Can meet in the Santa Monica area or general vicinity. Would like to do this in the next day or two.

Posted it on Ubitex as well.

This thread is completely worthless until someone posts the mathematical odds of this happening (relative to how long bitcoin mining has been taking place and/or current difficulty rates and hashing power).

What's the exact amount of the large transaction? Is this article accurate on that part? If so then that's not an internal Mt. Gox transaction making it even more likely than it already is that they're lying about the extent of this.

Re: Someone spamming the MtGox userlist with TradeHill referral spam

I admire his hustle, but this guy is a real fool.

My guess is Trade Hill has this guy's real name, etc.

What he did is very illegal, and there's a reason spammers don't tell you who they are. YOU personally can sue this guy (for something like $16,000 I think). Of course odds are he doesn't have enough assets to cover even 1 settlement, let alone thousands, so you're not going to get rich off him but he is probably in a world of hurt from this.

$13 is the higher end, in my opinion. You guys really think there's more people itching to buy than itching to sell?

Can you please suspend whoever's account this is for their blatant spamming?

tradehill.com/?r=TH-R15683

I'm sure you've heard, but they emailed every Mt. Gox customer with their referral code.

On further inspection it looks like maybe Facebook just thought my really long wall post about what is happening looked weird.

Facebook problems?
by

on 19/06/2011, 22:21:59 UTC
So, for starters, my mtgox password is something I ONLY use for mtgox.

My Gmail was already locked down (supposedly they're doing this to everyone on the list as a precaution).

I just tried to post on a Facebook wall though and got this message from FB:

Account Safety
It looks like a link you pasted into your address bar caused unintentional activity on your Facebook account.
The link may have looked like this:
javascript:(a=b=document)...;void(0)

Don’t worry, your account is safe. In the future, never paste suspicious-looking links or text into your address bar. They could cause spam on your account.

If you did not intend to do this, please click Cancel.

Is this related? I'm on Chrome/Win7 if it matters. Just ran full virus scans yesterday w/ MalwareBytes and MS Forefront.

Same here.  Good luck cracking my password.

I'll give you a headstart.

Listed salt $1$ZBJdbkqZ$
Listed hash MD/Ln/Ro/cOFIPpWYMHpA.

My password starts with a letter, ends with a number, has a symbol, and more than 15 characters.

If you crack it and post it here I'll send you the remainder of my mtgox funds ($500)

1. Where'd you download/get this info?

2. Assuming I know my password is one of two things can I figure out what it is using this?

Not sure why but my IP was banned yesterday so I logged in from a different location (worked fine) and changed my password. I'm not sure if my old password or new one is in the data that was stolen. Either one is ~18 characters. Am I pretty safe either way or is it true that these aren't as well salted as mtgox claims?

Re: 1.2 Ghash for sale

One of the biggest problems with these lease deals, and I've talked about it before, is that you're taking on all the risk without getting the full benefit.

If bitcoin crashes hard then you basically lose everything. You don't even have salvage hardware to fall back on. If bitcoin skyrockets then you'd have been better off buying them. So already the only scenario this pays in is if they stay relatively stable and in that case you need some really good returns relative to buying your own rig to make it worth it since you're taking all the risk. Not only do you not get better returns with this deal than buying your own rig you actually get worse.

Not a big deal, but my preferred display would be "last" price.

Also, the price doesn't quite fit on mine. I can screenshot if you want, but mine is displaying:
19.9'
I think that last part is the cut-off part of a 7.

Ok, so better power supply. I can figure that one out. What can I do on cooling?

As far as miner/parameters the plan is to do whatever maximizes Mhash/s.

I've got 2 5970's on hand (lucky me). Would something like this rig work just swapping the 5850s for 5970s?

Re: New miner-centric site with hopes to stabilize the BTC economy

I skipped the thread, but hopefully someone has pointed out that what you're suggesting is a cartel. You're the millionth person to invent such a thing. They sound great in theory, but they don't (generally) work.

The reason is that it's profitable for people to cheat the cartel and therefore, inevitably, someone will. You're trying to resist the natural forces of the market.

Cartels can work when they're made up of a very small number of people (the handful of controlling interests in OPEC, the only two gas stations in a small town, etc) and/or when there are effective methods to punish cheaters who must be traceable. Bitcoin mining is almost the perfect example of a scenario in which cartels can't and won't succeed.

Rig help

I read the whole noob FAQ, but I'm trying to find some solid resources on building the pieces are your video card.

Here's what I'm trying to find out:
1. The typical cost of the other components
2. Typical total wattage of the other components
3. How much this is dependent on the specific video cards you're working with

Can anyone help me with these or point me toward a good resource?

Mine definitely didn't go through after 6, but I figured it was just the time it took for them to process it or something. If that used to happen right away then yes, I guess they've changed it.

Re: Analysis of Buying a Rig for Mining

Hi, I'm a confused newb here. This Analysis doesn't make sense to me. My understanding is that there is a fixed amount of BTC to be mined each week. The difficulty is used to keep that fixed amount in check. The difficulty is currently increasing because the amount of rigs are increasing. The reason the amount of rigs are increasing is because there is big profit in mining right now. However, if the difficulty was increased so much that it was clearly not profitable then wouldn't most people shut down their rigs bringing the difficulty down? By this analysis, it shows that even when the difficulty is so high that it's clearly not profitable people will still bring new rigs online. Why would anyone bring new rigs online when the difficulty is clearly to high to make a profit?
Like I mentioned before, I am a complete newb here so I'm sure I'm missing something important in my understanding about how this works. Thanks for any clarification.

The problem is you end up competing against people who:
- for some reason aren't paying for their power, or
- wouldn't normally enter because the profits are so low but already own the equipment so just keep it going
or both.

The long-term equilibrium difficulty will likely be below the break-even point for folks paying for both electricity and hardware depreciation. Even if it's above break-even, if you're only earning 10% that's pretty crappy for: tying up capital, spending your time, and taking on risk of loss.

Botnets
by

Curious if anyone can guess a VERY rough ballpark on this.

How much total hashing power do you think an existing large-scale botnet could generate if it were targeted at mining? Assume that some non-zero number of the victims have decent video cards that are being exploited.

Revisit your calculations.  You might be thinking "It's no problem, at the worst, I break even and get the hardware for free within X days."  You need to run your calculations for the next 3 months assuming MINIMUM +90% difficulty per increase, and a $10 BTC price.

I'm the first to convince people to project conservatively, but this is silly.

Do I recommend projecting your rig at $10/BTC? Absolutely. It needs to be profitable at that number.

Do I recommend projecting 90% difficulty increases? Absolutely (at least in the short term). It needs to be profitable at that number.

BUT, there is no way you'd see both $10 AND 90% increases. At the current price I would think we'll see 50-70% difficulty increases in the short term. At $10/BTC I think you're looking at more like 20% in the short-term and 5% in the long-term.
