of mining through this pool of pools goes towards the BTC nonprofit.

2. BTC mining non profit. Team of guys in each city get together (would work best if they were in the same city) to set up mining operations. Multiple per city, even better, but efforts would need to be coordinated. After their fund reaches acceptable starting point they start mining, and all profits go back towards mining. Maybe a cap on mining power for each such team, to spread out power for a more robust network. A way of halting funding once each team reaches self sustainability would be needed as well.

Just a thought.
218  Bitcoin / Mining / Re: Best Bang for the buck mining rig, please recommend parts on: June 09, 2011, 11:59:22 PM
Please link me if there is another post like this.

I was thinking of building a mining rig and need recommendations on the parts. I want to know the best bang for the buck. I will buy used only if it is easy to buy the components used and quickly. If you can send Newegg links for the recommended parts that would be great also.

Please list if it is better to go with 2 3 or 4 video cards, or 2 separate computers with 2 video cards each.





Maybe do your own research? There are already tons of other similar threads if you just search.
219  Bitcoin / Mining / Re: Renting GPU power on: June 09, 2011, 11:38:07 PM
1K for 2GHash/sec for a month wouldn't be worth it.

Worked out even a 'bad' case scenario.
Assuming BTC drops to $25 and stays there for the whole 30 days.
Assuming a 50% increase in difficulty every time for 3 periods of 10 days each.

After 30 days you would have mined over $2100 worth of BTC.

So unless the price of BTC drops significantly.  It wouldn't be worth it.

If you take todays BTC with a zero increase over 30 days.  With a more believable but still HIGH 33% increase in difficulty, you'll be at $3300.  Bad for the miner for only 1K.  And my numbers gets even worse for the hardware owner if I add in the electrical costs. 

My personal risks vs reward breaks even at $4k/month @ 2GHash/sec.  With these numbers, it'll be $5k/month before it's considered.

Well again you're missing my above point. The reason you can rent for less than the price of what you could mine yourself is because of re-investment.

Really the price of renting GHash should be set only at the cost to add an additional Ghash of mining power.

You should be able to add 2GHash of power to your network for about $1600. $2000 max if you're really bad at pricing out parts. So that'd be about right for a month of mining (figuring you'd normally pay off a new rig in a month).

I don't think that's quite accurate. You are either ignoring the currently inflated prices of the graphics cards it would take to build such a system, ignoring some of the parts required (extender cables, ram, hdd, cpu, mobo, case, shipping, etc), under-powering the PSU, or assuming that everyone will overclock (which I would argue you shouldn't do because people need an apples to apples basis when discussing hardware power/costs).
220  Bitcoin / Mining / Re: Rackmount cases that can fit 4x GPU? on: June 08, 2011, 08:31:49 PM
Aerocool PGS RS-9 ; ) Silentium PC Gladius 600   ~70$ each

Will either of those fit in a rack? They look like normal ricerocket compgeek desktops.

They are. With air sucked in from the side, so they loose cooling efficiency.

Ah, the OP asked for cases that fit in a rack.
