Because some bitcoin investors have become millionaires overnight, more and more people are intrigued by the possibility of striking it rich through investing in cryptocurrencies like Bitcoin. A cryptocurrency is a virtual medium of exchange that exists only electronically; it has no physical counterpart such as a coin or dollar bill, and no money has been staked to start it. Cryptocurrencies are decentralized, meaning that there is no central authority like a bank or government to regulate them. The advantage of this is that there are no transaction fees, anyone can use it, and it makes transactions like sending money across national borders simpler.

Police find bitcoin mine using stolen electricity in West Midlands
Summer on Seneca Lake, the largest of the Finger Lakes in upstate New York, is usually a time of boating, fishing, swimming and wine tasting. But for many residents of this bucolic region, there's a new activity this season — protesting a gas-fired power plant that they say is polluting the air and heating the lake. They have increased the electrical power output at the gas-fired plant in the past year and a half and use much of the fossil-fuel energy not to keep the lights on in surrounding towns but for the energy-intensive "mining" of bitcoins.
Bitcoin is a cryptocurrency — a digital form of money with no actual bills or coins. The computers earn small rewards of bitcoin by verifying transactions in the currency that occur on the internet around the world. The math required to verify the transactions and earn bitcoins gets more complex all the time and demands more and more computer power. An estimate from the University of Cambridge says global bitcoin miners use more energy in a year than Chile.
When the energy comes from fossil fuels, the process can add significantly to carbon emissions. The Greenidge plant houses at least 8, computers and is looking to install more, meaning it will have to burn even more natural gas to produce more energy. Private equity firms like Atlas buy companies, often using debt, and hope to sell them later at a profit.
They are secretive operations with investments that can be hard to track. As investor criticism prompts some public companies to dump fossil fuel assets, private equity firms are ready buyers.
In a report last fall, the Environmental Assessment Office, a provincial agency, said the project failed to comply on 16 of 17 items inspected. As a result, Coastal GasLink was ordered to hire an independent auditor to monitor its work to prevent site runoff that can pollute streams and harm fish. Because private equity firms expect to hold their investments for only a few years, they often keep alive fossil-fuel operations that would otherwise be mothballed, said Tyson Slocum, director of the energy program at Public Citizen, a nonprofit consumer advocacy group.
In , for instance, the private equity firm ArcLight Capital Partners of Boston bought into Limetree Bay, an oil refinery and storage facility in St. Croix in the U. Virgin Islands. The operation had gone bankrupt after a series of toxic spills, but it reopened in February.
Just three months later, it was shuttered after it unleashed petroleum rain on nearby neighborhoods. A spokeswoman for ArcLight said the firm "takes its responsibilities to protect the environment and support local communities seriously and will continue to strive to meet the highest standards. Because private equity firms are secretive, their investors may not know what they own or the risks, said Alyssa Giachino of the Private Equity Stakeholder Project, a nonprofit organization that examines the industry's impact on communities.
She said pension funds and their beneficiaries may end up with more fossil fuel exposure than they realize and may not have a full appreciation of the risks. They include heavy impacts on communities of color, risks of litigation and environmental penalties and long-term climate effects, she said.
KKR is a huge energy investor on behalf of endowments, public pensions and other institutional investors. Like many of its private equity brethren, KKR has deployed far more money in conventional energy assets like the Coastal GasLink Pipeline than in renewables.
KKR didn't dispute those figures in emails. KKR's spokeswoman said the firm is "committed to investing in a stable energy transition, one that supports a shift to a clean energy future while recognizing the ongoing importance of supplying the conventional energy needed for well-being and economic growth around the world today. KKR recently added a team focused on energy transition investments in North America. Private equity investors sometimes "leave behind messes for someone else to clean up," said Clark Williams-Derry, energy analyst at the Institute for Energy Economics and Financial Analysis.
The lakeshore facility is operating within its federal and state environmental permits, he said, and it has created 31 jobs, a company-commissioned report shows. Williams-Derry said cryptocurrency's potential profits add to the appeal of buying low-cost and carbon-intensive power plants. While natural gas-fired plants like Greenidge's in New York aren't as problematic as those that use coal, they still generate damaging greenhouse gases, he said.
Kirt said that after Greenidge took over the plant, it sought ways to earn higher returns on its surplus energy. It struck gold with bitcoin mining. During the 12 months that ended Feb. Greenidge's owner, the private equity firm Atlas, is on a roll. Atlas bought the acre coal-fired Greenidge plant in , three years after it had closed.
Converted to natural gas, the almost year-old plant began operations in , generating energy to the grid only at times of high demand. In , Greenidge began using the plant to power bitcoin mining and increased its output. It still supplies surplus power to the local electrical grid, but a lot of the power it generates is now used for bitcoin mining. And it has plans for expansion at Greenidge and elsewhere, company documents show.
Last week, Greenidge announced a new bitcoin mining operation at a retired printing plant Atlas owns in Spartanburg, South Carolina. In March, Greenidge said its Bitcoin mining capacity of 19 megawatts should reach 45 megawatts by December and may ramp to megawatts by as it replicates its model elsewhere. Larger gas-fired plants in the U. Also in March, Greenidge announced a merger with Support.
The deal, which is expected to close in the third quarter of this year, will give Atlas control of the merged company and access to public investor money. Andrew Bursky, founder of Atlas, owns half to three-quarters of Atlas, a regulatory filing shows. Neither Atlas nor Bursky would comment for this article. Greenidge, which disputes that view, said last month that its operations would soon be carbon neutral.
It is buying credits that offset the plant's emissions from an array of U. Judith Enck, a former regional administrator for the Environmental Protection Agency who is a senior fellow and visiting faculty member at Bennington College in Vermont, has doubts. So far, legal challenges to the Greenidge operation have failed. Materials issued by Greenidge say state environmental authorities have determined that the plant "does not have a significant impact on the environment. Still, emissions from the plant are rocketing.
At the end of last year, even though it was operating at only 13 percent capacity, the plant's carbon dioxide equivalent emissions totaled , tons, up from 28, tons in January, according to regulatory documents Earth Justice received under an open records request. Before it began mining bitcoins, the plant generated carbon emissions of , tons in and 39, tons in , federal documents show.
On June 5, residents staged a protest against the plant at a nearby Department of Environmental Conservation office in Avon. If regulators don't rein in the Greenidge plant, they say, 30 other power plants in New York could be converted to bitcoin mining, imperiling the state's emission-reduction goals. As the greenhouse gas emissions associated with this type of facility may be precedential and have broader implications beyond New York's borders, DEC will consult with the U.
Water usage by Greenidge is another problem, residents said. The current permit allows Greenidge to take in million gallons of water and discharge million gallons daily, at temperatures as high as degrees Fahrenheit in the summer and 86 degrees in winter, documents show. Rising water temperatures can stress fish and promote toxic algae blooms, the EPA says. A full thermal study hasn't been produced and won't be until , but residents protesting the plant say the lake is warmer with Greenidge operating.
Greenidge recently published average discharged water temperatures from March 1 to April 17, during the trout spawning season; they were around 46 degrees to 54 degrees, with differences between inflow and outflow of 5 degrees to 7.
From June 7 to July 6, Greenidge said, water temperatures recorded at a buoy about 10 miles north of the Greenidge plant and at a depty of three-and-a-half feet have averaged The low of 61 degrees occurred on June 7 and the high of 73 was recorded on July 1.
Over longer periods, temperatures have spiked, however. NBC News reviewed a February email from the DEC to a resident stating that since , the plant's daily maximum discharge temperatures have been 98 degrees in the summer and 70 degrees in winter.
The Greenidge spokesperson said, "The limits already protect the lake's fishery and the public health, and they have been clearly validated as not concerning. Not everyone wants Greenidge gone. Gwen Chamberlain, a former local newspaper editor, is one of three members of a community advisory board working with Greenidge to advance the region's economy.
Peter Mantius, a former journalist who writes about environmental politics in the region , said the payments, while greater than zero, are far less than what the plant once generated, thanks to a favorable tax assessment arrangement. Meanwhile, residents like Buddington feel compelled to keep fighting. A former stockbroker, she won the Pulitzer Prize in for her "trenchant and incisive" reporting on Wall Street.

The U.S. government's bitcoin bonanza: How, where and when to sell?
Some imagine it as a chance for a new life, run on entirely different principles from the chaotic Earth. Over time, though, the illusion is shattered as multinational corporations operating under the banner of governments move in, viewing Mars as nothing but an extension to business-as-usual. It is a story that undoubtedly resonates with some members of the Bitcoin community. The vision of a free-floating digital cryptocurrency economy, divorced from the politics of colossal banks and aggressive governments, is under threat. Take, for example, the purists at Dark Wallet , accusing the Bitcoin Foundation of selling out to the regulators and the likes of the Winklevoss Twins.
How To Mine Bitcoins
The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity. Despite a billion-fold increase in hashing activity and a million-fold increase in total energy consumption, we find the cost relative to the volume of transactions has not increased nor decreased since This is consistent with the perspective that, in order to keep the Blockchain system secure from double spending attacks, the proof or work must cost a sizable fraction of the value that can be transferred through the network. Bitcoin is a digital currency launched in by an anonymous inventor or group of inventors under the alias of Satoshi Nakamoto Nakamoto, It is the largest cryptocurrency in market capitalization with over billion dollars Chan et al. As a decentralized currency, Bitcoin differs from government regulated fiat currencies in that there exists no central authority within the network to verify transactions and prevent frauds and attacks Sin and Wang, Instead, Bitcoin relies on a highly replicated public ledger, secured by means of a hash chain and validated through community consensus Akcora et al. All users can announce a new transaction but such a transaction will be considered valid and included in the ledger only once it is verified by a majority of the network nodes.
Bitcoin ban: These are the countries where crypto is restricted or illegal
There's also live online events, interactive content, certification prep materials, and more. Mining is the process by which new bitcoin is added to the money supply. Mining also serves to secure the bitcoin system against fraudulent transactions or transactions spending the same amount of bitcoin more than once, known as a double-spend. Miners provide processing power to the bitcoin network in exchange for the opportunity to be rewarded bitcoin. Miners validate new transactions and record them on the global ledger.

The recent rally in the digital asset has come on the back of interest from big global financial institutions such as BlackRock and Goldman Sachs. According to experts, extreme volatility is a part and parcel of cryptocurrency trading and one must be prepared for losses that could include wiping out of one's investments in this asset class.

Bitcoin and other prominent cryptocurrencies have gained much attention since the last several years. Globally known as digital coin and virtual currency, this cryptocurrency is gained and traded within the blockchain system. The blockchain technology adopted in using the cryptocurrency has raised the eyebrows within the banking sector, government, stakeholders and individual investors.
By Emily Flitter. And it could get much bigger. The bitcoins had belonged to Silk Road, an anonymous online black market that authorities say was a conduit for purchases of drugs and computer hacking services - even a place where assassins may have advertised. It was shuttered after an FBI raid in September, when agents took control of its server and arrested the man they say was its founder in San Francisco.
Bitcoin has been controversial since its beginning in , as have the subsequent cryptocurrencies that followed in its wake. While widely criticised for its volatility, its use in nefarious transactions and for the exorbitant use of electricity to mine it, Bitcoin is being seen by some, particularly in the developing world, as a safe harbour during economic storms. But as more people turn to cryptos as either an investment or a lifeline, these issues have manifested in an array of restrictions on their usage. The legal status of Bitcoin and other altcoins alternative coins to Bitcoin varies substantially from country to country, while in some, the relationship remains to be properly defined or is constantly changing. Some countries have placed limitations on the way Bitcoin can be used, with banks banning its customers from making cryptocurrency transactions.
The island nation is the first to use more electricity on mining cryptocurriencies than on its households — thanks in part to its magma-fuelled power plants. That is more than households use in the nation of , people, according to the national energy authority. Mining is the name for the decentralised process that underpins the integrity of most cryptocurrencies.
