Five of us from TwoSixNine put together a briefcase that takes pocket change on one end, and prints out Bitcoin private keys on the other. We thought it was a pretty cool hack, so we brought it to DEF CON because we thought people might like it.
And like it they did: and this is awesome. We weren t expecting the incredibly positive reception to our hack, but we re glad you dig it. Thank You. We were also not expecting the number of people who assumed we were planning to produce and sell these as a product. How much? , When will they be available? , and Can you make one for my hackerspace and/or Bitcoin meetup? were common questions that we were not ready for.
And then the recommendations for improvements came in. Battery power, bill acceptors, magnetic stripe and NFC readers, webcams, touch screens, and SMS transactions were suggested.
So, we re going to try it. The plan is to clean up and open source our code and make free instructions available so you can build one yourself. We willRecently, a friend came up to me and asked Raghu, how do I obtain bitcoins? I stared at him with an empty, blank look. Despite all the recent talks about bitcoins and their growing popularity, even with the Reserve Bank of India (RBI) getting involved, I realised that I knew absolutely nothing about the bitcoin except the fact that it was associated with the Silk Road - an illegal online black market that used bitcoins as its defacto virtual currency to enable regular folks to obtain all sorts of illegal items easily and anonymously.

Inspired by and technically nearly identical to Bitcoin (BTC), Litecoin creation and transfer is based on an open source protocol and is not managed by any central authority.
After Bitcoin, Litecoin is the second-largest true cryptocurrency by market capitalization. Litecoin was released via an open-source client on GitHub on October 7, 2011 by Charles Lee, a former Google employee. It was a fork of the Bitcoin-Qt client, differing primarily by having a decreased block generation time, increased maximum number of coins, different hashing algorithm (scrypt, instead of SHA-256), and a slightly modified GUI. During the month of November 2013, the aggregate value of Litecoin experienced massive growth which included a 100% leap within 24 hours. Litecoin reached a $1 billion marketcap in November 2013 but as of February 2015, its market capitalization is back to pre-NovemberList of Companies, Stores, Shops 1 year ago by Jonas Chokun 20 Who Accepts Bitcoins?
