Bitcoin Mining Boom Sputters as Prospectors Face Losses
The bitcoin mining rush is sputtering.
Speculators, known as miners, use powerful computers to solve complex software problems and verify transactions to unlock new bitcoins. They’re finding that the enterprise isn’t as profitable as it once was.
Drawn by the virtual currency’s jump in value last year, digital prospectors have turned the mining industry into an arms race as they buy expensive computing equipment and gobble up electricity. While that worked well as long as bitcoin’s value kept rising, smaller players are now being crowded out by bigger competition, high utility bills and declining prices.
“If you mine at the moment, you have to be very lucky to get anything,” said Mehmet Vatansever, who bought $16,000 worth of mining computers in February to chase after new bitcoins. “It’s a very difficult business.”
Mining, a nod to the excavation of minerals and metal ore, is entirely digital and part of bitcoin’s design, so that the money self-regulates supply and prevents out-of-control inflation. The mining process gets increasingly complicated as more bitcoins are created, driving demand for computing power.
Bitcoins, which jumped to more than $1,200 last year from $12, were trading at about $420 apiece yesterday, according to the CoinDesk Bitcoin Price Index, an average of prices across major global exchanges. China’s tighter controls on alternative currencies, the implosion of the Mt.Gox exchange and a U.S. Internal Revenue Service ruling that bitcoins should be taxed as a property have all weighed on the virtual currency.

Bitcoin promoter Shrem indicted in NY for money laundering
Prominent bitcoin entrepreneur Charlie Shrem has been indicted by a federal grand jury in New York on charges of funneling cash to the illicit online marketplace Silk Road.
Shrem, known as one of the digital currency's most visible promoters, is accused of conspiring with a Florida man, Robert Faiella, to sell more than $1 million in bitcoins to the users of Silk Road despite knowing that it would be spent on illegal uses like drug trafficking.
Both Shrem and Faiella face charges of money laundering, conspiracy and failing to file suspicious activity reports with government banking authorities, according to the indictment filed by Manhattan U.S. Attorney Preet Bharara.
Shrem's lawyer, Marc Agnifilo, and Faiella's lawyer, David Braun, did not immediately respond to a request for comment on Monday.
Federal authorities shut down Silk Road last year, and prosecutors from Bharara's office have charged Ross William Ulbricht with operating the site under the name "Dread Pirate Roberts."
Shrem, 24, was arrested in January and stepped down as vice president of the Bitcoin Foundation, a well-known trade group, soon after. He was previously CEO of BitInstant, a bitcoin exchange company that enjoyed financial backing from the twins Cameron and Tyler Winklevoss but closed last year.
Bitcoin is a digital currency, not backed by any government or central bank, that fluctuates in value according to its users' demand. Users can transfer bitcoins to each other online and store the currency in digital "wallets."
Authorities have vowed to pursue those who use bitcoin to complete illegal transactions, while regulators are still grappling with their approach to the nascent currency.
The recent failure of Japan's Mt. Gox, which filed for bankruptcy after apparently losing hundreds of millions of dollars worth of bitcoins, has underscored concerns about the currency's long-term viability.

The Hunt For The Creator Of Bitcoin Keeps Coming Back To One Guy
The Hunt For The Creator Of Bitcoin Keeps Coming Back To One Guy — And He May Be Hiding In Plain Sight
This morning, students at Aston University in Birmingham, England, claimed they'd narrowed down the identity of Satoshi Nakamoto, the pseudonymous creator of Bitcoin, to a writer named Nick Szabo.
Forty forensic linguistics majors looked at similarities in language used by Satoshi in his original Bitcoin spec paper and that used by 13 people "regularly referred to as suspects."
Matches with Szabo were the strongest.
Dr. Jack Grieve, a lecturer in forensic linguistics at Aston, said:
"The number of linguistic similarities between Szabo’s writing and the Bitcoin paper is uncanny, none of the other possible authors were anywhere near as good of a match. We are pretty confident that out of the primary suspects Nick Szabo is the main author of the paper, though we can’t rule out the possibility that others contributed."
This is the latest instance in which the hunt for Satoshi has landed on Szabo. In December, an anonymous blogger created a WordPress site with the explicit purpose of publishing his linguistic match findings between Szabo and Satoshi.
The blogger doubled-down on his claim a month ago, saying his latest research "confirms that Nick Szabo’s writing matches the Bitcoin whitepaper, not only in the expressions it uses, but also on hard-to-fabricate style metrics."
For a while Hilary Sargent, now with the Boston Globe, was tracking possible Satoshi candidates on her ChartGirl blog. Szabo had figured on the top of her list because, among other things, he'd written about a theoretical technology called "Bit Gold," which bears an uncanny similarity to Bitcoin.
Szabo's personal website contains papers on a galaxy of different topics, including ones key to Bitcoin's technology. Here's a sample of his writing on "Formalizing and Securing Relationships on Public Networks":
All public key operation can be performed inside an unreadable hardware board or smart card on a machine with a very narrow serial-line connection (ie, it carries only a simple single-use protocol with well-verified security) to a dedicated firewall. This is economical for high traffic servers, but may be less practical for individual users. Besides better security, it has the added advantage that hardware speeds up the public key computations.
And here's a cut from the Bitcoin spec paper:
As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner.
Szabo might be hiding in plain sight. Gavin Andresen, one of Bitcoin's core developers, told Business Insider in an email that he had attended the Princeton Bitcoin conference with Szabo in March. Business Insider has tried calling and emailing several phone numbers and addresses associated with Szabo over the past few months to no avail.
In November 2011, Wired's Benjamin Wallace said Szabo had denied it, though it was unclear where and how this occurred. Szabo's most explicit disavowal came in a May 2011 blog post in which he wrote the following on the advent of Bitcoin and what made it special:
Myself, Wei Dai, and Hal Finney were the only people I know of who liked the idea (or in Dai's case his related idea) enough to pursue it to any significant extent until Nakamoto (assuming Nakamoto is not really Finney or Dai). Only Finney (RPOW) and Nakamoto were motivated enough to actually implement such a scheme.

Mt. Gox suitors seek support to save bitcoin exchange
"A group of investors seeking to buy Mt. Gox has launched a website to garner support from creditors of the bankrupt bitcoin exchange to prevent a liquidation of its assets."
It never ends
would like to believe that it is possible (and that that way I can get back what I have lost) but I do not believe anything any more when Gox is involved in any way
