"Hey! I’m Andrew Wilkinson, founder of MetaLab. In December, my friend Rajiv, founder of Sparklit, and I started getting really excited about BitCoin. We both have full-time jobs running our companies, but we think Bitcoin is super cool, so when we heard about the Robocoin bitcoin ATM we bought one for our hometown, Victoria, Canada. We figured it would be a fun little side project and a good way to help move Bitcoin forward."

As Russia's ruble hemorrhages value, more than 40 percent of Russians are unable to explain why the currency is depreciating, a poll published Friday showed.

The euro's exchange rate against the dollar will fall to $0.95 by 2017, taking the single currency back below parity for the first time in more than a decade, according to a report by Deutsche Bank.

After long remaining mostly mum on Bitcoin, Microsoft’s legendary co-founder Bill Gates has spoken. At the Sibos 2014 financial-services industry conference in Boston, America's richest man just threw his weight behind the controversial cryptocash. Well, at least as a low-cost payments solution.

Dollars, euros and pounds are easy to visualize: They’re physical objects. Being digital, bitcoins aren’t tangible -- which has become a boon for George Frey. “I’ve sort of cornered the market on bitcoin photos,” the Provo, Utah–based photographer says in the November issue of Bloomberg Markets magazine.

I decided to see how practical it would be to mine Bitcoin with pencil and paper. It turns out that the SHA-256 algorithm used for mining is pretty simple and can in fact be done by hand. Not surprisingly, the process is extremely slow compared to hardware mining and is entirely impractical. But performing the algorithm manually is a good way to understand exactly how it works.

This week, PayPal took its first venture into the world of all-digital money. Merchants can now start accepting Bitcoin as payment.

In the digital drug trade as in the physical one, taking out one kingpin only makes room for another ready to satisfy the market’s endless demand. In the case of the FBI’s takedown of the Silk Road, the latest of the up-and-coming drug kingpins is far more evolved than its predecessor—and far less principled.

Four MIT students behind an award-winning Bitcoin mining tool will face off against New Jersey state authorities in court today when they attempt to fight back against a subpoena demanding their source code.

Last week, for the umpteenth time, Americans were called to the altar of reason after a study revealed that it now costs the U.S. Mint 1.6 cents to produce a penny. This was actually good news — last year the penny cost 1.8 cents to produce because of the high price of zinc — but it was yet another call to arms for those hoping to rid the United States of its tiny copper burden.

In the first interview with Mt. Gox’s Mark Karpeles since Japanese police launched an investigation into his bankrupt exchange, he says he’s just a regular geek—and that he’s in danger.

Russian authorities told people not to panic on Tuesday as the battered ruble plunged to record lows, floored by tensions with the West over Ukraine, new sanctions and falling oil prices.

In November of last year, I wrote that bitcoin had a China problem. With the BTC price tripling in a two month span to over $1,000 around that time, and BTC China surpassing (the then still solvent) Mt. Gox as the world’s largest exchange by volume, it was clear that China was exerting increasing influence on the price and stability of the bitcoin market.

A small but growing — and surprising — number of workers are rejecting Canadian dollar salaries for bitcoin, according to a Waterloo, Ont., payroll firm. Wagepoint CEO Shrad Rao said his firm came up with the cryptocurrency payment option in November last year as a side project and did not expect any take-up.

The Russian rouble fell to a record low against the dollar as investors fear further sanctions against the nation. The rouble fell to 37.03 per dollar on Friday, its worst valuation since the currency was restructured in 1998.

In July, a bitcoin startup named Xapo announced it was raising $20 million, bringing its total backing to $40 million. It was using this funding for an unusually intense security setup. Xapo tells users that they can feel secure because their bitcoin will be stored in offline servers, scattered across multiple continents, in secret underground vaults, with armed guards, and biometric sensors.

Some bitcoin enthusiasts have used their cryptocurrency to travel around the world. Others have spent it on a trip to space. But the very earliest user of bitcoin (after its inventor Satoshi Nakamoto himself) has now spent his crypto coins on the most ambitious mission yet: to visit the future.

EBay Inc. (EBAY)’s Braintree unit, one of its electronic-payments businesses, is exploring ways to support bitcoin payments, a person with knowledge of the discussions said. Braintree, which works with online and mobile-only startups so that people can easily pay for goods and services, has held discussions with bitcoin payment-service provider Coinbase Inc., said the person, who asked not to be identified because talks are ongoing and an agreement hasn’t been signed.

You might soon be able to pay for that Uber ride or that AirBnB reservation using bitcoin. The Wall Street Journal reports that eBay has been working ...

Who cares about Satoshi Nakamoto? Someone else has made Bitcoin what it is and has the most power over its destiny.
