A Closer Look at the Future of Money
A Bitcoin update, worthwhile further reading, and a list of upcoming events focused on payments, commerce, and banking.
Cryptocurrencies are still in their early days. Though a growing number of online and real-world businesses accept bitcoins, writer Russ Juskalian found while reporting “A Weekend in Bitcoin City” that they are not yet accepted widely enough to be a reliable substitute for cash.
Neither are bitcoins reliably functioning as a store of value, a second key function of any currency. Bitcoin has proved volatile recently, dropping from a value of over $1,200 in November 2013 to $310 in December 2014.
That fall-off, along with the fact that Bitcoin is still being used to move only about as much cash as it was a year ago, prompted senior editor Antonio Regalado to nominate the currency as one of the “top technology failures of 2014.” “The idea of Bitcoin remains intriguing,” he writes. “But in practice, it is more like a Ponzi scheme that attracts speculators, and it’s become the payment form of choice among professional cybercriminals.” In November, the U.S. Marshals Service auctioned off 50,000 bitcoins seized from drug dealers, worth about $19 million.
Still, advocates continue to see real value in a peer-to-peer digital currency that’s independent of middlemen and government affiliation—and, lately, in the core computer code that makes Bitcoin what it is: the blockchain.
Free and open, the blockchain is maintained by computers around the world and shares some of the design features that laid the foundation for the success of the World Wide Web and Linux, among other technologies. Increasingly, investors believe that the future of Bitcoin lies in the idea of extending or building on the blockchain to create something called sidechains. Sidechains would build on top of the blockchain code—which currently records every Bitcoin transaction as an open, public ledger—to create systems that secure other kinds of assets beyond payments, such as contracts or ownership of stock.
Gavin Andresen, the driving force behind Bitcoin, foresees a future in which the currency might come to cheaply power a diverse collection of services focused on trust and security.
To use Bitcoin today, you must install a special wallet, like Coinbase, on your computer or mobile phone. You can trade U.S. dollars or other currency for bitcoins at exchanges like Bitstamp. Both of these sites explain how their systems work, and the nonprofit Bitcoin Foundation has published an explanation of the technology behind the payment system.
For insight into how Bitcoin solves some of the special challenges of digital currencies, a good starting place is “Explain Bitcoin Like I’m Five,” an essay published on Medium by financial consultant Nik Custodio.
The End of Money: Counterfeiters, Preachers, Techies, Dreamers—and the Coming Cashless Society
by David Wolman
Da Capo Press, 2012
Wired contributing editor David Wolman exposes the unsavory side of cash as he seeks to measure its place in the modern world, talking to counterfeiters, coin collectors, and everyone in between.

Bitcoin and the Future of Money
by Jose Pagliery
Triumph Books, 2014

The Age of Cryptocurrency
by Paul Vigna and Michael J. Casey
St. Martin’s Press, 2015
A pair of Wall Street Journal writers team up to produce a sympathetic overview of cryptocurrencies. The book ends with the prediction that encryption-based, decentralized digital currencies “do have a future,” even though it’s a major task to convince people of their benefits. Those benefits include potentially making the financial system far more efficient and offering an affordable alternative to the many people without access to banks today.
