"Bitcoin mining - the process in which a bitcoin is awarded to a computer that solves a complex series of algorithms - is a deeply energy-intensive process.
"Mining" bitcoin involves solving complex math problems in order to create new bitcoins. Miners are rewarded in bitcoin.
Earlier in bitcoin's relatively short history - the currency was created in 2009 - one could mine bitcoin on an average computer. But the way bitcoin mining has been set up by its creator (or creators - no one really knows for sure who created it) is that there is a finite number of bitcoins that can be mined: 21m. The more bitcoin that is mined, the harder the algorithms that must be solved to get a bitcoin become."
"Bitcoin is stored on software known as a digital wallet that is secured through encryption. A password is used as a decryption key to open the wallet and access the bitcoin. When a password is lost the user cannot open the wallet.
The fraudster had been sentenced to more than two years in jail for covertly installing software on other computers to harness their power to "mine" or produce bitcoin.
When he went behind bars, his bitcoin stash would have been worth a fraction of the current value. The price of bitcoin has surged over the past year, hitting a record high of US$42,000 in January. It was trading at US$37,577 on Friday, according to cryptocurrency and blockchain website Coindesk."
"Why has Bitcoin become so popular? One possible explanation is that exploding interest in Bitcoin over the past several days is being driven by economic uncertainty in Europe. Fearful of an earlier proposed European Union plan to partially fund a Cypriot bailout by imposing new taxes on Cypriots' bank deposits, goes the theory, some Cypriots (and Spaniards, for similar reasons) flocked to Bitcoin to attempt an escape from the clutches of potential taxes."
"No one stepped forward to claim these bitcoins, which were found in electronic "wallets" used to store the digital currency. An additional 144,336 bitcoins, worth more than $128m today, were also discovered, but the government's claim on them is being disputed by Ross William Ulbricht, 29, who US authorities say was the founder and main operator of Silk Road. They had been stashed on his laptop."
"Kristoffer Koch invested 150 kroner ($26.60) in 5,000 bitcoins in 2009, after discovering them during the course of writing a thesis on encryption. He promptly forgot about them until widespread media coverage of the anonymous, decentralised, peer-to-peer digital currency in April 2013 jogged his memory.
Bitcoins are stored in encrypted wallets secured with a private key, something Koch had forgotten."
"The bitcoin blockchain was created, in part, to address this historical weakness. After the 21 millionth bitcoin is mined, in around 2140, the system will produce no more."
"The proto-currency known as RSCoin has vastly greater scope than Bitcoin, used for peer-to-peer transactions by libertarians across the world, and beyond the control of any political authority.
The purpose would be turned upside down. RSCoin would be a tool of state control, allowing the central bank to keep a tight grip on the money supply and respond to crises. It would erode the exorbitant privilege of commercial banks of creating money out of thin air under a fractional reserve financial system."
"We're tempted to file this one under "the more things change, the more they stay the same." A wristband, called Nymi, that taps the user's heartbeat as a biometric marker, will also double as a bitcoin wallet."
"In theory, when the conventional financial system is experiencing turbulence, alternative currencies such as bitcoin should have their time to shine. The decentralised nature of the currency means that it's impossible for any central bank to impose controls on it, while the pseudonymity at its core could make it the perfect vehicle to get money into and out of the country while avoiding legal reprisals."
"El Salvador has become the first country in the world to adopt bitcoin as legal tender after its congress approved President Nayib Bukele's proposal to embrace the cryptocurrency in an effort to promote "financial inclusion", investment and economic development."
""There has been a high degree of improvisation in the rollout of Chivo and a great deal of opacity," says Ricardo Castaneda, a local economist. "The app asks for access to your microphone and your contacts, which are not needed for a wallet. Bitcoin might be a distraction but given the decision to push ahead with the plan despite popular opposition and the advice of experts, it could also be an important pillar of Bukele's political project.""
"Everyone in the cryptocurrency world has heard of Satoshi Nakamoto, the mysterious inventor of Bitcoin. But not many have heard of Peter Bushnell, the not-so-mysterious inventor of Feathercoin. On 20 April, he announced his alternative currency to a gaggle of online followers. One month later, nearly 7m of them have been mined"
"The criminals who took over the library system want $35,000 in Bitcoin to give it back.The criminals who took over the library system want $35,000 in Bitcoin to give it back. The FBI is investigating. The library does not store sensitive patron data, so the hack does not expose patrons to data-breach risks."
"That Crisis Strategy Draft included the line: "At the risk of appearing hyperbolic, this could be the end of Bitcoin, at least for most of the public.""
