I was interviewed and quoted a few times in the past couple weeks:

Is Bitcoin Stalling? at Technology Review:

The design of Bitcoin and the blockchain, its public transaction ledger, make it challenging to distinguish specific types of transactions. Nonetheless, researchers from the U.S. Federal Reserve determined in a recent analysis that the currency is “still barely used for payments for goods and services.” Last week, nearly 200,000 bitcoins changed hands each day, on average. But fewer than 5,000 bitcoins per day (worth roughly $1.2 million) are being used for retail transactions, according to estimates by Tim Swanson, head of business development at Melotic, a Hong Kong-based cryptocurrency technology company. After some growth in 2013, retail volume in 2014 was mostly flat, says Swanson.

After the Bitcoin Gold Rush at The New Republic:

“Some of the New York Bitcoin Center guys are pretty religious,” says Tim Swanson, who has written two e-books on cryptocurrencies in the past year, most recently The Anatomy of a Money-like Informational Commodity: A Study of Bitcoin. Before that, while living in China, he built his own graphics-chip miners. (Some of his miners have since been re-purposed as gaming systems.) Swanson has grown increasingly skeptical that Bitcoin will unsettle the existing finance megaliths. “You have centralization without the benefits of centralization,” he says. Bitcoin’s promise of frictionless finance is drowning in the ever more immense cost of mining, user-friendly infrastructure, and appeasing regulators.

“Being your own bank sounds cool in theory,” Swanson says, “but it’s a pain in reality.”

Beyond Bitcoin, episode #27: An Architecture For The Internet Of Money at Let’s Talk Bitcoin.

In this episode, Meher Roy does a fantastic job explaining what a neutral, agnostic protocol actually is and why the current allotment of cryptocurrency “protocols” are not real protocols.  Many thanks to Arthur Falls for his time, patience and great questions.  We will all miss the show.
