REX Shares took a “regulatory end-around” with its Ethereum and Solana staking ETF filings, and the launch looks “imminent,” an ETF analyst says.
ETH holds on to the bulk of its weekly gains, while BTC and altcoins sell off.
Mayor Eric Adams’s push for a Bitcoin-backed municipal bond faces strong opposition from Comptroller Brad Lander, who found the plan "legally dubious and fiscally irresponsible."
The payouts to FTX creditors have sparked both controversy and speculation that the payouts could be reinvested back in the crypto markets.
Institutional demand for Bitcoin and increasing regulatory clarity are positive factors for Bitcoin in 2025, head of research Katalin Tischhauser says.
Bitcoin’s chance of falling to $100,000 has increased, but the $3.7 billion open interest wipeout means traders will view dips as buying opportunities.
Key takeaways:
97% of ETH put options will expire worthless if ETH holds above $2,600.
A bullish ETH price outcome could be limited by macroeconomic factors and trading strategies that cap Ether gains.
On May 30, $2.4 billion in Ether (ETH) options will expire—an event that could support ETH’s attempt to break above the $2,700 mark for the first time in over three months. Despite the recent gains, Ether is down 21% in 2025, while the broader cryptocurrency market has seen a 5% increase.
Ether bulls are motivated to keep ETH above $2,600 ahead of the monthly expiry. However, weak network activity on Ethereum suggests that the upside potential may be limited.

The US Labor Department has officially rescinded guidance issued during the Biden administration that limited the inclusion of cryptocurrency in 401(k) retirement plans.
On May 28, the Labor Department revoked a 2022 guidance that had urged fiduciaries to be “extremely cautious” when considering cryptocurrency for 401(k) retirement plans. The move could give asset managers more flexibility to include digital assets in retirement investment options.
The government agency removed the guidance asserting that it represented a departure from the department’s “historically neutral, principled-based approach to fiduciary investment decisions.”
“We’re rolling back this overreach and making it clear that investment decisions should be made by fiduciaries, not D.C. bureaucrats,” said US Secretary of Labor Lori Chavez-DeRemer.
The Labor Department under Biden criticized the practice of marketing cryptocurrencies to 401(k) participants. At the time, the agency claimed cryptocurrencies posed “significant risks and challenges” to participants’ retirement accounts due to their “speculative and volatile” nature and “valuation concerns,” among other reasons.

Key takeaways:
Bitcoin researcher Sminston With says BTC could gain 100% to 200%, with a cycle peak between $220,000 to $330,000.
Bitcoin continues to exhibit strong cyclical volatility, contradicting the belief that its price swings are softening over time.
Over $4 billion in BTC has been moved by long-term holders, warning of a price correction.
Analysis from Bitcoin (BTC) researcher Sminston With implied that a BTC price peak is still 100% to 200% away from current prices. In a recent X post, With shared a Bitcoin price chart using a 365-day simple moving average (SMA) aligned with a power law model (R²=0.96).

Bilal Bin Saqib, head of Pakistan’s crypto council, announced on May 28 that the country is moving to establish a strategic Bitcoin reserve.
Speaking at the Bitcoin 2025 conference in Las Vegas, Nevada, Saqib said the government of Pakistan followed the United States’ lead in establishing a Bitcoin strategic reserve and is embracing pro-crypto regulatory policies. The government official told the audience:
"Today is a very historic day. Today, I announce the Pakistani government is setting up its own government-led Bitcoin Strategic Reserve, and we want to thank the United States of America again because we were inspired by them."The announcement represents a significant departure from the government of Pakistan’s previous stance on cryptocurrencies, holding that crypto would never be legal in the country.
Pakistan’s shift reflects the broader trend of nation-states adopting pro-crypto policies following the regulatory shift in Washington, DC under the President Donald Trump administration.

Shares of video game and collectibles retailer GameStop dropped nearly 11% on May 28 after the company announced its first Bitcoin purchase, triggering a classic sell-the-news reaction.
The stock closed at $31.21 on the New York Stock Exchange, according to Google Finance.
The company announced the purchase of 4,710 Bitcoin (BTC) valued at roughly $513 million on May 28. GameStop confirmed plans to create a BTC treasury strategy on March 26, following months of investor speculation and rumors that it would begin accumulating the cryptocurrency.
Trump Media and Technology Group (TMTG), the parent company of President Donald Trump’s Truth Social platform, also saw its shares plunge after announcing a $2.5 billion capital raise to purchase Bitcoin. Since the May 27 announcement, TMTG stock has dropped over 24%.

Key point:
Bitcoin’s market structure is still bullish, even as a phase of profit taking and consolidation sets in.
Bitcoin (BTC) remains pinned below the breakout level of $109,588, indicating that the bears are fiercely defending the level. Bitfinex analysts said in a market note that profit-taking generally follows after Bitcoin hits a new all-time high after a sharp rally. The report added that a mild retracement or consolidation would be healthy and lay the foundation for the next leg higher.
Glassnode had a similar view. In its latest report, the market intelligence company said that the relative strength indicator (RSI) has weakened, suggesting easing momentum, which could lead to “a potential pause or reversal in the recent bullish trend.”

United States Vice President JD Vance took the stage to deliver a keynote address at the Bitcoin 2025 conference in Las Vegas, Nevada, encouraging Bitcoiners to deepen their involvement in politics.
Vance highlighted the strategic and geopolitical importance of Bitcoin, emphasizing that the US should maintain leadership in the crypto industry to remain competitive in the age of digital finance. Vance told the audience:
"What happens in the world of politics, what happens in the world of bureaucracy, will affect even the most transformational and valuable technologies if we do not make the right decisions. The first thing that I would ask you, is to take the momentum of your political involvement in 2024 and carry it forward to 2026 and beyond."“Don’t ignore politics because I guarantee you, my friends, politics is not going to ignore this community, not now, and not in the future,” the vice president continued.

Conduit, a cross-border payments company based in Boston, has raised $36 million in a Series A funding round led by Dragonfly and Altos Ventures. The capital will go to scale its payment system and expand currency offerings across fiat and stablecoins.
Conduit markets its payment system as an alternative to the messaging network SWIFT, or Society for Worldwide Interbank Financial Telecommunications. Banks have relied on the SWIFT protocol to process wire transfers since the 1970s.
Conduit claims its platform offers a modern alternative, enabling near real-time cross-border settlements by combining stablecoins with local fiat currencies through crypto infrastructure.
“Traditional cross-border payment systems do not meet the demands of modern businesses,” Kirill Gertman, Conduit CEO, said in a statement.
Additional participants in the funding round include Sound Ventures, Commerce Ventures, DCG, Circle Ventures, and two previous investors, Helios Digital Ventures and Portage Ventures. Conduit claims its clients have saved more than 60,000 hours in settlement times and over $55 million in fees since launching in 2021.

BlackRock is reportedly planning to take a significant stake in Circle’s upcoming initial public offering (IPO).
According to a May 28 Bloomberg report citing anonymous sources, BlackRock is looking to purchase roughly 10% of the offering. Circle, the issuer of the USDC stablecoin, is aiming to raise $624 million in its initial public offering
Cathie Wood’s Ark Investment Management is also interested in buying $150 million worth of shares in the offering, the report said.
Circle launched its offering of 24 million shares of Class A common stock on May 27. The offering consists of shares from the company as well as shares of existing stakeholders, including co-founder and CEO Jeremy Allaire. According to the report, Circle’s IPO has now received orders for multiple times the shares available.
The company filed for an initial public offering on April 1, but delayed plans citing economic uncertainty. Crypto firms Ripple and Coinbase were reportedly exploring a potential acquisition of Circle. The company has since dismissed the speculation, saying it “is not for sale.”

Coinbase, America’s largest cryptocurrency exchange, received an unsolicited email from an unknown threat actor on May 11, 2025. They claimed to possess sensitive information about its customers and demanded a ransom of $20 million.
Before examining the breach, it is interesting to understand how it happened at a public company that spends millions monthly on cybersecurity. In February, blockchain investigator ZachXBT reported increased thefts involving Coinbase users. He blamed aggressive risk models and pointed out Coinbase’s failure to prevent $300 million in yearly losses from social engineering scams.
A table ZachXBT shared on X showed $65 million stolen from users between December 2024 and January 2025. He also said the real losses could be higher, as his data only came from his direct messages about onchain thefts, and excluded Coinbase support tickets and police reports he couldn’t access.
The fear of cybercriminals stealing valuable information came true on May 11 when Coinbase published a blog post confirming that account balances, ID images, phone numbers, home addresses and partially hidden bank details were stolen during the data breach.

Cork Protocol, a decentralized finance (DeFi) platform, was hit by a smart contract exploit on May 28, resulting in the loss of roughly $12 million in digital assets.
Cybersecurity firm Cyvers said the hack occurred at 11:23:19 UTC and was funded by an address ending in “762B.” According to the firm, the attacker used the exploit to steal roughly 3,761 Wrapped Staked Ether (wstETH), which was converted to Ether (ETH) almost immediately after the attack.
“We are investigating a potential exploit on Cork Protocol and are pausing all contracts. We will report back with more information,” Cork Protocol co-founder Phil Fogel wrote on X.

A new proposal to install Bitcoin ATMs in federal buildings highlights an important question: Can crypto truly go mainstream without a stronger physical presence? For years, the industry has focused on software and decentralization, but its reluctance to invest in real-world infrastructure is starting to show. Without physical access points, crypto risks becoming an exclusive, insiders-only system, rather than the open alternative it sets out to be.
Everyone loves to talk about decentralization. There’s a good reason behind this. It defines the movement, shapes the technology, and supports the vision of a better financial system. While the industry focuses on code and algorithms, it lacks something basic. A decentralized system that exists only online is not genuinely decentralized.
Bitcoin’s physical infrastructure is the missing link. Without tools like ATMs, kiosks and access points at traditional retail locations, crypto remains out of reach for millions. Decentralization is not just about removing intermediaries. True decentralization requires expanding access. Without real-world touchpoints, even the most advanced network becomes limited to a closed circle of insiders.

The Katana Foundation, a nonprofit focused on decentralized finance (DeFi) development, is launching its private mainnet, aiming to unlock greater crypto asset productivity via deeper liquidity and higher yields for users.
The Katana Foundation launched a DeFi-optimized, private blockchain, Katana, on May 28, incubated by GSR Markets and Polygon Labs, with the public mainnet launch set for June.
The new blockchain will enable users to earn higher yields and explore DeFi in a “unique, optimized yield environment” that unlocks latent value through an ecosystem that makes every digital asset “work harder,” according to an announcement shared with Cointelegraph.
“DeFi users deserve ecosystems that prioritize sustainable liquidity and consistent ‘real’ yields,” wrote Marc Boiron, the CEO of Polygon Labs and core contributor at Katana, adding:
“Katana’s user-centric model turns inefficiencies into advantages, establishing a truly positive-sum environment for builders and participants alike."Source: KatanaKatana aims to solve the crypto industry’s liquidity fragmentation issue, which can cause significant price slippage, as one of the main barriers limiting institutional DeFi participation

Scammers prey on seniors because they view them as financially secure, trusting and less familiar with rapidly evolving technology.
Let’s understand why seniors are key targets.
Perception of wealth: Many older adults have retirement savings or pensions, making them lucrative targets.Lower tech fluency: Navigating crypto wallets, private keys and blockchain concepts can be intimidating, something scammers exploit.Embarrassment prevents reporting: Victims often feel ashamed, making them less likely to report the crime.Crypto is irreversible: Once funds are sent via Bitcoin or another cryptocurrency, there’s no reversing the transaction. That’s a dream scenario for scammers.According to the Federal Trade Commission (FTC), seniors report growing losses linked to cryptocurrency investment fraud, romance scams and government impersonation. In South Carolina’s Beaufort County alone, seniors reported over $3.1 million in crypto scam losses in 2024.
And these scams are becoming more sophisticated. AI tools can now clone voices, spoof caller IDs and create fake websites that mimic legitimate exchanges or financial institutions to steal from unsuspecting seniors.

Top Bitcoin (BTC) bulls in 2025 have updated their price forecasts, and they range from a relatively cautious $130,000 to seven-figure moonshots.
Familiar doubters like gold bug Peter Schiff and economist Nouriel Roubini continue to predict a catastrophic ending for the world’s largest cryptocurrency. Meanwhile, Bitcoin spent the year with record-breaking rallies behind renewed institutional uptake.
It set a new all-time high of $111,970 on May 22 and has been trading near that level since, teasing investors with the possibility of a new ceiling.
Here are some of the boldest Bitcoin price predictions from the first half of 2025 (so far).
Bitcoin has stormed back since dropping to 2025 lows of $76,300 in April.

In March, the White House did just that, though it has yet to be codified into law by Congress.

The United Kingdom’s Financial Conduct Authority (FCA) has requested public feedback on proposed regulations for stablecoins and cryptocurrency custody.
In a May 28 request for comment, the United Kingdom’s financial regulator announced that its regulatory proposals are “the latest milestone on the road to crypto regulation.” The draft rules are based on prior roundtables and industry feedback. David Geale, executive director of payments and digital finance at the FCA, said the agency aims to support innovation while ensuring market trust:
“At the FCA, we have long supported innovation that benefits consumers and markets. At present, crypto is largely unregulated in the UK. We want to strike a balance in support of a sector that enables innovation and is underpinned by market integrity and trust.”The FCA also noted it will work with the UK’s central bank to regulate stablecoins. Bank of England Deputy Governor Sarah Breeden said, “For those stablecoins that expect to operate at systemic scale, the Bank of England will publish a complementary consultation paper later this year.”

The FCA said that its rules “aim to ensure regulated stablecoins maintain their value.” The regulator said customers must be clearly informed about how the backing assets are managed. It also recommended that stablecoin issuers appoint independent third-party custodians to hold reserve assets:

Non-fungible tokens (NFTs) caught an uptick in sales in May after months of consistent decline throughout 2025.
Data from CryptoSlam shows that May’s NFT sales climbed to $430 million, up from $373 million in April, a 15% increase. It marks the first monthly sales increase this year, suggesting renewed interest in digital collectibles.
This follows a five-month decline in sales since volume peaked at over $900 million in December 2024. May also had the highest number of transactions in 2025, reaching 5.5 million, according to CryptoSlam.
The sales uptick may be attributed to the divergence between unique NFT buyers and NFT sellers. NFT buyers continued to increase in May, while sellers declined.

Sui (SUI) is making a strong technical case for a 100% price rally in the coming weeks, helped further by a slew of optimistic updates, such as the recent Nasdaq ETF filing with the US Securities and Exchange Commission (SEC).
As of May 28, SUI has reclaimed the “Gooner EMA” as support on the weekly chart.
