One of them is worth over $11,000 and some experts say it could rise further. Bitcoin, the world’s most popular virtual currency, allows people to buy goods and services and exchange money without involving banks, credit card issuers or other third parties.
It has a fuzzy history, having been used by hackers to demand ransom and for the purchase of illegal drugs online. But recently it’s become more popular with a different crowd: speculative investors.
As its price keeps rising, here’s a brief look at bitcoin.
HOW BITCOINS WORK
Bitcoin is a digital currency that is not tied to a bank or government and allows users to spend money anonymously. The coins are created by users who “mine” them by lending computing power to verify other users’ transactions. They receive bitcoins in exchange. The coins also can be bought and sold on exchanges with US dollars and other currencies.
HOW MUCH IS IT WORTH?
One bitcoin trades for $11,290, according to coindesk, a website that monitors the price. That’s a more than ten-fold increase from the start of the year, when it was worth under $1,000.
The value of bitcoins can swing sharply, though. A bitcoin’s value plunged by 22 percent against the dollar in just three days earlier this month.
WHY BITCOINS ARE POPULAR
Bitcoins are basically lines of computer code that are digitally signed each time they travel from one owner to the next. Transactions can be made anonymously, making the currency popular with libertarians as well as tech enthusiasts, speculators — and criminals.
IS IT REALLY ANONYMOUS?
Yes, to a point. Transactions and accounts can be traced, but the account owners aren’t necessarily known. However, investigators might be able to track down the owners when bitcoins are converted to regular currency.
WHO’S USING BITCOIN?
Some businesses have jumped on the bitcoin bandwagon amid a flurry of media coverage. Overstock.com accepts payments in bitcoin, for example. The U.S. exchange operator CME Group said in October that it plans to open a futures market for the currency before the end of the year, if it can get approval from regulators. Still, its popularity is low compared with cash and cards, and many individuals and businesses won’t accept bitcoins for payments.
Some high-profile banking executives have spoken against bitcoin, with JPMorgan Chase CEO Jamie Dimon calling it a “fraud.”
HOW BITCOINS ARE KEPT SECURE
The bitcoin network works by harnessing individuals’ greed for the collective good. A network of tech-savvy users called miners keep the system honest by pouring their computing power into a blockchain, a global running tally of every bitcoin transaction. The blockchain prevents rogues from spending the same bitcoin twice, and the miners are rewarded for their efforts by being gifted with the occasional bitcoin. As long as miners keep the blockchain secure, counterfeiting shouldn’t be an issue.
HOW BITCOIN CAME TO BE
It’s a mystery. Bitcoin was launched in 2009 by a person or group of people operating under the name Satoshi Nakamoto. Bitcoin was then adopted by a small clutch of enthusiasts. Nakamoto dropped off the map as bitcoin began to attract widespread attention. But proponents say that doesn’t matter: The currency obeys its own internal logic.
An Australian entrepreneur last year stepped forward and claimed to be the founder of bitcoin, only to say days later that he did not “have the courage” to publish proof that he is.
