Republican Senator Thom Tillis signaled on Sunday that he will no longer block Kevin Warsh’s bid to become Federal Reserve chair, following the conclusion of a Department of Justice probe into Jerome Powell related to the Fed’s headquarters renovation. In a post on X, Tillis said the three-month DOJ inquiry has closed and that he is “looking forward” supporting Warsh’s confirmation.

“I have been clear from the start: the U.S. Attorney’s Office criminal investigation into Chair Powell was a serious threat to the Fed’s independence, and it needed to end before I could support Kevin Warsh’s confirmation,” Tillis wrote, adding that he welcomes the inspector general’s investigation as a necessary and appropriate measure, and that he expects it to be conducted thoroughly and professionally.

Tillis, a Republican on the Senate Banking Committee, held significant leverage to slow or block Warsh’s appointment by employing a procedural hold or withholding his vote to prevent advancement to a full Senate floor vote. The development aligns with a broader regulatory and policy environment as the Fed prepares for a leadership transition.

Powell’s tenure is scheduled to end May 15, with Warsh anticipated to assume the role in the days that follow once confirmed by the full Senate. The Senate Banking Committee has set its vote for April 29, while the timing of the full Senate confirmation remains unsettled and could occur during the week of May 11.

Related reporting notes broader policy momentum surrounding crypto regulation and central bank policy debates in the United States. The discussion comes as lawmakers weigh how a new Fed chair might influence rates and financial stability, with potential indirect implications for digital assets and crypto market structure.

There has been ongoing debate about how Warsh’s leadership at the Federal Reserve could affect the crypto market. Warsh, a former Fed governor, has been characterized in coverage as hawkish on some fiscal policy questions and skeptical about aggressive easing, a stance that could influence risk appetite for higher-beta assets, including cryptocurrencies. Yet, observers note that policy independence remains a core premise of the Fed, and Warsh has said that decisions will be made independently of political pressure.

Warsh is also regarded as crypto-friendly relative to some peers. His public disclosures show exposure to more than 30 crypto projects, including assets such as Solana and decentralized exchanges like dYdX. This background has been cited by observers as potentially shaping his approach to crypto policy and industry engagement, though no policy positions have been formally announced beyond adherence to Fed independence and regulatory rigor.

Source data and coverage indicate that the nomination process is proceeding under standard Senate oversight, with a clear path toward a formal vote by the Banking Committee and a subsequent floor vote. As reported, the transition timeline remains contingent on committee outcomes and Senate scheduling, with a federal leadership handover anticipated in mid-May if confirmations proceed smoothly.

According to Cointelegraph, the broader regulatory discourse continues to intersect with crypto-market participants, institutional investors, and financial institutions seeking clarity on policy direction, licensing expectations, and cross-border oversight. The unfolding confirmation process thus sits at the nexus of monetary policy, financial regulation, and crypto market structure considerations.

Cutting Through the Illusion of “Easy Yield” in Decentralised Finance

Decentralised Finance (DeFi) has reshaped how individuals interact with money—removing intermediaries, enabling permissionless access, and introducing new forms of earning. Yet beneath the surface of high annual percentage yields (APYs) and “passive income” narratives lies a more complex reality. Many participants chase returns without fully understanding where those returns originate—or the risks attached.

This article breaks down practical DeFi strategies that actually make sense, separating sustainable mechanisms from misleading hype.

1. Yield Farming: Real Returns vs. Inflated APYs

Yield farming refers to deploying crypto assets across DeFi protocols to earn rewards, often in the form of additional tokens. While advertised APYs can appear extremely attractive—sometimes reaching triple or even quadruple digits—these figures are often misleading.

Where real yield comes from:

• Trading fees generated by decentralised exchanges
• Interest paid by borrowers in lending markets
• Protocol revenue shared with liquidity providers

Where “fake” yield comes from:

• Token emissions (printing new tokens as rewards)
• Short-term incentives designed to attract liquidity
• Unsustainable reward structures that collapse once incentives are reduced

The key distinction is sustainability. If returns rely primarily on newly minted tokens rather than real economic activity, the yield is likely temporary. Once token prices drop or emissions slow, returns can evaporate quickly.

2. Liquidity Providing and Impermanent Loss (Explained Clearly)

Providing liquidity involves depositing token pairs on decentralised exchanges such as Uniswap. In return, users earn a share of trading fees.

However, this strategy introduces a critical risk known as impermanent loss.

What is Impermanent Loss?

Impermanent loss occurs when the prices of the deposited assets change relative to each other. The automated market maker (AMM) adjusts token ratios to maintain balance, which can result in a lower value compared to simply holding the assets.

Simple Example:

• You deposit ETH and USDC into a pool
• ETH price doubles
• The pool automatically sells some ETH to maintain balance
• You end up with less ETH than if you had just held it

Even though you earn fees, they may not always offset the loss—especially during volatile market conditions.

Key Insight:
Liquidity providing works best in low-volatility pairs (e.g., stablecoin pairs) or when trading volume is high enough to generate meaningful fees.

3. The “Passive Income” Myth in DeFi

DeFi is often marketed as a source of passive income, but this framing can be misleading.

In reality, DeFi requires:

• Active monitoring of positions
• Understanding of smart contract risks
• Awareness of changing incentives and tokenomics
• Risk management during market volatility

Returns are not fixed. Strategies that appear profitable today may become unviable tomorrow due to:

• Declining token prices
• Reduced trading volume
• Protocol changes or exploits

Calling DeFi “passive” is like calling trading “set-and-forget”—technically possible, but rarely wise.

4. Core Platforms Explained Simply

Uniswap

A decentralised exchange (DEX) that allows users to swap tokens directly from their wallets. Instead of traditional order books, it uses liquidity pools. Users who provide liquidity earn fees from trades executed in those pools.

Use Case:

• Token swaps
• Liquidity provision for fee generation

Aave

A lending and borrowing protocol where users can deposit assets to earn interest or borrow against collateral.

How it works:

• Lenders supply assets and earn interest
• Borrowers take loans by overcollateralizing their positions

Use Case:

• Earning yield through lending
• Leveraging positions without selling assets

5. What Actually Makes a DeFi Strategy “Sensible”?

A strategy in DeFi is not defined by its APY, but by its risk-adjusted return and sustainability.

Sensible strategies tend to:

• Rely on real economic activity (fees, interest)
• Avoid excessive dependence on token emissions
• Account for downside risks (price volatility, smart contract failure)
• Align with long-term protocol viability

Unsensible strategies often:

• Chase the highest APY without understanding the source
• Ignore risks like impermanent loss or liquidation
• Depend entirely on market hype and token inflation

Conclusion

DeFi offers powerful tools for generating yield, but it is not a shortcut to effortless wealth. Most returns come from identifiable sources—trading fees, borrowing demand, or incentives—and each carries trade-offs.

Understanding where yield originates is the difference between informed participation and speculation.

The reality is simple:
If the yield looks too good to be true, it usually is—and in DeFi, the market corrects that illusion faster than most expect.

France’s crackdown on violent, wallet-targeting crimes linked to crypto ownership has intensified, with 88 individuals indicted — including 10 minors — in connection with wrench attacks. National prosecutors say 75 suspects are in pre-trial detention, in a wave of arrests tied to 12 cases overseen by specialized investigating judges at the Paris Judicial Court and monitored by the National Prosecutor’s Office for Organized Crime (PNACO).

Wrench attacks are defined as the use of physical force to access a victim’s crypto wallet, often unfolding as home invasions, kidnappings or extortion attempts. PNACO data show a troubling rise in such incidents: 18 in 2024, 67 in 2025, and 47 already in 2026. Security firm CertiK noted a 75% increase in wrench-attacks worldwide in 2025 versus the prior year, underscoring a global expansion of this criminal tactic. The prosecutions, Perrée stressed, involve acts that are particularly serious due to both harm to individuals and the coercive methods used to obtain crypto transfers under duress.

Key takeaways

• 88 individuals indicted in France over wrench attacks against crypto owners, including 10 minors; 75 in pre-trial detention; 12 cases under investigation.
• Investigations indicate organized, structured networks rather than isolated incidents, with case consolidations revealing repeat offenders across multiple events.
• Global trend shows surging wrench-attacks: 2024 (18 incidents), 2025 (67), and 2026 (47 so far), with CertiK reporting a 75% rise in 2025 year-over-year.
• Officials caution crypto holders about visibility on social media and warn of impersonation scams targeting victims in the wake of investigations.

France expands a state-led effort to dismantle wrench networks

Perrée’s office disclosed that the arrests span a broad spectrum of cases that are now being examined by Paris’s specialized investigating judges, with PNACO supervising. The pre-trial detention rate — 75 suspects — signals strong judicial momentum as authorities pursue charges including arrest, abduction, organized group sequestration, extortion and attempted extortion. The prosecutor stressed that these acts are grave not only for the immediate harm inflicted on victims but also for the chilling effect they have on the crypto ecosystem and the willingness of individuals to engage in on-chain activity under duress.

Law enforcement have begun stitching together the threads of multiple cases after uncovering overlaps where some defendants appear in several wrench incidents. Perrée said that this consolidation, enabled by linking recurrent individuals across cases, reveals the existence of structured networks operating with shared tactics and potentially coordinated financial channels. Investigations remain ongoing under the authority of the investigating magistrates, with aims to identify all participants, map the flow of funds and dismantle the networks involved. Jameson Lopp, chief security officer at Casa, has long maintained a global ledger of wrench-attacks dating back to 2014, with 29 such incidents recorded this year.

Rising threat, rising awareness: what it means for users

The outbreak of wrench-attacks is not merely a courtroom matter; it has real implications for crypto holders who may face duress-based coercion when transferring assets. Perrée urged crypto owners and their families to exercise heightened vigilance and to avoid overexposure on social networks, which could make them targets. She also warned against scammers posing as investigative services or judicial authorities seeking to obtain information under false pretenses.

The broader context for this trend includes research from security firms noting the reasons wrench attacks have proliferated. TRM Labs highlighted last year that wrench-attacks have been rising due to perceived pseudonymity on the blockchain, visible wealth online and the ease with which attackers can harvest personal data. In related chatter around the motives, Telegram founder Pavel Durov attributed some of the uptick in France to alleged misuse of crypto investors’ tax data by a former tax official, a claim that fed into the ongoing public discourse around risk and protection in crypto-related crime.

From a policy perspective, the surge in wrench attacks has already prompted discussions about additional measures to safeguard crypto owners. France’s response appears to be moving toward stronger enforcement and public awareness campaigns designed to reduce the vulnerability of individuals, as authorities pursue reforms and deterrence at the intersection of finance, technology and criminal law. For context, policymakers have referenced broader developments around crypto safety and legality as they weigh new regulations intended to curb violent crypto crime.

Data points cited by security researchers also underscore the evolving nature of this threat. A list maintained by Lopp shows 29 wrench-attacks recorded in 2026 so far, illustrating the spread of incidents beyond Europe and highlighting ongoing global exposure. The April period alone saw five recorded wrench-attacks, reflecting the persistence of this crime wave and the ongoing need for awareness and protective measures among crypto users.

What to watch next

As investigations continue, prosecutors are signaling a sustained effort to pierce the networks behind wrench-attacks and to trace the financial channels that move crypto under duress. Investors and users should monitor updates from PNACO and French authorities, along with regulatory and security community guidance on risk mitigation, including cautious social-media behavior and vigilant verification when dealing with requests for information or transfers. The case also serves as a reminder of the real-world risks associated with financial sovereignty in crypto — and the importance of combining legal enforcement with practical security practices to protect assets and personal safety.

Readers should stay tuned for any new measures announced by French government officials in response to these kidnappings and extortion cases, as well as for continued reporting on how networks are being dismantled and how financial trails are being traced and disrupted.

Luxor Technology Corporation has expanded its partnership with MicroBT through a $100 million commitment to buy WhatsMiner bitcoin mining rigs. 

The deal strengthens ties between the mining infrastructure firm and the hardware maker. The companies announced the expanded agreement on Sunday. Luxor said the purchase commitment forms part of a broader plan to support miners using MicroBT machines.

As part of the agreement, MicroBT signed a term sheet to invest in Luxor through its investment manager, Inflection Technology Ltd. The companies did not disclose the size of the planned investment.

The move adds a financial link to the existing commercial relationship. It also places MicroBT closer to Luxor’s mining software, hardware and service operations.

LuxOS support expands to WhatsMiner rigs

Luxor will also add support for MicroBT WhatsMiner machines through its LuxOS firmware. The company said the rollout will happen in phases across supported mining rigs.

LuxOS can help miners manage power changes during curtailment periods while rigs continue hashing. Luxor said the firmware can complete power target changes within 30 to 60 seconds and improve ramp-up times.

Miners gain access to Luxor services

Operators using LuxOS on WhatsMiner rigs will also gain access to Luxor’s wider service suite. These services include its mining pool, hashrate derivatives, energy services and Luxor Commander for fleet management.

Lauren Lin, Luxor’s head of hardware and software, said,

“Our clients have been asking for WhatsMiner firmware for years, and we have shipped a product that is going to help deliver significant profitability and usability benefits.”

Luxor said its firmware already runs on more than 300,000 bitcoin mining rigs globally. The company has also expanded beyond mining hardware into GPUs, servers, storage and networking for miners building AI and high-performance computing systems.

A new study from London Business School and Yale University challenges the notion that prediction markets reflect crowd wisdom. Focusing on Polymarket, the researchers argue that a small cadre of well-informed traders drives most price discovery on these platforms.

According to the paper, roughly 3.5% of accounts generate the bulk of price discovery on Polymarket. The remaining majority trades actively but contributes little information; their losses tend to accrue to the informed minority. The study, authored by Roberto Gomez-Cram, Yunhan Guo, Theis Ingerslev Jensen, and Howard Kung and revised on April 25, relies on a sign-randomization approach that re-samples each account’s past trades 10,000 times to simulate profit and loss.

“Prediction market accuracy thus reflects the wisdom of an informed minority, not the wisdom of the crowd.”

Polymarket and other prediction markets have surged in crypto circles, with industry data suggesting monthly trading volumes commonly around $15 billion across markets spanning sports, elections, corporate results, and cultural events.

However, the rise of these platforms has drawn regulatory scrutiny amid concerns that insider trading could exploit confidential information. The authors note that prediction markets operate with less oversight than traditional securities markets, in part because many users are pseudonymous and contracts are narrowly defined around specific events.

“These features make prediction markets an attractive venue for trading on private information,” the authors write, highlighting a salient tension between market efficiency and potential misuse.

The “informed minority” and outsized profits

The study identifies the informed minority as comprising market makers and “skilled takers,” together capturing over 30% of total gains on prediction markets. On average, market-maker accounts earned about $11,830 per account in the period studied.

By contrast, roughly 69% of profit-takers fall into a category the authors call the “lucky winners,” who account for about 29% of all accounts. The remaining participants are the “unlucky losers,” who absorb the aggregate losses.

These dynamics echo earlier research suggesting that a small subset of traders can dominate profitability on Polymarket. A separate analysis published earlier this month by crypto analyst Andrey Sergeenkov estimated that just 0.015% of Polymarket traders achieve profits large and consistent enough to contemplate leaving their day jobs.

The broader takeaway is clear: while prediction markets can show high activity and liquidity, the actual informational value often hinges on a narrow group of participants rather than a democratic crowd signal.

Regulatory spotlight and market design implications

The authors’ findings arrive at a moment of intensified regulatory attention toward crypto prediction markets. Insiders trading on platforms like Polymarket and Kalshi has become a focal point for policymakers, who are weighing how to balance innovation with safeguards against confidential-information trading. The study notes that pseudonymity and narrowly defined contracts create structural vulnerabilities that could complicate enforcement and oversight.

For platform operators, the results raise practical questions about design choices, such as how to encourage broader participation without diluting the precision of price signals, and what kinds of disclosure or verification might enhance market integrity without eroding user trust.

Investors and users, meanwhile, should consider that a large portion of trading volume may reflect participation by less information-rich actors. As price discovery appears concentrated within a minority, capital decisions tied to these markets could be influenced more by information asymmetries than by the crowd-sourced wisdom some proponents hoped to see.

What to watch next

As regulators scrutinize insider-trading risk and as exchanges iterate on their market designs, readers should monitor how policy, enforcement, and platform innovations shape the accessibility and integrity of prediction markets. The core question remains whether safeguards can widen the circle of informed participation without dampening the very signals that keep these markets functional.

Source data and the study’s methodology are documented in the authors’ paper, which is available for reference as a revision published on April 25. For broader context on market volumes, industry data place monthly prediction-market activity around the $15 billion mark across the sector.
