Still, there’s a zaniness about the currency. Bitcoin is built on a weird mix of the most old-fashioned kind of speculative greed, bolstered by a contemporary utopian cyberlibertarian ideology. Boosters say that bitcoin is the currency of the future. I’d argue that the phenomenon is a digital gold rush perfectly emblematic of the present.

Some of bitcoin’s appeal comes from the fact that it does not physically exist. Each bitcoin is just a string of numbers. Instead of a bank, a decentralized network of computers ensures the authenticity of bitcoin and issues new ones by doing complex calculations. This allows bitcoin to be traded peer to peer, bypassing credit card companies and payment processors. It’s digital cash, offering the same relative anonymity and freedom as a paper sack of bills. WikiLeaks began accepting bitcoin donations in 2011 in order to bypass PayPal and credit card companies, which had frozen payments to the organization.

The WikiLeaks episode hints at the utopian promise built into bitcoin by its creator, a mysterious programmer called Satoshi Nakamoto, whose identity is a subject of dispute and intrigue. The ideas behind bitcoin can be traced to a 1988 tract called the Crypto Anarchist Manifesto, which loftily predicted a future where anonymity-protecting technology made state control of the market impossible. Everything would be for sale to anyone all the time, 100 percent tax-free. Many of bitcoin’s hard-core fans see the currency as a revolutionary step toward this anarchocapitalist wonderland.

I’m skeptical. I don’t think we’ll all be paying in bitcoin for tickets to Kanye West’s 2024 presidential victory tour. You can’t use bitcoin for much today besides gambling in online casinos and reserving seats on Virgin Galactic spaceflights, and a vast majority of it is held by speculators. Even with the imprimatur of government regulation, the promise of bitcoin seems to end with helping online retailers avoid credit-card processing fees. Bitcoin is mainly innovative in the way of credit default swaps: new ways to gamble with money.

Bitcoin is most interesting on an emotional level. Its sheen of technomagic has let uber-rational geeks treat the casino-floor frenzy as a serious technological story. Tech blogs breathlessly track the price of bitcoin. Each new business that accepts bitcoin is heralded with the fanfare of a despot opening his country’s borders to a new, previously outlawed luxury. The drumbeat suggests that getting rich is as simple as being an early adopter.
