Iran announced plans to charge Bitcoin and USDT transit fees for oil tankers passing through the Strait of Hormuz. Within two weeks, scammers impersonated Iranian officials and sent fraudulent messages to stranded vessels, demanding cryptocurrency payments in exchange for safe passage. At least one tanker that paid the fake fee was fired upon by Iranian Revolutionary Guard boats when attempting to cross. Maritime risk firm MARISKS confirmed the scam exploited shipowners’ anxiety amid heightened regional tensions. Chain analysis firms TRM Labs and Chainalysis found no evidence of large-scale crypto payments actually being made to Iranian entities. Legal experts warned that even payments made to scammers—if intended for Iran—could violate international sanctions. The incident highlights how cryptocurrency’s irreversibility, often touted as a strength, becomes a critical risk in conflict-driven fraud. While Iran’s proposal initially sparked excitement in crypto circles, it ultimately created a new attack vector for deception, leaving ships trapped, fined, or even under fire.

Deep Tide Introduction: Less than two weeks after Iran announced it would collect Bitcoin transit fees in the Strait of Hormuz, scammers impersonated Iranian officials and sent fake messages to stranded oil tankers demanding BTC and USDT.

At least one tanker that paid the fake transit fee was fired upon by the Iranian Revolutionary Guard Corps when attempting to pass. Chain analysis firms TRM Labs and Chainalysis both stated that no large-scale on-chain evidence of cryptocurrency payments has been found so far.

Iran announced it would collect transit fees in Bitcoin, and within two weeks, scammers turned this narrative into a weapon.

According to a Reuters report on April 21, the maritime risk management company MARISKS issued a warning: unidentified individuals are posing as Iranian authorities and sending false messages to ships stranded on the western side of the Strait of Hormuz, demanding payment of "transit fees" in BTC or USDT in exchange for safe passage. MARISKS believes that at least one of the vessels fired upon by Iranian Revolutionary Guard Corps speedboats on April 18, when Iran briefly opened the strait, was a victim of this scam.

The absurdity of the incident lies in the entire chain of causality: a sovereign state announces it will collect Bitcoin transit fees, scammers copy this rhetoric to commit fraud, shipowners believe it and pay, and then get shot at by the real Iranian military.

From "National-Level Settlement Tool" to Attack Surface for Scammers

The story begins in early April.

From March 30 to 31, the Iranian parliament passed the "Hormuz Strait Management Plan," formally writing into law the transit fee system that the Islamic Revolutionary Guard Corps had already been implementing since mid-March. According to the Financial Times, Hamid Hosseini, spokesperson for the Iran Oil, Gas, and Petrochemical Products Exporters Union, confirmed that fully loaded tankers are required to pay a fee of $1 per barrel, with payment methods including Bitcoin, USDT, or Chinese yuan. A supertanker carrying 2 million barrels of crude oil could face a single transit fee of up to $2 million.

Upon the news, Bitcoin's price jumped 5%, briefly breaking through $72,700. The crypto community quickly interpreted this as a milestone validation of Bitcoin as a "neutral settlement layer for international trade." Institutions like Bitwise even linked it to predictions of Bitcoin reaching $1 million.

But there were also many skeptics.

Sam Lyman of the Bitcoin Policy Institute pointed out in a report on April 15 that large-scale collection of Bitcoin transit fees with existing technology is "almost impossible." Ari Redbord, global policy head at TRM Labs, told Fortune magazine that on-chain data does not show transit fee payments occurring on a large scale. Chainalysis, in its analysis report, noted that on-chain activities of entities linked to Iran primarily rely on USDT on the Tron network, not Bitcoin.

Scammers don't care about these technical debates. They only need a credible narrative, and the Iranian government has already written the script for them.

Ships That Paid the Fake Fee Got Shot at for Real

According to Reuters and DL News, the wording of the scam messages highly imitates official language. The scammers required shipowners to submit ship documents, claiming they would be assessed by the "Iranian security department." After passing the assessment, payment in BTC or USDT would be required, after which the ship could "safely pass through the strait at the scheduled time."

Approximately 400 ships and about 20,000 crew members are currently stranded in the Persian Gulf. With the U.S. blockading Iranian ports and Iran repeatedly opening and closing the strait for passage, the anxiety of shipowners is understandable. The scammers precisely exploited this anxiety.

On April 18, Iran briefly opened the strait, and some ships attempted to pass. According to the UK Maritime Trade Operations (UKMTO), two Iranian Revolutionary Guard Corps speedboats opened fire on an oil tanker trying to exit the strait, forcing it to turn back. MARISKS believes this tanker had previously paid the cryptocurrency "transit fee" to scammers, thinking it had obtained passage permission.

They paid, but the money didn't go to Iran. The ship was still shot at.

Paying Scammers Could Also Violate Sanctions Laws

Even more ironically, even if shipowners realize they have been scammed, the legal risks won't disappear.

Xue Yin Peh, investigation strategy head at Chainalysis, told Decrypt that regardless of whether the recipient is actually the Iranian authorities, as long as the payer intended to pay a sanctioned regime, it could constitute a violation of OFAC, EU, and UK sanctions regulations. In other words, even if you thought you were paying Iran and the money ended up in a scammer's pocket, regulators could still pursue your "subjective intent."

Isabella Chase, head of policy for Europe, the Middle East, and Africa at TRM Labs, also warned that any wallet addresses associated with such demands should be considered "high-risk," and cryptocurrency payments do not provide any "safe harbor" in terms of sanctions compliance.

This creates a nearly unsolvable dilemma for shipowners: paying Iran violates sanctions, paying scammers might also violate sanctions, and not paying means continuing to drift in the Persian Gulf.

"Bitcoin's Irreversibility" Turns from Advantage to Flaw

The most noteworthy aspect for the crypto industry to reflect on is how Bitcoin's core characteristics performed in this scenario.

Benzinga's report highlighted the key issue: cryptocurrency payments cannot be reversed once sent. Traditional bank transfers at least offer the possibility of freezing and recovery, but once Bitcoin or USDT is transferred, the funds are lost. This feature is called "trustless settlement" in normal commercial contexts but becomes "irrecoverable loss" in the combined scenario of war and fraud.

This might be the most absurd crypto story of 2026... Iran's plan to collect transit fees in Bitcoin may never have been truly implemented, but scammers have already made money from this story, and an oil tanker got shot because of it.

ZEC Co-Founder Responds to Orchard Vulnerability: No Signs of Theft, Orchard Pool to Be Sealed

ZEC Co-Founder Addresses Orchard Vulnerability: No Signs of Theft, Plans to Sunset Orchard Pool A security vulnerability was recently discovered in Zcash's Orchard shielded pool, raising key concerns. The primary questions are whether the flaw was exploited, if user funds are safe, whether users can verify the total ZEC supply, and if other similar vulnerabilities exist. Analysis suggests the vulnerability was likely not exploited prior to its discovery. It was found proactively by a researcher using specialized tools, not due to an active breach. The development team and mining pools acted quickly to contain the issue. Typical financially-motivated attacks would likely have left visible on-chain evidence, which has not been observed. User funds in Orchard are considered safe and should be recoverable, assuming no prior exploitation. If the flaw was never used, all legitimate funds can be withdrawn. The article outlines risks associated with moving funds to transparent addresses or other pools, but concludes that leaving assets in place is a reasonable option. Currently, users cannot independently verify that the total ZEC supply hasn't been inflated due to this bug. However, the planned Ironwood network upgrade is designed to resolve this. It will permanently close the Orchard pool to new deposits and internal transfers, allowing only withdrawals. This mechanism will cap total withdrawals at the amount of legitimately deposited funds, enabling anyone to cryptographically verify the supply post-upgrade. Multiple teams, including Shielded Labs, have conducted extensive audits focused on counterfeiting vulnerabilities, assisted by advanced AI tools. No additional flaws of this type have been found so far, increasing confidence that no other similar undisclosed vulnerabilities exist. In summary, evidence indicates the Orchard bug was probably not used, user funds are secure, and no other counterfeiting flaws are currently known. The upcoming Ironwood upgrade will restore users' ability to independently verify the total ZEC supply, closing this chapter.

Japan's Central Bank on the Verge of Raising Rates, Can the AI Bull Market Still Hold?

TL;DR: The impending Bank of Japan (BOJ) interest rate hike is shifting global market focus this week, raising questions about its potential impact on the AI-driven bull market and cryptocurrencies like Bitcoin. For years, the yen has served as a cheap global "funding currency," enabling carry trades where investors borrowed yen at low rates to buy higher-yielding assets. This dynamic amplified liquidity and risk appetite in global markets, benefiting high-beta assets like AI tech stocks and crypto. The BOJ's expected move to raise rates from 0.75% to 1.0% signals a shift away from this era of ultra-low-cost funding. The core concern isn't the 1% rate itself, but the direction of change and its potential to reduce global leverage and risk tolerance. An unwinding of yen carry trades could force investors to sell global assets to buy back yen for repayment, potentially triggering synchronized volatility in overvalued sectors. While AI fundamentals and crypto-specific drivers remain intact, the market impact will depend on whether the BOJ signals a faster-than-expected pace of normalization. Post-decision, watch for correlations between a strengthening yen, rising Japanese bond yields, and simultaneous pressure on tech stocks and cryptocurrencies to gauge if the market is pricing in a broader tightening of cheap global liquidity.

Microsoft Announces Commercial-Grade Quantum Computer to be Completed in Three Years: Will the Boots Land?

Microsoft announces plans to build a commercially viable quantum computer by 2029, a significant acceleration from the previous industry consensus of a decade. The breakthrough is fueled by their new Majorana 2 quantum chip, which boasts a record-breaking average qubit lifetime of 20 seconds—a 1,000-fold reliability improvement over its predecessor. This leap was achieved by leveraging topological qubits, a theoretically more stable technology using Majorana zero modes, and switching the core superconducting material from aluminum to lead. Crucially, Microsoft's "Discovery" agentic AI platform accelerated the R&D process. AI agents autonomously analyzed vast experimental data, optimized manufacturing parameters (like the lead alloy composition), and solved issues like "ghost noise," dramatically speeding up experimentation. While the 20-second coherence time is a landmark, challenges remain: scaling from 12 qubits to the millions needed for practical applications, managing compilation costs, and verifying quantum results. Skeptics call for peer-reviewed data, and questions persist about whether even 20 seconds is sufficient for complex algorithms like breaking RSA encryption. The race is on with other approaches (superconducting, trapped ions), but Microsoft's confidence in its topological roadmap signals a potential shortcut to a scalable quantum future.

What Kind of People Is Anthropic Actually Hiring? Insights from 1,680 Resumes Provide the Answer

Contrary to the common perception of Anthropic as a PhD-heavy AI research lab, an analysis of 1,680 engineer profiles reveals its core talent is experienced "builders." The engineering team, largely assembled in the past 18 months (median tenure 10 months), hires senior engineers with a median of 12.2 years of prior experience. They primarily come from major engineering-focused companies like Google, Meta, Amazon, Microsoft, Stripe, Databricks, Snowflake, and Palantir, not primarily from other AI labs. Their backgrounds are infrastructure-heavy (40%), focusing on backend, distributed systems, databases, and security, with skills like Python, Java, C++, and AWS being common. Only 13.7% hold PhDs. The dominant job title is "Member of Technical Staff." For early-career hires (<6 years experience), entry is not based on standard work history but on prestigious signals: top internships (e.g., at FAANG or quant trading firms), competition rankings, research publications, or AI safety fellowship experience. The key insight for applicants is to present as infrastructure builders, highlighting experience with large-scale systems, not as pure researchers, reflecting Anthropic's identity as a highly engineered infrastructure company.

Is There Really a "World Cup Curse" in the Market?

Is there really a "World Cup Curse" affecting markets? Historical data shows global equity markets often underperform during the tournament. The S&P 500 has averaged negative returns of -1.5% to -2.11% across 19 World Cups since 1950, with declines in 58% of events. China's Shanghai Composite fell in 71% of tournaments since 1994. Studies confirm reduced trading activity during matches, with volumes dropping significantly, especially when a home nation plays. A team's loss can also lead to negative sentiment and selling pressure in its domestic market the next day. However, the "curse" may be partly attributed to seasonal weakness. Many tournaments are held in June-July, a historically weaker period for stocks ("Sell in May and go away"). The 2022 Qatar World Cup, held in November-December, saw a smaller drop in trading volume compared to summer events, suggesting timing plays a role. The cryptocurrency market's performance during World Cups has been mixed and largely driven by its own major catalysts (e.g., Mt. Gox hack, FTX collapse, halving cycles) rather than the tournament. Investment opportunities have shifted over time. Traditional beneficiaries like TV manufacturers have seen fading returns as streaming platforms become the core viewing channel. Classic consumer plays like beer and sportswear face challenges from changing consumption trends. Newer digital assets, like fractionalized collectible player cards on blockchain, have seen explosive growth. While gambling is a traditional sector, prediction markets are emerging. In conclusion, while a statistical correlation exists, the World Cup's direct impact on markets is likely limited and intertwined with seasonal patterns. With lower liquidity during the event, the simplest strategy for many might be to step back from trading and enjoy the games.
