Bitcoin consumes more electricity every year than the whole of Argentina, analysis by the University of Cambridge suggests.
“Mining” cryptocurrency requires a lot of energy and involves heavy computer calculations to verify transactions.
Cambridge researchers say it consumes around 121.36 terawatt hours (TWh) a year – and is unlikely to fall unless the value of the currency collapses.
This week the value of the currency hit a record $48,000 (£34,820). following Tesla’s announcement that it had purchased approximately $1.5 billion worth of bitcoin and planned to accept it as payment in the future.
But the price increase gives even more incentives to Bitcoin miners to run more and more machines.
And as prices rise, so does energy consumption, according to Michel Rauchs, a researcher at the Cambridge Center for Alternative Finance, who co-created the online tool that generates these estimates.
“It’s just by nature that Bitcoin consumes so much electricity,” Rauchs told the BBC’s Tech Tent podcast. “This is not something that will change in the future unless the price of Bitcoin drops significantly.”
The online tool ranked Bitcoin’s electricity consumption above Argentina (121 TWh), the Netherlands (108.8 TWh) and the United Arab Emirates (113.20 TWh) – and is gradually surpassing that of Norway (122, 20 TWh).
The energy used could power all the kettles used in the UK for 27 years.
However, it also suggests that the amount of electricity consumed each year by always-on but idle home devices in the United States alone could power the entire Bitcoin network for a year.
Bitcoin mining
To “mine” Bitcoin, computers, often specialized, are connected to the cryptocurrency network.
They are tasked with verifying transactions made by people who send or receive Bitcoin.
This process involves solving puzzles that, while not integral to verifying currency movements, provide an obstacle to ensuring that no one fraudulently changes the global ledger of all transactions.
As a reward, miners occasionally receive small amounts of Bitcoin in what is often compared to a lottery.

To increase profits, people often connect large numbers of miners to the network, even entire warehouses full of miners.
This consumes a lot of electricity because the computers work more or less constantly to complete the puzzles.
The University of Cambridge tool models the economic lives of the world’s Bitcoin miners and assumes that all Bitcoin mining machines around the world operate at various efficiencies.
Using the average price of electricity per kilowatt hour ($0.05) and the energy demand of the Bitcoin network, it is then possible to estimate the amount of electricity consumed at any given time.
Environmental conundrum
“Bitcoin is literally anti-efficient,” explained David Gerard, author of Attack of the 50 Foot Blockchain. “So more efficient mining hardware won’t help – it will just compete with other efficient mining hardware.
“This means that Bitcoin’s energy consumption, and therefore its CO2 production, only spirals outward.
“It’s very bad that all this energy is literally wasted on a lottery.”
The price of Bitcoin rose rapidly on Monday after Tesla announced its investment.
But commentators say the investment clashes with the electric car company’s previous environmental stance.
“Elon Musk has thrown away a lot of the good work Tesla has done in promoting the energy transition,” Gerard said. “It’s very bad… I don’t know how he can come back effectively.
“Tesla received $1.5 billion in environmental subsidies in 2020, funded by taxpayers.
“They turned around and spent $1.5 billion on Bitcoin, which is mined primarily with electricity from coal. Their subsidy needs to be looked at.”
A carbon tax on cryptocurrencies could be introduced to offset some of the negative consumption, Gerard suggested.

Trump Courts Crypto Industry Votes, Campaign Donations

July 27, 2024
Donald Trump said at one of the biggest cryptocurrency events of the year that if he is re-elected president, he will fire the chairman of the U.S. Securities and Exchange Commission (SEC) on his first day.
On Saturday, Trump was the keynote speaker at Bitcoin 2024, a gathering of industry heavyweights in Nashville, Tennessee.
The Republican presidential candidate used the event to woo voters and encourage the tech community to donate to his campaign.
Cryptocurrencies have emerged as a political battleground for Republicans, with Trump saying that the Democratic Party and Vice President Kamala Harris were “against cryptocurrencies.”
The crowd was at its most animated when Trump declared, “On day one, I will fire Gary Gensler,” the SEC chairman appointed by now-President Joe Biden. The crowd applauded loudly and began chanting “Trump” at this statement.
SEC files charges against ‘Cryptocurrency King’ Sam Bankman-Frittosentenced to 25 years for stealing billions of dollars from customers of his cryptocurrency exchange FTX.
Speaking for about 45 minutes, Trump outlined some of his ideas for the industry if he wins the November election. He said he would make the United States the crypto capital of the world. His support for the sector is a 180-degree reversal from his comments in 2021, when he told Fox Business he saw Bitcoin as a “scam” that influence the value of the US dollar.
Trump told the crowd at the event that he would retain 100% of the Bitcoin currently owned or acquired by the U.S. government, adding that it would be a “national stockpile of Bitcoin.”
The former president also said he would “immediately appoint a presidential advisory council on Bitcoin and cryptocurrencies.”
He talked about the power needed to mine cryptocurrencies. “It takes a lot of electricity,” he said, adding that he would build power plants “to do that” and that it would “use fossil fuels.”
In recent months, some tech leaders have seen growing support for Trump’s presidential campaign. Tesla founder Elon Musk, who is the world’s richest person, has backed Trump. And cryptocurrency moguls the Winklevoss twins, who attended his speech on Saturday, have also come out in support.
Trump noted that his campaign accepts cryptocurrency donations, saying that in the two months since allowing cryptocurrency transactions, he has received $25 million (£20 million) in donations. However, he did not say how much of the payments came from cryptocurrency.
Trump used his speech to frame cryptocurrency regulation as a partisan issue, saying the Biden administration was “anti-crypto.”
Several Republican lawmakers also attended Trump’s speech, including Senators Tim Scott and Tommy Tuberville. Former Republican presidential candidate and Trump ally Vivek Ramaswamy was also in attendance.
The event was also attended by independent presidential candidate Robert F Kennedy Jr. and Democratic Party congressmen Wiley Nickel and Ro Khanna.
Earlier, during Bitcoin 2024, Democratic Congressman Nickel said that Kamala Harris was taking a “forward-thinking approach to digital assets and blockchain technology.”

WazirX Crypto Exchange Hack and Its Bounty Program: What Does It Mean for Crypto Investors in India?
On July 18, India Cryptocurrency exchange WazirX has been hit by a cyber attack which resulted in the loss of over $230 million worth of digital assets from one of its wallets. The exchange responded by suspending regular trading and reporting the incident to Indian authorities and other cryptocurrency exchanges. The company also launched two reward programs for ethical hackers who can help the exchange trace, freeze, and recover stolen funds.
WazirX said there was a cyberattack on a multi-signature wallet operated through a digital asset custodian service known as Liminal. Multi-signature wallets have a built-in security feature that requires multiple parties to sign transactions.
“The impact of the cyberattack is over $230 million on our clients’ digital assets,” WazirX said in a blog post, adding that INR funds were not affected. The company has firmly denied that WazirX itself was hacked and has brushed aside rumors that it was tricked by a phishing attack.
The exchange also noted that it was “certain” that its hardware keys had not been compromised, adding that an external forensic team would be tasked with investigating the matter further.
But Liminal, after completing its investigation, said: “It is clear that the genesis of this hack stems from three devices compromised by WazirX.”
Meanwhile, WazirX founder and CEO Nischal Shetty said that the attack would have been possible only if there were four points of failure in the digital signature process.
Who is behind the cyber attack?
WazirX has not yet disclosed the suspected parties or perpetrators responsible for the hack. However, news reports have emerged that North Korean hackers were responsible for the incident.
On-chain analytics and other information indicate “that this attack was perpetrated by hackers affiliated with North Korea,” blockchain analytics platform Elliptic said.
In response to The Hindu’s questions to WazirX about the North Korean hackers, cryptocurrency exchange WazirX directed us to its blog and said it was working with law enforcement to investigate whether a known malicious group was behind the attack.
“This incident affected the Ethereum multisig wallet, which consists of ETH and ERC20 tokens. Other blockchain funds are not affected,” WazirX said in its official blog, specifying that approximately 45% (according to preliminary work) of cryptocurrencies were affected by the attack.
The company largely placed the blame on the process of securing Ethereum multisig wallets and said that the vulnerability was not unique to WazirX.
How important is WazirX in the cryptocurrency industry?
WazirX calls itself India’s largest cryptocurrency exchange by volume. As of June 10, it reported total holdings of ₹4,203.88 Crores, or 503.64 million USDT. Tether [USDT] It is a stablecoin, that is, a cryptocurrency pegged to the value of the US dollar, but it is not an official currency of the United States.
When The Hindu tried to access WazirX Public and Real-Time Reserve Proof After the hack, we were greeted with a notice that the page was under maintenance.
WazirX has received both positive and negative reviews in India. The Enforcement Directorate froze the exchange’s assets in 2022, criticizing its operating procedures and lax Know-Your-Customer (KYC) and Anti-Money Laundering (AML) regulations.
“By encouraging obscurity and adopting lax AML norms, it has actively assisted around 16 accused fintech companies in laundering proceeds of crime using the cryptocurrency route. Accordingly, equivalent movable assets amounting to Rs 64.67 Crore in possession of WazirX have been frozen under the PMLA, 2002,” the ED said in a statement.
What will happen to WazirX assets?
It is unlikely that the stolen WazirX assets will be fully recovered anytime soon. This is due to the very nature of cryptocurrency, where assets can be easily mixed, transferred, converted, and sent to anonymous wallets. The chances of asset recovery are even slimmer if it is confirmed that North Korean hackers are behind the incident.
CEO Shetty said on X on July 22 that “small” portions of the stolen funds had been frozen, but declined to provide further details. He added that the majority of the funds had not been moved from the attacker’s wallet.
In recent years, North Korean hackers have stolen billions of dollars in cryptocurrency, aiming to circumvent various financial and economic sanctions.
WazirX is currently working to resume normal operations and has planned to launch an online survey to decide how to resume trading on the platform.
While the Indian exchange has defended its security practices and highlighted the challenges facing the cryptocurrency industry as a whole, savvy crypto traders will be looking for action plans and accountability, rather than emotional reassurance.
What does your rewards program consist of?
WazirX has announced two bounty programs: one to gain more information about stolen funds, and the other to recover them. Both programs are open to everyone except WazirX employees and their immediate family members.
Under the first program, WaxirX will reward up to $10,000 to anyone who can provide the exchange with information that can help freeze the funds. If the bounty hunter is unable to freeze the funds on their own, they should work with WazirX by providing enough evidence to facilitate the process.
But “if the participant fails to freeze and/or does not cooperate with WazirX to facilitate the freezing of funds, then the participant will not be entitled to any rewards,” the exchange said.
The second program, called White Hat Recovery, is aimed at recovering funds. Participants are offered 10% of the amount recovered as a white hat incentive.
“This reward will be paid only after and subject to the successful receipt of the stolen amount by WazirX. The above rewards will be payable in USDT or in the form of recovered funds at the sole discretion of WazirX,” the exchange noted.
The bounty programs are expected to last for the next three months.

Trump Vows to Make US ‘Crypto Capital of the Planet and Bitcoin Superpower’
Speaking to a crowd of supporters at the Bitcoin 2024 Conference in Nashville, Tennessee, former President and Republican candidate Donald Trump said that if elected, he would make the United States the “crypto capital of the planet and a Bitcoin superpower.”
Trump added that he would “appoint a Presidential Advisory Council on Bitcoin and Cryptocurrencies,” which would have 100 days to “design transparent regulatory guidance that will benefit the entire industry.”
Trump has publicly opposed cryptocurrencies until recently. His latest statements serve as a rallying cry for a tech industry that has long called for more flexible regulatory oversight.
Shortly after taking the stage, Trump spent several minutes naming some of the conference attendees, at one point describing Winklevoss Twins Cameron and Tyler as “male role models with big, beautiful brains.” The former president has continued to speak out against electric car mandates and called for more fossil-fuel burning power plants.
Trump also said he would order the United States to withhold all Bitcoin it currently owns “in the future.” The U.S. government reportedly holds billions of dollars in Bitcoin.
About three years ago, Trump called Bitcoin “a fraud“that is “competing against the dollar.” In February 2024, the former president said that establishing a central bank digital currency would represent a “dangerous threat to freedom.” Yet, in May, Trump declared that he was “good with [crypto]“, adding, “if you’re pro-cryptocurrency you’d better vote for Trump.” That same month, he said he would commute with the Silk Road founder Ross Ulbricht’s Sentencingand his campaign said it would accept cryptocurrency donations.
Recent comments from Trump and independent presidential candidate Robert F. Kennedy Jr. have helped make cryptocurrency regulation a major political issue in the 2024 U.S. presidential election. This comes as the SEC intensifies its scrutiny of the cryptocurrency industry. SEC Chairman Gary Gensler, appointed by President Joe Biden, called the activity “full of fraud, scams, bankruptcies and money laundering.” Trump drew applause at the conference after promising to “fire” Gensler. (U.S. presidents have the power to appoint the heads of many federal commissions, including the SEC.)
With Biden out of the raceVice President Kamala Harris’s campaign advisers have He is said to have contacted to cryptocurrency leaders in an effort to “reset” relations with the industry. Harris’s campaign has not yet said whether her stance on the industry differs from Biden’s.
