Bueno, para ser precisos, Gemini aún no esta operativo, será lanzado cuando finalmente salga la BitLicense, pero en su pagina solo puedes introducir tu correo para que te avisen cuando Gemini abra sus puertas.

Durante la caída de bitcointalk ha habido un fork en DRK (itsaconspiracy.jpg), lo relevante para BTC es que ese fork ha sido provocado por el código del nuevo bitcoin core 0.9.3, aquí dejo el anuncio: https://github.com/bitcoin/bitcoin/issues/5698

El Wall Street Journal anuncia que Coinbase será el primer exchange estadounidense de bitcoins:

First U.S. Bitcoin Exchange Set to Open - The Wall Street Journal

El articulo del WSJ es solo para suscriptores, así que lo pego en su totalidad (en inglés):

Quote
First U.S. Bitcoin Exchange Set to Open

By
Greg Bensinger
Jan. 25, 2015 4:34 p.m. ET
The virtual currency bitcoin is getting a very real boost on Monday, with the opening of the first licensed U.S. exchange.

Coinbase Inc., a startup backed by $106 million from the New York Stock Exchange, banks and venture-capital firms, said its exchange will offer greater security for individuals and institutions to trade bitcoin and monitor real-time pricing of the cryptocurrency.

The exchange could bring needed legitimacy to the currency, which isn’t backed by a central government and is traded over virtual exchanges, primarily overseas. Coinbase said it has insurance, offering traders some assurance that their money won’t disappear.

Bitcoin enthusiasts have been buffeted by the collapse of Japan-based exchange Mt. Gox last year—taking with it around half a billion dollars of investors’ money—and a security breach earlier this month at Slovenia-based exchange Bitstamp. The value of a bitcoin itself, determined by trading on existing exchanges, has fallen to about $240, from a peak in late 2013 of more than $1,200.

“To have an organized exchange that has the backing of thoughtful venture capitalists and investors addresses one of the main problems with bitcoin: its extreme volatility,” said Campbell R. Harvey, a Duke University finance professor who has studied cryptocurrencies. “Bitcoin has been sorely in need of something like this.”

Coinbase’s founders say they have been working for five months to win licenses from state financial regulators. They have regulatory approval in half of U.S. states, including large population centers like New York and California. For now, Coinbase can do business with account holders only in states where it has approval.

Coinbase will take a small percentage—likely less than 1%—of most transactions, said Fred Ehrsam, 26 years old, a co-founder. The exchange will initially be limited to users in the U.S., but Chief Executive Brian Armstrong, 32, said he plans to expand overseas.

Mr. Armstrong said he expected to attract both individuals and businesses looking to trade bitcoin. “Our goal is to become the world’s largest exchange,” he said.

Others are looking to open U.S.-based bitcoin exchanges, including Tyler and Cameron Winklevoss, the twin brothers known for their early feuds with Facebook Inc. founder Mark Zuckerberg .

Financial regulators, including the U.S. Federal Reserve, have been scrutinizing bitcoin recently. Benjamin Lawsky , the superintendent of the New York State Department of Financial Services, is working on a so-called BitLicense for firms looking to offer digital-currency services in the state; Coinbase is operating under earlier regulations. Mr. Lawsky’s plan is seen as a template for legislation in other jurisdictions, and it may give outsiders more confidence in the currency.

Bitcoins are created using high-powered computers that “mine” for the currency by solving complex mathematical equations. They are exchanged digitally either for currency, or goods and services. Ownership and transactions are recorded, anonymously, in a so-called blockchain, which backers say reduces the risk of fraud.

Bitcoin grew to prominence in recent years in part because of the ease with which it can be transferred.

Coindesk, which tracks the price of bitcoins, says 82,000 businesses accept the currency, double that of a year earlier, including e-commerce site Overstock.com Inc. and Expedia Inc., as well as many small retailers. The value of all bitcoin is $3.2 billion, according to Coindesk’s price index.

The NYSE invested in Coinbase during a $75 million round of fundraising that closed this month. Other investors include USAA Bank, the venture arm of Spain’s Banco Bilbao Vizcaya Argentaria SA, former Citigroup Inc. CEO Vikram Pandit and former Thomson Reuters Corp. CEO Tom Glocer. Venture backers include Draper Fisher Jurvetson, Andreessen Horowitz and Union Square Ventures.

The NYSE’s investment was intended in part to “keep an eye on bitcoin as it matures as a legitimate currency,” President Tom Farley said. “Any currency relies on its acceptance.” The Coinbase exchange “is an important step for the currency to become socially acceptable.”

Como allí no permiten comentarios.... lo pongo aquí.. Wink

Quote from: CINCO DIAS
Algunos fallos
Este sistema no es invencible y se han producido una serie de ataques que han hecho que la seguridad del sistema sea un punto que preocupe a muchos. Algunas de las plataformas de intercambio de bitcoins han sido vulneradas y ello ha provocado su cierre. Primero fue Mt.Gox, que cerró repentinamente su plataforma tras haber sufrido el robo de cerca de 750.000 bitcoins. Esto tuvo como consecuencia que muchos usuarios no pudiesen recuperar sus bitcoins.
Otra de las principales plataformas que ha tenido que echar el cierre es Flexcoin, también como consecuencia de un robo. Los hackers atacaron la plataforma y se llevaron cerca de 900 bitcoins lo que supuso la quiebra de la plataforma al no tener los recursos necesarios para la recuperación. Habrá que ver si finalmente el Bitcoin adquiere la relevancia y protagonismo esperado.

Resumiendo, Si falla alguna( s) casa de cambio, significa que la seguridad de toda la red bitcoin tiene fallos... FALLOS, del artículo en este caso, si que indican algo.. Indican desconocimiento, no solo sobre el tema tratado sino que también sobre los argumentos usados, considerar que un protocolo, o una moneda,  tiene fallos por que la seguridad de algunas casas de cambio presentan fallos, es erróneo... Se mire por donde se mire... El autor debe ser de la misma "escuela" del que escribió el artículo definiendo que Bitcoin fue un fracaso tecnológico, por el bajó de su precio.. Vaya enero mas "cargadito" tenemos!
