April 28, 2026 — Crypto markets saw significant developments today. Bernstein analysts published a report on IREN’s shift from Bitcoin mining to AI cloud services. A new Blockchain for Europe study argues that MiCA regulations have made euro stablecoins safe but commercially weak. French authorities indicted 88 people for wrench attacks on crypto owners.
Bernstein Analysts: IREN AI Cloud Pivot Reshapes Mining Economics
Bernstein analysts released a research report Monday examining IREN’s business model transformation. The firm is moving beyond Bitcoin mining into AI infrastructure. This follows a multi-billion-dollar deal with Microsoft.

Data from Bernstein shows IREN’s AI cloud division has contracted around 150,000 GPUs. These contracts support an estimated $3.7 billion in annual revenue once fully operational. A long-term agreement with Microsoft commits GPU capacity for AI workloads over five years.
The deal includes substantial customer prepayments. These funds help finance the infrastructure buildout. IREN’s total GPU investment is roughly $5.8 billion.

Funding sources include Microsoft prepayments and GPU-backed financing facilities. Additional cash and capital sources keep borrowing costs relatively low. Bernstein expects this shift to fundamentally reshape IREN’s business model.
Industry watchers note that IREN’s AI cloud revenue will likely become its primary income source in coming years. This signals a broader trend among Bitcoin miners diversifying into high-performance computing.
The implication is that traditional mining economics are evolving. Companies with access to cheap power and data center expertise are well-positioned to capture AI demand.
MiCA Regulations: Euro Stablecoins Safe But Commercially Weak
A new report from industry group Blockchain for Europe argues that MiCA has produced euro-denominated stablecoins that are ultra-safe but commercially weak. The report was released Monday.
DeFiLlama data cited in the report shows euro stablecoins account for less than 1% of global stablecoin volume. This is despite the euro’s much larger role in global markets.
The report argues that MiCA has pushed euro stablecoins onto the “downward-sloping” part of a regulatory Laffer curve. Stricter rules reduce the activity they are meant to govern.
Drafted by European Central Bank official Ulrich Bindseil and Blockchain for Europe’s Erwin Voloder, the report focuses on MiCA’s rules for euro electronic money tokens (EMTs). These tokens must be fully backed and are barred from paying interest.
That remuneration ban was designed to prevent stablecoins from becoming deposit substitutes. But the authors say it leaves MiCA-compliant euro tokens “at a particular disadvantage” in a positive-rate environment.
This is especially true versus bank deposits and foreign currency stablecoins that can embed or distribute yield through other mechanisms. The combination of strict safeguards and zero interest has created a safe but structurally uncompetitive euro stablecoin segment.
What this means for investors is that euro stablecoins may struggle to gain traction in trading and payments. The report places these constraints in a broader policy debate over how MiCA compares with other jurisdictions.
Regulatory Laffer Curve: How MiCA Affects Market Activity
The concept of a regulatory Laffer curve suggests that beyond a certain point, stricter rules reduce the activity they aim to govern. The report argues MiCA has crossed that threshold for euro stablecoins.
Data from DeFiLlama shows that while euro stablecoin supply has grown modestly, their share of global volume has declined. This suggests that compliance costs and restrictions are pushing users toward alternatives.
Industry watchers note that US dollar-pegged stablecoins continue to dominate trading and payments. They benefit from less restrictive regulatory frameworks in other jurisdictions.
The report calls for reforming MiCA to allow euro stablecoins to compete more effectively. This could include permitting interest payments or other yield mechanisms.
France Indicts 88 People for Crypto Wrench Attacks
French authorities have indicted at least 88 people, including 10 minors, in connection with alleged wrench attacks against crypto owners. Vanessa Perrée, the country’s national prosecutor for organized crime, made the announcement Friday.
Perrée said 75 of the alleged offenders are being held in pre-trial detention. The arrests relate to 12 cases currently under investigation by specialized investigating judges of the Paris Judicial Court.
The cases are monitored by the National Prosecutor’s Office for Organized Crime (PNACO). Wrench attacks involve the use of physical force to gain access to a victim’s crypto wallet.
These attacks have taken the form of home invasions, kidnappings, and other extortion attempts. PNACO has recorded 18 incidents in 2024, 67 in 2025, and 47 so far in 2026.
Blockchain security company CertiK reported a 75% increase in attacks worldwide in 2025 compared with the previous year. This suggests the problem is growing rapidly.
“The acts in question, particularly under the legal classifications of arrest, abduction, organized group sequestration, extortion, and attempts of organized group extortion, are of particular seriousness,” Perrée added.
She noted the harm caused to individuals and the methods used to obtain transfers of crypto-assets under duress. The indictments represent a significant law enforcement action against crypto-related violent crime.
Wrench Attacks: A Growing Threat to Crypto Owners
Wrench attacks have become a serious concern for crypto holders worldwide. Unlike digital hacks, these attacks involve physical violence or threats.
Victims are often targeted because attackers believe they hold significant crypto assets. The attacks can occur at home, in public, or through elaborate kidnapping schemes.
Security experts recommend that crypto holders take precautions. These include using multi-signature wallets, avoiding public disclosure of holdings, and maintaining physical security measures.
The rise in such attacks highlights the importance of personal safety in the crypto space. It also underscores the need for law enforcement agencies to develop specialized capabilities.
Conclusion
Crypto news today covers three major developments. Bernstein analysts see IREN pivoting from Bitcoin mining to AI cloud services, reshaping mining economics. MiCA regulations have made euro stablecoins safe but commercially weak, leaving the bloc behind US dollar-pegged tokens. French authorities have indicted 88 people for wrench attacks, highlighting the growing threat of physical violence against crypto owners. These stories illustrate the evolving environment of crypto regulation, business models, and security challenges.
FAQs
Q1: What is IREN’s pivot to AI cloud?
IREN is transitioning from Bitcoin mining to providing GPU capacity for AI workloads. It has a multi-billion-dollar deal with Microsoft and expects AI cloud revenue to become its primary income source.
Q2: Why are euro stablecoins considered safe but weak under MiCA?
MiCA requires full backing and bans interest payments on euro stablecoins. This makes them ultra-safe but commercially uncompetitive compared to US dollar-pegged tokens that can offer yield.
Q3: How many people were indicted in France for crypto wrench attacks?
At least 88 people, including 10 minors, have been indicted. They are connected to 12 cases involving home invasions, kidnappings, and extortion to access crypto wallets.
Q4: What is a wrench attack in crypto?
A wrench attack involves using physical force or threats to compel a victim to transfer crypto assets. The name comes from the idea of threatening someone with a wrench to give up their private keys.
Q5: How can crypto owners protect themselves from wrench attacks?
Use multi-signature wallets, avoid publicly disclosing holdings, maintain physical security measures, and consider using privacy-enhancing tools to reduce visibility of transactions.
