They have been down since Thursday July 3, 2014. It is an obvious hack. I didn't have anything for sale, but do have some coin in my KYC'd account. How are you contacting support? They have been silent since supposedly thwarting a D-Dos attack on July 3, 2014 (per their twitter and facebook). You have more at stake on Campbx than I do.

Although I haven't had any trouble with Campbx in the past; I am concerned. That chart where the price spiked is confounding. Let's get to the bottom of this.

Why an exchange would remain silent during an extra long outage is baffling. Their twitter and facebook seem to work, so let the customers know what is going on with their money.

LMAO: Campbx is back up - just now (17:30 EST). I hope your account is okay. Keep us updated.

MUST EDIT: The green bar is gone from the now up https://campbx.com/  I would avoid entering my credentials for the time being. I'm actually going to logon and attempt to withdraw some coin and will report back to this thread once finished. I swear I am damn near done with all exchanges.

UPDATE: Unable to login with known credentials. Site has minor differences that would only be known to regular users. Do not enter your credentials unless you want your account stolen - I can't confirm that my account was hacked/stolen; only that my login credentials are not accepted. My passwords are never less than fifteen random characters for all bitcoin related activity.

It is well enough designed considering they do not collect IPs or use cookies. It reminds me of web 1.01 sites from the 90's. I'm sure they could do better, but math guys aren't typically into aesthetics so long as the result and process are correct.

I've watched this with fascination. However, I do not think having money makes someone "bad". Solving a puzzle that is open to everyone is not "bad". I fail to see the logic. Once an individual reaches a certain level of wealth, should they quit trying to acquire wealth? It's not like the winner used child or slave labor to solve the puzzle - that would be bad. Your definition of "bad" is flawed.

In the early days of any new tech, scammers and thieves will abound. I'm almost done with all exchanges and am looking to circumvent this type of thing happening in the future. The immediate future will involve p2p with escrow. The longer term will entail very regulated businesses (in the US).

I'm sorry for your loss. The best thing you can do is learn from this. Ask yourself what attitudes you had at the time that facilitated your actions that led to your loss. Recognize these attitudes in the future and act accordingly. It may work out that your decision making was not flawed and the mistake could not have been avoided. Proceed with new knowledge and without fear.

I'm a long time user of Campbx and have a few folks under me as affiliates. I have never had a single issue with Campbx until the recent holiday (US only) weekend. They announced a D-Dos attack that was resolved on Thursday July 3, 2014 at 4:00pm per their twitter and facebook pages. The site was up and then back down again within minutes. It being a holiday weekend, and them being in the US; I relaxed and enjoyed my holiday.

It is nearly 4:00pm on Monday July 7, 2014 and not another word from Campbx. I've read about troubles with Campbx in the past, but I have literally had none of them. KYC'd in record time. Withdrawals processed immediately (btc), and a reasonable amount of time elapsed for fiat withdrawal (days with money order). I get cheaper fiat withdrawal fees and lower trading fees than standard users. All in all, I have been very pleased given the current, sometimes sketchy, nature of exchanges.

D-Dos attacks - or claims of them - have preceded exchange failures before. I don't have a lot of coin on Campbx, but I'd like to know if and when this will be sorted. Does anyone have any information? Four days is a while to be down in a 24/365 market.

EDIT: Campbx is back up, but many users are unable to withdraw BTC. One, at least, had trades reversed. I think they are trying to get this sorted. Still many users, including me, are unable to login to their accounts.

All coins were moved in a single tx: https://blockchain.info/tx/9e95c3c3c96f57527cdc649550bf8e92892f7651f718d846033798aee333b0c3

This is exactly what I did - very crudely. I would be a happy to help you with weighting your inputs. Bitcoin is evolving. Last year if we had some of the news we have had this year, the swings would have been MASSIVE. Things have changed. Consolidation is happening. Smart money is giving way to smarter money. The mining landscape has changed. The "killer app" is being built. I'd be happy to take a look at your parameters, variables, and weighting strategy and offer some foggy insight. No guarantees though.

I'm not a coder. I took both MIT's and CalBerkley's freshman and sophmore free online courses in order to teach myself python. Codeacademy helped too. I am (was) a physician by trade. I am good at the maths, but it's all in my head (and chicken scratch notebooks). Python is good at making brain maths = screen maths without all the heavy lifting. I tried to make this script autotrade (something I obviously had no clue how to do) for me and created a bad loop. I did not back up my work. I was running the script and trading based on my number. Once I incorporated the trading API's from various markets, I couldn't go back. I lost $4400 equivalent in one day because I thought it worked.  I no longer actively trade. 

Specualtion and speculators are essential for any free market. I'd like it if the people retained control of the bitcoin market. It is important for regular folks to trade in novel markets in an internet "outcry" sort of format. Centralization of mining is not a crucial variable as many have speculated. Centralized speculation on the other hand, could be devastating for the common fellow.

Warren Bufett isn't exacty a bitcion enthusiast, but his words ring true: "It matters not when an event will occur so long as you know that it will occur." Abide.

Does anyone else think that we need a "Trusted Buyer" system integrated with bitcoin and escrow? Fuck a trusted seller. Trusted sellers can command higher prices. In the case of the "Trusted Buyer", sellers can reduce prices with the expectation of reduced headaches (disputes [bitcoin escrow] - or chargebacks in the case of PayPal). I'd expect something like this on the market soon that will rival ebay (minus the "PowerSeller"). A good bitcoin seller gives an accurate description of their product and delivers as agreed. A trusted buyer releases escrow immediately if the terms are met.

I think the biggest hurdle to adoption for debit purchases (cash, bank account, bitcoin) purchases is third party trust; which unfortunately we still need to some extent. Escrow solves this. It is essentially what Paypal does and gets paid handsomely. The second hurdle is for the seller to trust that he/she will actually get the agreed upon price in a timely fashion. It's going to happen.

Things like OpenBazaar are likely the future, but running a client that manages financial transactions on a PC is not going to be in any common man's wheelhouse anytime soon. I've been in bitcoin since early 2013 and still refuse to run QT, multibit, or any other client on my desktop. Most consumers will not do this.

Folks tend to think that Ghash, etc having a major control over the network is a big deal. Ghash doing anything malicious is the equivalent of slaughtering the golden goose for a single meal (quite literally). People complain about the anonymity of Ghash, et al.

Isn't that why many of us got into bitcoin to begin with? I want any pool or individual to be anonymous so long as they choose. If the government comes knocking and stealing, they need to try and find the source. I'd rather that source not be found.

Does that instill fear and doubt in the minds of the community? Of course it does. Trust Ghash et al to uphold the integrity of the network. There is no good reason that a pool mining something of value would intentionally destroy said value....EXCEPT this:

If I was asked if the miner manufacturers first use the machines they make at a lower difficulty level while taking pre-orders to make the next gen model - with which they will do the same...and-den...the miner makers send the already used units (see damaged heat sinks and obvious signs of wear when actual consumers take delivery of the pre-ordered unit that has obviously gone through rigorous testing <obvious use>; and now use the pre-ordered units to mine at an advantage to the previously pre-ordered units - I would say emphathically YES this happens.

Don't ask me how or "link" or any other shit like that. It fucking happens, and you are stupid if you think it doesn't happen. It takes a blind fool to not realize this.

51% attack = no big deal

Taking pre-orders to finance a mining operation, only to sell the miners later to the poor souls that pre-ordered = bullshit, fraud, not nice, etc.

Some people grow coffee. Some people buy coffee. Some people sell coffee. Some sell coffee futures (contracts). Quite a few people drink coffee. Understand the difference, but apply this truth to a non-renewable resource like bitcoin and you will understand why people do what they do.

I'm really enjoying reading this thread. It appears that you have a nice work in progress that may develop into a useful tool.

Back when I was still trading/speculating vs. hodling; I wrote a python script that was intended to do something similar - warn about reversals. Several variables were used and assigned a value of -1, 0, or +1 (like counting cards in blackjack). The scale was -7 through +7. It worked pretty well before I broke it. I'll be following this thread with some interest. Good work.

Even though I no longer speculate in the short term, I still enjoy reading this sub and marvel at the detailed analysis that many of you guys do. Quantifying and predicting new markets is valuable beyond the scope of just bitcoin. Tip: weight your variables, add assumptions (be willing to remove them if they prove wrong), and be very critical of your process. Thanks for posting.

At first I "tradefarted" on the news of the auction. Immediately, I began talks with other much more savvy investors than me. Pretty much everyone with more experience indicated that the news of the sale is bullish for bitcoin.

First, it fully establishes that bitcoin is an item of value that has obviously matured since the seizure. The Feds are selling it for Federal Reserve Notes for crying out loud! It also establishes bitcoin as property (they do not auction cash), which I happen to think is very tax advantageous for average US citizens. Second, there is no way this much coin could move on the open market without effectively raising the market price substantially (if only for a few moments). A $2,000,000USD buy on Bitstamp would raise the price to about $645 or 10+% right now. That's about what 3000 coins would go for right now. Third, long term speculation on bitcoin is pretty f'ing bullish.

All that said, if the capital was available; I'd bid on all ten blocks of coins ranging from %25 under market to %25 over market at the time of the bid. Most of the big players will be employing this strategy.

I've read many people believing that this is an open auction with an auctioneer. It's not. It is a silent auction with bids submitted by email. There are ten blocks. You post a $200,000 deposit and submit the bid(s) by email. You get one bid per block. There are 10 blocks. 3000 coins per block on 9 of the blocks, and two thousand something or other on the tenth. If you post the $200,000 deposit, you can bid on all 10 blocks. If you win a block or more than one block, you had better be able to pony up very quickly or risk losing your $200K.

A tradefart is when a hodler sells on news that he/she has not yet analyzed. The tradefarter then buys back at market price upon realizing that they are an idiot. A wet tradefart is when the short term assumptions come true only to be counterbalanced by the reality of the market conditions.

Looks like the exploit and proof of concept already exist. Saw this (http://www.reddit.com/r/Bitcoin/comments/27hyyl/how_i_stole_over_100_btc_from_thieves/ ) a couple of weeks ago and thought it was BS before reading the OP. My guess is that the exploit exists and is being used. I'm pretty sure that the guy that actually got refunded is a member here (nekomata).

FWIW: I suggest using blockchain.info (hot wallet), QT (heavy users), and cold storage (savings).

Please go here: https://bitcointalk.org/index.php?topic=650229.0

I should have looked for this before starting this thread: https://bitcointalk.org/index.php?topic=650238.0

I will point folks here. Oh, and I'm down for $20,000.

Someone (-someone-Hamilton) in another thread suggested getting together to buy the SR coins that are to be auctioned off at the end of this month. I propose that we pool our resources, perhaps forming an LLC (I'm no attorney), to grab at least one of those 3000 coin blocks. I'm down for $20,000 (10% of the deposit). I think the market price at the time of the auction will be much lower due to this news. We should be able to get the auctioned coins below market value at the time of the auction.

Please pledge how much you would be willing to contribute to get the coins and what maximum bid value you would approve. No BS answers please. FWIW $1M winning bid = $333.33 / BTC. Think about it.

I've heard this hack works on many gas station/grocery store ATMs as well. Folks will walk in with a blue collar shirt on to "service" the ATM, get admin control, and change the amount dispensed ($100 for $20 withdrawal). It's fascinating how much trust we give the banks.

KYC is not required at some exchanges so long as certain account thresholds are not met. It's usually $1000 or so.

I can track mixed coins fairly easily with crude tools (like <ctrl> "f" - yes on my keyboard) using taint analysis on blockchain.info. One fellow recently won a bounty from blockchain.info for using a more sophisticated, but still fairly crude data analysis tool that he wrote himself to discover the id of a mixed Tx. If I cared about concealing coins, I would use the exchange method.

I'm finding the same thing. And r/bitcoin is no different. The admins will heap together downvotes on stories that they would prefer to not see on the front page or just delete threads altogether. Don't call something a community when it is really an oligarchy. Information should be left to it's own merits, and admins and mods should see only that the forum rules and etiquette be followed. Information filtering/censorship is wrong and damaging for the community.

It's good that schools got computers for the kids to learn on in the 90's, but you should have to pass an internet ethics course before being allowed to use the internet . The conversation can deteriorate into what sounds like Halo or Call of Duty gaming chat rather quickly. It is frustrating.

Disclaimer: I still read reddit.

I respectfully disagree. I think bitcoins are for all three. Spend and rebuy immediately. Cold storage savings is by proxy longer term speculation. I think people that are holding losses in BTC are reluctant to spend to avoid taking a loss. People sitting on a gain are reluctant to spend due to the capital gain (in the US) that must be realized. I try to buy everything other than perishable grocery items, gasoline, booze, and tobacco (I know what else is there right?) with BTC. Show the merchants that we spend, then buy back some more BTC to replace that which was spent.

I like Western Union / MoneyGram with a security question and "no ID". I believe there is a $500 limit to the no ID Tx in the US. Beware the customer service clerk will often be befuddled. Take this cash and load on any of the prepaid cards that can be used online. You must show ID when getting any of the "reloadable" cards. If you are shopping online, why not just use BTC to buy what you want, or use gyft.com and the like?
