Experts reveal game-changing ways cryptocurrency can boost local economies — do the perks outweigh the cost?
As more people become aware of the negative environmental impacts of advancements in technology, certain industries and businesses are looking to pivot and remake their images in the name of the green transition.
In the cryptocurrency world, Ethereum in 2022 changed its modus operandi from proof of work to proof of stake — and reduced its energy consumption in doing so by nearly 100%. This switch was projected to reduce the company’s pollution from 11 million tons of carbon each year to 870 tons, and it doubled its value to $600 billion.
Bitcoin adherents are touting its ability to contribute to a cleaner future, too. Daniel Batten, an analyst and climate investor, has said that mining operations can help renewable energy farms become immediately profitable and drive continued investment in that industry.
Bitcoin, though, still generates an estimated 95 million tons of carbon dioxide equivalent annually, per the University of Cambridge’s Bitcoin Electricity Consumption Index. That’s a figure some insiders, such as Batten, say is out of step with the latest percentages of renewable energy, which a Bloomberg analyst has put at over 50%, and indeed the Cambridge index says “the estimates currently displayed on our website are grounded on electricity mix data available as of January 2022.” A lot has changed in the nearly three years since, with many professional mining operations going off the grid with renewable energy to improve their long-term return on investment.
These blockchain-based marketplaces provide examples of where the technology has been, how it has changed, and where it’s going. Other breakthroughs could help crypto contribute to sustainability, as CCN reported.
“Skeptics question whether the environmental benefits of blockchain outweigh its energy costs,” Lorena Nessi wrote. “Some argue that while blockchain offers tools for climate solutions, the emissions from mining and other processes may offset these gains.”
The reason many people are so high on the technology is because it offers an efficient, decentralized alternative to traditional methods.
Take, for example, how blockchain has transformed a couple of cities as they relate to the energy industry, as CCN relayed. In New York and Western Australia, homeowners can generate, buy, sell, and trade solar energy. Blockchain technology allows for transparent transactions, enabling the creation of a free market, encouraging the use of renewable energy, and ensuring energy independence while supporting the local economy.
Other developments facilitated by blockchain include the granting of tokens for sustainable behaviors, such as recycling or reducing energy use. The “tamper-proof system” also means ledgers can be created to monitor the environment and verify climate data as well as manage carbon credits, which could revolutionize the questionable nature of such programs.

But CCN noted that integrating artificial intelligence — another energy-sapping technology — and overly relying on such tools, which lack regulation, are great risks.
The wealthy companies that use blockchain, AI, and other inventions that stress the electrical grid have the power to make this change a reality. Otherwise, it will remain up to the public to try to hold them and their executives accountable.

FBI arrests 3 US citizens for plotting to fund ISIS with cryptocurrency
Three US citizens are in federal custody after the FBI arrested them on charges of conspiring to provide material support to ISIS, the designated foreign terrorist organization. The suspects allegedly attempted to use cryptocurrency to purchase weapons, including RPGs and drones, intended for attacks on US servicemembers overseas.
The arrests, carried out on June 5 and 6, mark another instance of law enforcement intercepting crypto-funded terrorism plots before they can materialize. The trio collectively transferred over $2,000 to an individual they believed was affiliated with ISIS, though they were stopped before any weapons purchases went through.
Who was arrested and what they’re accused of
The three defendants are Bisaam Ghafoor, 21, from Leawood, Kansas; Elias Shamsaldeen, 21, from Porterville, California; and Bereen Dzayee, 25, from Lakeside, California. All three face federal charges in the District of Kansas for conspiring to provide material support to terrorism.
According to the Department of Justice complaint, the suspects did more than just move money. They allegedly discussed violent attacks, pledged allegiance to ISIS, and actively sought to acquire military-grade hardware using digital assets. The weapons wish list reportedly included rocket-propelled grenades and drones, with the intended targets being US military personnel stationed abroad.
Acting Attorney General Todd Blanche framed the arrests as evidence of the government’s ongoing commitment to dismantling terrorist networks.
Crypto and terrorism financing: a persistent tension
No specific cryptocurrencies, tokens, or exchanges were identified in connection with the case. In previous terrorism financing cases involving crypto, prosecutors have sometimes named the platforms used, leading to increased regulatory scrutiny on those services.
The modest dollar amount involved, just over $2,000 split among three people, also distinguishes this case from larger-scale terrorism financing operations. The US Treasury’s Office of Terrorism and Financial Intelligence has previously targeted networks moving hundreds of thousands or even millions of dollars in crypto to militant groups.
What this means for crypto investors
The direct market impact of this particular case is effectively zero. The amount of money involved was negligible by any market standard, no specific tokens or platforms were implicated, and the plot was disrupted before it could produce any operational outcome.

Bitcoin’s Stumble Looks Graceful Next to Zcash’s Faceplant — Week in Review
Bitcoin capitulated below its 200-week moving average with a big red candle, trading at $62,495 as of Friday morning. Ethereum saw similar blood, and the altcoin sector in general collapsed further, even the outliers that were shining in previous weeks.
Meanwhile, the stock market continued its parabolic ascent, with the S&P 500, Nasdaq, and Dow Jones all hitting new record levels yet again.
Traditional markets look unstoppable. The S&P 500 is on track for its longest weekly winning streak since 1985. But under the hood, folks like Jim Bianco worry that the entire rally is a one-trick pony. The concentration of money in AI is at historic highs. Space is hot too, led by the imminent SpaceX IPO, with fuel added to the fire by the likes of Fidelity. Even if the current software-focused AI trade cools off, the current trade could pivot heavily towards physical AI – robotics.
There are economic rumblings of discontent. Bernie Sanders has introduced the “American AI Sovereign Wealth Fund Act,” proposing to confiscate 50% of the equity in leading AI companies. The K-shaped economy is intensifying, with small businesses entirely left out of the recent uptick in hiring, marking the worst job outlook since May 2020. Pimco’s chief investment officer has warned that the first sustained credit default cycle in years has begun.
Against this backdrop, crypto is suffering a severe crisis of faith, tipped over the edge by the one-two punch of Saylor selling Bitcoin and the announcement that Zcash had a 4 year double-spend exploit. Here’s a good overview to understand the Zcash bug. In a bitter twist of fate, Taiki Maeda announced he had rotated heavily into Zcash (ZEC) because Saylor fumbled his thesis.
Sentiment was already low, but this bug and the subsequent ongoing price waterfalls is sending it lower, exacerbated by the divergence with equities. While the Nasdaq 100 hits fresh records fueled by AI, Bitcoin and crypto are cratering.
The on-chain data is ugly. Cycle-top buyers who held through the drawdown are finally capitulating, with Glassnode reporting that aggregated realized losses have spiked to $1.3B/day. Long-term bulls are openly stating they aren’t sure Bitcoin recovers this time, or lamenting the opportunity cost of holding Bitcoin while the AI trade minted millionaires. The problems aren’t just price action; fundamental concerns are mounting, as outlined in a viral thread detailing Bitcoin’s current structural issues. Crypto tourists like Brent Johnson are contemplating scenarios where MicroStrategy (MSTR) drops to single-digit support levels.
There are glimmers of hope. DonAlt, the legendary duck, says he will buy “properly” if the weekly candle closes above $71K. That seems all but impossible now, but not in the next couple of weeks. Saifedean Ammous argues that the ultimate backstop remains intact: the narrative that nation-states will buy Bitcoin precisely because it is an asset that cannot be seized by foreign adversaries. The ZEC failure, and a failure all privacy coins suffer currently, strengthens Bitcoin’s primacy as the de facto digital asset store of value.
The altcoin market is faring worse, of course. Delphi Digital declared what we already knew: airdrops don’t work and only create sellers. Builders are exhausted. Algod took to X to voice his frustration with the Bittensor ecosystem, citing unclear conviction and iteration fatigue, while noting that he still holds nearly an ATH amount of TAO but feels his conviction is being seriously tested by a lack of builder incentives.
The old guard of projects are soldiering on. Ryan Sean Adams continues to argue that Ethereum’s value capture mechanism is its use as money—a SoV, MoE, or unit of account. Justin Drake released a long post on the Google quantum computing breakthrough that made many feel Ethereum’s got a great game plan vis-à-vis Bitcoin. Meanwhile, Charles Hoskinson had to clarify that he is not leaving Cardano after ADA dropped 94% back to 2020 levels, prompting critics to beg him to just stop talking.
In a perfect summation of the market’s current feeling, Carl The Moon is officially pivoting to a music career.
Despite the gloom, Hunter Horsley is right: there is a quiet changing of the guard underway in crypto.
The brightest spot is Hyperliquid. HYPE broke all-time highs, proving that tokens can actually perform if they don’t have horrendous tokenomics. Its perpetual volume market share versus centralized exchanges hit 7%. The success even caught the attention of tradfi royalty, with ICE’s Jeff Sprecher noting that it’s bigger than NASDAQ with only 11 people.
But not everyone is convinced. Kyle Samani declared that Hyperliquid is just “Binance 2.0” and will fail due to its centralized technical decisions. This triggered Arthur Hayes to challenge Mr. Samani to a $100k charity wager that HYPE outperforms any top-ten crypto.
Despite this belief in HYPE, Mr. Hayes went from proclaiming “$HYPE to $150”, only to completely dump his HYPE position four days later. In other negative HYPE news, the UK’s FCA published a warning designating Hyperliquid as an unauthorized firm.
Meanwhile in CEX land, Binance announced stock trading on its platform, prompting jokes of being a little late to the party. Coinbase made waves by backing Ethena with open market purchases of ENA.
Perhaps the most fascinating infrastructure shift is the maturity of prediction markets. They’re no longer just for degenerate gambling; they are being actively used for hedging. Rob Hadick notes the sheer volume of teams building sophisticated institutional tooling to place hedging contracts. In a great real-world application, an NYC bar used Kalshi to hedge giving away free drinks if the Knicks win.
Let’s end on some hopium. Chris Perkins pondered whether we might be entering an “alt fundamentals szn” where real product-market fit actually matters. And the hosts of Forward Guidance argued that the massive, concentrated profits currently locked in AI and semis could eventually rotate back to the comparatively starved crypto markets.

From banks to blockchains: US opens new front in Iran sanctions
The US Treasury designated Nobitex alongside Wallex, Bitpin and Ramzinex and sanctioned senior figures connected to Nobitex, including chairman, co-founder and former chief executive Amir Hossein Rad.
According to the Treasury, Nobitex processed more than half of all Iranian digital asset inflows in 2025. Washington also accused it of facilitating transactions linked to the Islamic Revolutionary Guard Corps (IRGC), sanctions evasion, ransomware activity and the Central Bank of Iran’s access to hundreds of millions of dollars in stablecoins.
The sanctions therefore struck at part of the infrastructure that has allowed Iranian individuals, companies and state-linked actors to access international digital asset markets despite years of financial restrictions.
Crypto vs sanctions
Iran’s interest in cryptocurrency is not difficult to explain. Sanctions have sharply limited access to international banking networks, dollar transactions, trade finance and oil revenues. Digital assets do not eliminate these constraints but can provide alternative channels for moving value across borders.
Cryptocurrencies and stablecoins can help facilitate transactions, preserve value and maintain access to foreign markets. Stablecoins are particularly attractive because they reduce exposure to price volatility while still operating outside traditional correspondent banking networks.
Crypto mining has also become part of Iran’s sanctions-evasion toolkit. By using subsidized electricity to mine Bitcoin, Iran can effectively convert domestic energy resources into a globally transferable digital asset.
The strategy comes with costs. Mining places additional strain on Iran’s electricity grid and has been linked to power shortages and public frustration. Yet for a sanctioned economy, the logic remains compelling: when access to conventional finance is restricted, any mechanism capable of transforming local resources into internationally usable value becomes strategically important.
Hormuz and crypto
Cryptocurrency has also emerged in discussions surrounding the Strait of Hormuz, one of the world’s most important energy chokepoints.
Chainalysis reported recently that Iran intended to demand cryptocurrency payments from oil tankers seeking safe passage through the strait during periods of heightened tension. Whether such plans were fully implemented is less important than what they reveal about the potential role of digital assets in future geopolitical confrontations.
For Tehran, cryptocurrency offers several advantages in such scenarios. Payments can move rapidly across borders, avoid some traditional banking restrictions and reduce exposure to frozen accounts or conventional financial controls.
The prospect of crypto-based payments linked to maritime security demonstrates how digital assets could potentially be used not only to move money quietly but also to generate revenue during periods of geopolitical crisis.
The US Treasury has warned of sanctions risks associated with Iranian demands for transit-related payments through the Strait of Hormuz, including payments made through digital assets, fiat currency, offsets, swaps or other arrangements.
Blockchain evasion limits
Despite its advantages, cryptocurrency is not a magic shield against sanctions.
Blockchain transactions often leave traces that can be analyzed by firms such as Chainalysis and Elliptic or by government financial-intelligence agencies.
Once the United States designates a platform such as Nobitex, international exchanges, liquidity providers and counterparties face increased risks if they continue interacting with Iranian-linked wallets. This pushes activity toward smaller, less liquid and often riskier channels.
The sanctions also highlight another vulnerability. Treasury officials noted that Nobitex suffered a major hack in June 2025, underscoring the risks associated with relying on digital financial infrastructure.
Another area of interest is the role of the IRGC, which under Iran’s previous budget law was tasked with exporting roughly 700,000 barrels of crude oil per day—about half of the country’s exports at the time. The organization is also one of Iran’s largest infrastructure contractors.
While available data do not reveal where imported services originated or who ultimately benefited from them, the overlap illustrates the growing importance of non-traditional financial channels within Iran’s sanctioned economy.
Iran is likely to adapt. Activity may shift toward peer-to-peer trading, decentralized platforms, foreign intermediaries, stablecoin networks or new domestic exchanges. Yet each alternative carries costs, whether through reduced liquidity, greater compliance risks or increased exposure to future sanctions.
For Washington, the challenge is sustained enforcement. Sanctioning Nobitex will matter most if it is accompanied by international cooperation, improved blockchain intelligence, pressure on foreign exchanges and clear guidance for shipping firms, insurers and commodity traders.
The United States does not need to stop every Iranian crypto transaction to have an effect. It only needs to make the system more expensive, more traceable, riskier and less attractive for counterparties.
The Nobitex case illustrates how financial warfare has moved from banks to blockchains. Digital assets have given Tehran greater flexibility under sanctions, but they have also created new vulnerabilities.
The more Iran relies on crypto infrastructure, the more that infrastructure becomes part of the sanctions battlefield.
