问题    There’s a zaniness about bitcoin. The currency 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.
   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. 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.
   So many have bought in because the Internet is very good at stoking the fear of missing out. There’s even a trendy acronym, FOMO, to describe the anxiety inspired by scrolling through the social media accounts of people having more fun than you. Bitcoin fosters a particularly potent brand of FOMO. Bitcoin holders have taken to posting screenshots of their swollen accounts. I know a guy who bought a few hundred dollars’ worth of bitcoin as a sort of joke years ago. Now he’s made enough to buy a nice car.
   All I can say is that the crash is going to be great. Bitcoin is too dependent on speculative mania to be of practical use as a currency. But as a symbol of the misguided dream that one can tap into the global data stream and download riches like a pop song, it’s gold.
Which of the following is NOT true about the features of bitcoin?
选项 A、Lack of centralized authority.
B、Easy and fast payment.
C、Protection of personal identity.
D、Personal control of the market.
