90% Of All Bitcoins Mined. When Will All Bitcoin Enter CIrculation?
A nonprofit, independent media organization dedicated to telling stories of climate solutions and a just future. As more miners join the network — lured by the skyrocketing value of the bitcoin they receive in exchange for their work — the puzzles get harder, requiring ever greater amounts of processing power, and thus electricity, to solve. Bitcoin mining is now estimated to gobble up more electricity than many entire countries.
The energy used by the Bitcoin network in a single year could power all the tea kettles in the United Kingdom for over three decades. Proponents of Bitcoin would have you believe that many or even most mining operations are in far-flung locations using renewable energy that otherwise would have gone to waste. Jack Dorsey and Elon Musk, whose respective companies Square and Tesla have invested heavily in Bitcoin, claim the cryptocurrency will actually hurry the green energy transition by steering investment into renewables.
A paper prepared by Square predicts that electricity producers and Bitcoin miners will soon become one and the same. Greenidge Generation, a former coal power plant that converted to natural gas and began a Bitcoin mining operation, is positioning itself as part of the clean energy future.

After belching noxious fumes and dumping toxic coal ash into a nearby landfill for seven decades, the plant was poised to be remediated and reused. When Greenidge applied for permits to restart operations, it claimed it would be generating power to meet existing electricity demand.
By , the plant was no longer producing power for the public at all. In an attempt to claw back the tens of millions that Atlas invested to convert the plant to natural gas, Greenidge turned to mining Bitcoin. As Greenidge increased its mining capacity last year, there was a corresponding jump in its contributions to global warming. The equivalent of over , metric tons of carbon dioxide were emitted over the course of last year, a volume comparable to putting nearly 50, new cars on the road.
In late March, the company revealed plans to merge with Support. In its announcement, Greenidge said it wants to more than double its mining capacity on Seneca Lake by July — and to double it again by the end of , at which point it will total 85 megawatts. Greenidge also said that the company plans to replicate its vertically integrated model — cryptocurrency mining at the source of energy production — at other power plants, with a goal of at least megawatts of combined mining capacity by To accomplish that, the company would have to acquire and open at least four other power plants of similar capacity.
Atlas Holdings itself partially owns five power plants in New Hampshire that have more than 1, megawatts of combined capacity. In April, a cryptocurrency mining company called Digihost moved to acquire a megawatt natural gas-fired plant in Niagara County, New York. It could theoretically happen at any aging fossil fuel plant around the country: A source of dirty energy that has outlived its profitability could find a second life as a Bitcoin mining operation.
Although emissions from Bitcoin mining have global consequences, many of the locals opposing Greenidge are equally concerned about its effects on water quality and wildlife. In late March, Phil and Linda Bracht, two of the 30 petitioners on the lawsuit against Torrey, the county planning board, and Greenidge, took me and another petitioner, Carolyn McAllister, out in their boat to get a look at the plant from the water. All three live on Seneca Lake, just a mile from Greenidge.
The first part of the facility to catch the eye is its giant intake pipe, which is 7 feet in diameter and extends further than the length of two football fields from the shore over the water, like an elevated train to nowhere, before dropping below the lake surface.
This is where Greenidge can draw up to million gallons of fresh water per day to cool the plant. Like all thermoelectric power plants, Greenidge uses steam to spin the turbines that produce electricity, but the steam has to be condensed back to water by exchanging heat with the fresh water before it can be reused.
Once-through cooling systems like this — where water is used once and then expelled at a higher temperature — require vast amounts of water, with consequences for both wildlife and water quality. In recent years, fishers have reported fewer and smaller catches on the lake. John Halfman, a professor of geoscience and environmental studies at Hobart and William Smith College on the northern end of Seneca Lake, says the size of the biggest fish caught in the derby has been steadily decreasing, while the time it takes to make a catch is increasing.
Michael Black, a petitioner and fisherman going on his 50th summer living on the lake, said he used to catch between 60 and lake trout each year from his dock south of Greenidge. While there are multiple reasons fish might be suffering, Black worries that hot water discharges are exacerbating the threats they face. Tiffany Garcia, a freshwater ecologist at Oregon State University, wrote a letter to the Town of Torrey raising similar concerns about the effects of hot water discharges on the larger lake ecosystem.
Residents fear that warmer waters will also increase the likelihood and severity of harmful algal blooms, or HABs, near Greenidge. While the presence of blue-green algae or cyanobacteria is normal in lakes, a small number of these organisms produce potent toxins that can be dangerous or even fatal for people and other animals. Under the right conditions — which include lots of sun, still water, and, crucially, heat — these algae can explode in vast, dangerous blooms that are becoming increasingly common in the U.
Gregory Boyer, the director of the Great Lakes Research Consortium at the State University of New York, studied the effect of artificially increasing water temperature by just 2 degrees on Lake Champlain. That small change resulted in a surge of bacteria growth, with toxic species of bacteria increasing to a greater degree than nontoxic species.
In earlier lawsuits challenging permits the DEC issued to Greenidge, Boyer submitted affidavits on behalf of local environmental groups saying that the large discharges of heated water from Greenidge could increase HABs in the area and should be studied further. Gary McIntee, who lives just south of Greenidge, told me that the water flowing down the Outlet is often flush with nutrient-rich runoff from farms as well as discharge from a wastewater treatment plant upstream, creating an ideal mix for HABs.
HABs would render their only source of running water unusable. As the DEC points out , not even boiling, chemical disinfectants, or water filters will protect people from HABs and their associated toxins. HABs can also overwhelm industrial water filtration systems , temporarily rendering public water undrinkable. And as winemaker Vinny Aliperti pointed out, algal blooms keep the tourists away.
Greenidge Generation vigorously denies that its plant is having an adverse impact on the environment. Those drives, however, can be turned off whenever the plant needs maximum water flow. Greenidge also affirmed that it is on schedule to install protective screens by However, although there are specific fishing regulations upstream from the Greenidge discharge canal, the lower part of the Outlet is also a designated trout stream ; this explanation also does not account for the trout that live in Seneca Lake itself.
However, as Boyer told me, the number of HABs was down across the region in , likely because of high winds over the summer. Finally, Greenidge reiterated that its activities are all within the limits set by its permits from the DEC and the U. In March , the plant hired McKeon, a lobbyist at Mercury Public Affairs and the founder and former executive director of Republicans for Cuomo, which organized bipartisan support for the now-governor during his first run for the office.
Environmentalists have repeatedly challenged this decision in court. Instead, the question should be: Is the plant more harmful than no plant at all? For example, since the DEC has recommended new and repowered plants use so-called closed-cycle cooling, in which cooling water is recirculated through the plant instead of discarded, significantly reducing wildlife mortality from impingement and entrainment, as well as the volume of hot water discharges.
Of course, that was before the plant started mining hundreds of thousands of dollars worth of Bitcoin every day. So somebody is greedy. At the end of April, the Town of Torrey gave the company a green light to build four new buildings to house additional Bitcoin-mining hardware. Before leaving town, I spent some time on the Keuka Outlet Trail.
It follows the stream that connects Keuka Lake to Seneca Lake, running over an old railway, and ends near the Greenidge property line, which is posted liberally with no-trespassing signs. The stream used to power an industrial thoroughfare. In there were seven gristmills, 14 sawmills, an oil mill, four carding machines for processing wool and other fibers, as well as multiple distilleries.
A nonprofit has since transformed the area into a nature retreat with a wide gravel path for walking, running, and biking, well-situated benches for moments of quiet repose, and water access for fishing or boating. This could have been the fate of an old coal-fired power plant on Seneca Lake, which in its later years produced energy people rarely needed and was too costly to run at a profit. Nearby residents might have breathed easier, and there would have been one less threat to Seneca Lake and the animals and people who depend on it.

This power plant stopped burning fossil fuels. Then Bitcoin came along.
Cryptocurrency mining is incredibly expensive. It requires you to spend thousands in buying expensive GPUs or ASICs , arranging them together, and spending more to buy power supplies and other computer components. However, not all cryptocurrencies require this much hashing power. At its core, mining is all about solving complex mathematical problems.
What is Cryptojacking? – Definition and Explanation
With more than 4, mineable coins and tokens in existence, which, if any, are the most sustainable cryptocurrencies? Are you a Dogecoin fan? This is because there are so many parameters at play. Many much smaller cryptocurrencies, for instance, naturally have a far lower energy footprint because they involve far fewer daily transactions compared to Bitcoin. Scale them up, however, and they may be just as bad, if not worse than the cryptocurrency we currently love to hate. That said, some cryptocurrencies are inherently more energy efficient than Bitcoin. This is primarily because these currencies use ASIC-resistant algorithms that consume significantly more energy than should be expected relative to how much of the cryptocurrency market they represent. A good example of this is RavenCoin which, by one calculation , accounts for 4.
Why China Is Cracking Down on Bitcoin Mining and What It Could Mean for Other Countries
Cryptojacking is a type of cybercrime that involves the unauthorized use of people's devices computers, smartphones, tablets, or even servers by cybercriminals to mine for cryptocurrency. Like many forms of cybercrime, the motive is profit, but unlike other threats, it is designed to stay completely hidden from the victim. Cryptojacking is a threat that embeds itself within a computer or mobile device and then uses its resources to mine cryptocurrency. Cryptocurrency is digital or virtual money, which takes the form of tokens or "coins.
The Cost of Bitcoin Mining Has Never Really Increased
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. Other countries have banned the use of Bitcoin and cryptocurrencies outright with heavy penalties in place for anyone making crypto transactions.
Lifecycle of cryptocurrencies – From creation to trade and destruction
The Australian government has just recognized digital currency as a legal payment method. Since July 1, purchases done using digital currencies such as bitcoin are exempt from the country's Goods and Services Tax to avoid double taxation. As such, traders and investors will not be levied taxes for buying and selling them through legal exchange platforms. Japan, which legitimized bitcoin as a form of payment last April, already expects more than 20, merchants to accept bitcoin payments. Other countries are joining the bandwagon, albeit partially: businesses and some of the public organizations in Switzerland, Norway , and the Netherlands. In a recent study , unique, active users of cryptocurrency wallets are pegged between 2. But what does the acceptance and adoption of digital currencies have to do with online threats? A lot, actually.
Here’s what could happen after Bitcoin runs out of supply
Speculators rush to sell off their kit as Balkan state announces a crypto clampdown to ease electricity crisis. The largest-scale crypto mining is thought to be taking place in the north of the country, where the Serb-majority population refuse to recognise Kosovo as an independent state and have consequently not paid for electricity for more than two decades. There is serious money to be made — and in a time of ready energy supply it was being made. The number of people mining cryptocurrencies in Kosovo is thought to have skyrocketed in recent years.
Top Cryptocurrencies to Mine in 2021
A cryptocurrency , crypto-currency , or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank , to uphold or maintain it. Individual coin ownership records are stored in a digital ledger , which is a computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. In a proof-of-stake model, owners put up their tokens as collateral. In return, they get authority over the token in proportion to the amount they stake. Generally, these token stakers get additional ownership in the token over time via network fees, newly minted tokens or other such reward mechanisms. Cryptocurrency does not exist in physical form like paper money and is typically not issued by a central authority.
