Economist and author of The Bitcoin Standard, Saifedean Ammous, has weighed in on the ongoing debate over spam inscriptions on the Bitcoin network, suggesting he would “throw in a few sats” to fund a full-time developer focused on making Bitcoin spamming more difficult and expensive.

Ammous made the remarks in response to a thread initiated by the pseudonymous developer GrassFedBitcoin, who called for Bitcoin Core to merge pull request #28408, which would enable node operators to filter inscriptions more easily.

According to GrassFedBitcoin, the lack of inscription filtering tools contributes to unnecessary blockchain bloat and undermines Bitcoin (BTC)’s role as a monetary protocol.

“No one running a node wants to relay inscriptions,” he wrote, arguing that the OP_RETURN limit increases were justified in the past under false assumptions. He pushed for a configurable, default policy discouraging the use of Bitcoin for storing JPEGs rather than monetary data.

Blockstream CEO Adam Back challenged the proposal, describing inscription filtering as an “arms race.” He noted that spam data embedded in Bitcoin transactions can be endlessly modified using code structures, requiring constant updates to filtering tools.

Retired artist Ed Suman lost over $2 million in cryptocurrency earlier this year after falling victim to a scam involving someone posing as a Coinbase support representative.

Suman, 67, spent nearly two decades as a fabricator in the art world, helping build high-profile works such as Jeff Koons’ Balloon Dog sculptures, according to a May 17 report by Bloomberg.

After retiring, he turned to cryptocurrency investing, eventually accumulating 17.5 Bitcoin (BTC) and 225 Ether (ETH) — a portfolio that comprised most of his retirement savings.

He stored the funds in a Trezor Model One, a hardware wallet commonly used by crypto holders to avoid the risks of exchange hacks. But in March, Suman received a text message appearing to be from Coinbase, warning him of unauthorized account access.

After responding, he got a phone call from a man identifying himself as a Coinbase security staffer named Brett Miller. The caller appeared knowledgeable, correctly stating that Suman’s funds were stored in a hardware wallet.

United Kingdom crypto companies will need to collect and report data from every customer trade and transfer beginning Jan. 1, 2026 as part of a broader effort to improve crypto tax reporting, the UK government said.

Everything from the user’s full name, home address and tax identification number will need to be collected and reported for every transaction, including the cryptocurrency used and the amount moved, the UK Revenue and Customs department said in a May 14 statement.

Details of companies, trusts and charities transacting on crypto platforms will also need to be reported.

Failure to comply or inaccurate reporting may incur penalties of up to 300 British pounds ($398.4) per user. The UK Revenue and Customs department said it would inform companies on how to comply with the incoming measures in due course.

However, UK authorities are encouraging crypto firms to start collecting data now to ensure compliance readiness.

The new rule is part of the UK’s integration of the Organisation for Economic Development’s Cryptoasset Reporting Framework to improve transparency in crypto tax reporting.

Hong Kong police arrested 12 people involved in a cross-border money laundering scheme that relied on crypto and over 500 stooge bank accounts to launder HK$118 million ($15 million), local news outlets reported.

The syndicate was dismantled on May 15, resulting in the arrest of nine men and three women in mainland China and Hong Kong.

The suspects allegedly recruited others to open bank accounts to receive proceeds from fraud cases, which were then converted into crypto at crypto exchange shops to launder the illicit funds, Hong Kong Commercial Daily reported on May 17.

The criminal organization rented a residential unit in the Hong Kong neighborhood of Mong Kok to plan and carry out its money laundering activities. Of the $15 million laundered, more than $1.2 million was linked to 58 reported fraud cases.

Caught in action

The bust followed police surveillance on May 15, when two recruits left the syndicate’s Mong Kok base — one visiting a bank, the other an ATM — before both went to convert the cash into crypto at a crypto exchange shop in the neighborhood of Tsim Sha Tsui.

Public internet infrastructure is the critical speed and performance constraint on high-throughput blockchain networks, according to Austin Federa, co-founder and CEO of DoubleZero, a project developing high-speed fiber optic communication rails for blockchains.

"The downside of the public internet is it was never built for high-performance systems. It was always built for this sort of relationship of one big server talking to one little server," Federa told Cointelegraph in an interview at Consensus 2025. The executive explained:

"We have validators all around the world. Rotating leader schedules all the time. And then they switch from having to be massive consumers of data to extremely massive broadcasters of data. So that means that they need huge amounts of resources both on ingress and egress."

The executive added that the constraint posed by public internet infrastructure is now the limiting factor in blockchain performance and not compute power or software development.

Networks like DoubleZero will make blockchains faster, decrease spreads in decentralized finance (DeFi) trades, lower transaction fees, and open up new use cases for blockchain networks that were previously unavailable due to communication infrastructure constraints.

Moody's credit rating agency downgraded the credit rating of the United States government from Aaa to Aa1, citing the rising national debt as the primary driver behind the reduction in creditworthiness.

According to the May 16 announcement from the rating agency, US lawmakers have failed to stem annual deficits or reduce spending over the years, leading to a growing national debt. The rating agency wrote:

"We do not believe that material multi-year reductions in mandatory spending and deficits will result from the current fiscal proposals under consideration. Over the next decade, we expect larger deficits as entitlement spending rises while government revenue remains broadly flat."

The credit downgrade is only one degree out of the 21-notch rating scale used by the company to assess the credit health of an entity.

Despite the negative short to medium-term credit outlook, Moody's maintained a positive outlook on the long-term health of the United States, citing its robust economy and the status of the US dollar as the global reserve currency as strengths, reflecting "balanced" lending risks.

Michael James, the head of institutional business development at Douro Labs — the company that developed the Pyth high-speed blockchain oracle network — told Cointelegraph that oracle networks like Pyth are disrupting the $50 billion financial data industry that provides critical price information to exchanges, brokerages, trading firms, and other institutional entities.

In an interview at Consensus 2025, the executive said that Pyth Network's data pull model sets it apart from traditional pricing oracles, allowing customers to pay for data on demand, reducing costs for institutions reliant on real-time market data.

According to the executive, the financial data industry is currently monopolized by around eight major providers that continually raise prices on clients arbitrarily. James added:

"These data vendors have no competition in traditional finance, and so they have all the pricing power in the world. There is no substitutability; whether you are a banker or hedge fund and you are trading more or less — you still have to buy that data for compliance reasons."

The high costs of financial data stifle innovation and prohibit small to medium-sized businesses from taking part in the global financial services industry, further concentrating the sector in the hands of a few large players and preventing novel use cases from emerging.

South Africa’s Garden Route, famed for its lush forests, expansive beaches and charming towns, has become a testbed for Bitcoin adoption.

From Mossel Bay to Witsand and Plettenberg Bay to Knysna, Bitcoin has become popular among shop owners and travelers alike for a multitude of reasons.

“We’re seeing the early signs of a parallel, permissionless economy emerging across an entire region,” James Caw, founder of SimplB — a local crypto asset provider — told Cointelegraph, “where small businesses benefit from faster, lower-cost digital payments and where people have more options to earn, send and receive sound money securely.”

For tourists, the benefits are immediate: no currency exchange hassles, no international card fees, and the ability to pay instantly and securely. For locals, Bitcoin (BTC) offers a hedge against inflation, protection from currency volatility and new economic opportunities.

Here’s a taste of what a Bitcoin-friendly trip along the Garden Route is like.

Fintechs in the front, decentralized finance (DeFi) in the back: the DeFi Mullet.

Today’s fintech companies offer excellent user experiences but are constrained by traditional financial infrastructure — siloed, slow, expensive and inflexible. Meanwhile, DeFi provides lightning-fast, cost-effective, interoperable infrastructure but lacks mainstream accessibility.

The solution? Combine fintech’s distribution and user experience with DeFi’s efficient back end.

The mullet is inevitable

Fintech companies heavily rely on traditional financial (TradFi) infrastructure that is siloed, slow to deploy and run, and costly to maintain. This inefficiency limits their control over costs and product offerings and has potential infrastructure risks. Fintechs have a strong incentive to transition to building on autonomous, credibly neutral public infrastructure.

Bitcoin’s next explosive move could send the asset to $250,000 by the end of 2025, according to Scott Melker, a crypto analyst and host of The Wolf of All Streets podcast.

Speaking in a recent interview, Melker cited growing institutional interest and diminishing volatility as key factors that could drive the next leg up.

“250K this year, totally possible,” Melker said, adding that Bitcoin (BTC)’s volatility has declined significantly in recent years.

“It used to be about three times as volatile as the S&P. Now it’s less than two times.” He pointed to increased involvement from pension funds and ETF issuers as evidence of a more mature, stable market.

The shift, he argued, reflects a broader trend of institutional adoption. “The more institutional money, the more Wall Street money, the more long-term holders get involved, the less volatility there’s going to be,” Melker explained.

The US Securities and Exchange Commission (SEC) has held discussions with Everstake, one of the largest non-custodial staking providers globally, to explore clearer regulatory definitions around staking in blockchain networks.

The meeting, which also involved the SEC’s Crypto Task Force, comes at a time when over $193 billion in digital assets are staked across major proof-of-stake (PoS) networks.

However, despite the massive scale of participation, staking remains in a legal gray zone in the US as regulators wrestle with its classification under existing securities law.

The previous SEC administration also took enforcement actions against major players such as Kraken, Coinbase, and Consensys due to their staking services. The agency, under pro-crypto President Donald Trump, has recently dismissed these enforcement actions.

During the meeting, Everstake told the SEC that non-custodial staking should not be classified as a securities transaction. The company said that users maintain full control over their digital assets throughout the staking process and do not transfer ownership to a third party.

A man from Wellington, the capital city of New Zealand, has been arrested in connection with an FBI-led investigation into a global cryptocurrency fraud operation that allegedly stole $450 million New Zealand dollars ($265 million).

According to New Zealand Police, the man is one of 13 individuals charged after authorities executed search warrants across Auckland, Wellington, and California over the past three days.

The charges stem from allegations that members of an organized criminal group manipulated seven victims to obtain large amounts of cryptocurrency, which was then laundered through multiple platforms between March and August 2024.

The US Department of Justice has indicted the man under federal law, including charges of racketeering, conspiracy to commit wire fraud, and conspiracy to commit money laundering, per the announcement.

Panama City Mayor Mayer Mizrachi has hinted at establishing a city-level Bitcoin reserve in a cryptic post following his meeting with two of El Salvador’s Bitcoin policy leaders.

“Bitcoin Reserve,” Mizrachi wrote to X on May 16 after meeting El Salvador-based Bitcoiners Max Keiser and Stacy Herbert.

While Mizrachi didn’t share details about his discussions with Keiser and Herbert, the timing of the post came 11 days before the Bitcoin 2025 conference in Las Vegas, where Mizrachi is scheduled to speak.

The creation of a Bitcoin reserve in Panama City would follow a recently approved measure permitting the use of crypto for public payments, including taxes, fines and municipal fees.

Bitcoin (BTC), Ether (ETH), Tether (USDT) and USDC (USDC) will be accepted once the crypto-to-fiat payment rails are established, Mizrachi said at the time.

Paraguayan law enforcement has deported three individuals and arrested another for attempting to steal crypto miners at a facility near the country’s Itaipu hydroelectric dam.

According to a May 15 statement from Paraguayan prosecutor Irene Rolón, the men were caught by police soon after breaking into a locked section of Teratech SA’s facility in Coronel Bogado, leading to their arrest.

Prosecutors believe the men may have had ties to Teratech as independent contractors, but are still waiting on official confirmation from the company’s CEO.

The three deported were Chinese nationals Jinping Duan, Tian Jianyun and Zheng Guanglong, who did not have official entry records into the country. Paraguayan authorities and Interpol believe the men illegally entered through Brazil or Bolivia.

The other person arrested, Nahun María Velázquez Garcete, is a legal resident in Paraguay but is believed to be part of a criminal organization.

Key takeaways:

Traders expect a Bitcoin price pullback to $90,000, but a bull flag could break out to new highs if profit taking near the range highs reduces.

On-chain data suggests the current profit taking is too weak to extinguish Bitcoin’s current price momentum.

Bitcoin (BTC) price has spent the bulk of the week pinned below $104,000 to $105,000, which many analysts have labelled as a resistance zone, but an alternative view suggests that BTC is simply consolidating within a bull flag.

A bull flag is a continuation pattern that is characterized by a period of sideways price action following a sharp uptrend, and when the structure confirms or breaks from the trendline resistance, the uptrend continues. 

Crypto entrepreneurs and their families in France will receive enhanced security measures amid a recent rise in crypto-related kidnappings in the country, Politico reported.

According to the May 16 report, the measures include priority access to police emergency lines, home security assessments, and safety briefings from French law enforcement to ensure best practices are being followed.

France’s Interior Minister Bruno Retailleau introduced the security measures as part of a broader effort to counter the recent wave of attacks.

"These repeated kidnappings of professionals in the crypto sector will be fought with specific tools, both immediate and short-term, to prevent, dissuade and hinder in order to protect the industry.”

Law enforcement officers will also undergo "anti-crypto asset laundering training,” Retailleau noted.

Retailleau met with several local leaders from the crypto industry to discuss the measures following three crypto-related kidnapping incidents in recent months.

Tokenization could open new opportunities for retail investors to access traditionally restricted asset classes, according to Johann Kerbrat, senior vice president and general manager of Robinhood Crypto, who called it “very important for financial inclusion.”

Speaking at the Consensus 2025 event in Toronto, Kerbrat said that some real-world assets, such as real estate and private equity, are available only to up to 10% of the US population. “You need to be an accredited investor to invest in private equity right now,” he said.

“How many people can afford a house or an apartment in New York?” he elaborated. “But you can get a piece of it with fractionalization, through tokenization. And so we think it makes it a lot easier to be exchanged, a lot more accessible for everybody.”

Robinhood has been one of a handful of investment firms or brokerages that have explored RWA tokenization in recent months. Others include BlackRock, Franklin Templeton, Apollo, and VanEck.

RWA tokenization is often touted as a means to enhance financial accessibility, with most tokenized funds currently concentrated on the private credit and US treasury markets. According to RWA.xyz on May 16, the total market capitalization of onchain RWA is $22.5 billion across just 101,457 asset holders. On average, each holder owns $221,867 in onchain assets.

The Filecoin Foundation and Lockheed Martin Space have successfully transmitted data in space using a version of the InterPlanetary File System (IPFS) on a satellite orbiting Earth, Marta Belcher, president of the Filecoin Foundation, told Cointelegraph. 

Filecoin and Lockheed Martin adapted the system for use in space and successfully tested it, Belcher said during the Consensus 2025 conference in Toronto.

The IPFS enhances privacy and security compared to traditional web protocols, such as HTTP, by identifying data based on its content rather than its location. This has additional benefits for data transmission in space, Belcher said.

“The architecture is well-suited to space because it reduces delays, compensates for data corruption caused by radiation, and enables cryptographic verification to ensure data has not been tampered with,” she said.

The foundation is a nonprofit governing the decentralized cloud storage protocol Filecoin (FIL), which uses the IPFS web protocol to store data. Lockheed Martin is one of the world’s largest aerospace companies.

At least one partner at Sequoia Capital was reportedly impacted by the recent data breach among Coinbase users, suggesting that data from others at the venture capital firm may also have been compromised.

According to a May 16 Bloomberg report, Sequoia Capital Managing Partner Roelof Botha’s personal information available through his Coinbase account was stolen after a group of cybercriminals bribed the exchange’s support agents for access to user data. Though Botha had not publicly disclosed his net worth, estimates suggested he had hundreds of millions of dollars in assets.

Coinbase disclosed the data breach in a May 15 blog post, saying that some of its users had been targeted with social engineering attacks after the criminals had access to their personal account information. The company said the group attempted to extort $20 million in exchange for not disclosing the breach, which Coinbase rebuffed.

Though the extent of the breach was still unknown, another Bloomberg report suggested that the same type of attacks targeted users at Kraken and Binance. Cointelegraph reached out to representatives from both exchanges but had not received responses at the time of publication.

Solv Protocol has launched a yield-bearing Bitcoin token on the Avalanche blockchain, giving institutional investors more exposure to yield opportunities backed by real-world assets, or RWAs.

On May 16, the protocol unveiled SolvBTC.AVAX, a token that connects Bitcoin (BTC) to real-world assets like US Treasurys and private credit offered by BlackRock and Hamilton Lane. 

The new token was developed through a seven-way partnership involving Solv, Avalanche, Balancer, Elixir, Euler, Re7 Labs, and LFJ, the company said. 

Solv Protocol founder Ryan Chow said the token is a way to link Bitcoin to “real-world economic cycles” in uncorrelated assets such as US government bonds and private credit, as opposed to BTC’s typical boom-and-bust four-year cycle.

The token uses a multi-protocol strategy to generate yield involving Elixir’s deUSD stablecoin, Treasurys provided by BlackRock and Hamilton Lane via Elixir, and incorporated on the lending platform Euler to increase RWA exposure.

Key takeaways:

The total altcoin market cap (excluding ETH) gained $126 billion in Q2, fueling speculation of an altseason.

The altcoin market cap, excluding Ether (ETH), has added $126 billion in Q2, sparking enthusiasm from analysts who have been waiting for an altseason. Crypto analyst Javon Marks noted a breakout that could rival the explosive 2017 bull run. 

In a recent post on X, Marks highlighted a chart comparing the TOTAL3 index (total market cap of altcoins excluding Bitcoin (BTC) and Ethereum) against the US money supply, suggesting that altcoins may be on the verge of a significant rally. 

A rise in TOTAL3 against the US money supply suggests that altcoins are gaining value relative to the total liquidity in the US economy, reflecting increased investor interest and capital inflow into altcoins. 

Galaxy Digital shares began trading on the Nasdaq stock exchange May 16, completing a years-long process that CEO Mike Novogratz called unfair and infuriating, CNBC reported.

The crypto and infrastructure company, which is also listed in Canada, opened trading at $23.50 in its Nasdaq debut.

Trading began on the same day Galaxy disclosed that it is working with the US Securities and Exchange Commission (SEC) to tokenize its shares. According to Bloomberg, the tokens representing Galaxy Digital’s shares could be used in decentralized finance applications, like borrowing or lending.

Galaxy is among several crypto companies looking to access the US markets under a friendlier regulatory regime in the country. Companies that are also exploring or working on a US listing include Metaplanet, Circle, Kraken, and Gemini. Trading platform eToro completed a listing on May 14.

The company has $7 billion in assets on its platform, according to its website. It suffered a loss of $295 million in the first quarter of 2025.

Key takeaways:

Bitfinex margin longs fell 18%, despite Bitcoin price rising 24% in 30 days.

$6.8 billion in long positions far outweight the current $25 million in shorts.

Bitcoin options positioning and spot BTC inflows point to confidence from institutional investors.

Bitcoin (BTC) price climbed 23.7% over the past 30 days, yet traders on Bitfinex have cut their leveraged long positions by more than 18,000 BTC during this time. This wave of profit-taking in margin markets has led to speculation that professional traders may not be fully confident in the current $104,000 price level.

Zach Witkoff, one of the co-founders of the Donald Trump family-backed crypto platform World Liberty Financial (WLFI), has rebuffed efforts by US lawmakers to investigate the president’s potential conflicts of interest.

In a May 15 letter to Senator Richard Blumenthal, lawyers for World Liberty Financial claimed a call to investigate the crypto platform was based on “fundamentally flawed premises and inaccuracies.” Witkoff did not specifically address any allegations, claiming that WLFI was “too busy building” for oversight.

“The Company rejects the false choice between innovation and oversight,” said the letter. “What it opposes is the misuses of regulatory authority and uncertainty to suppress lawful innovation.”

Blumenthal, the ranking member of the US Senate Permanent Subcommittee on Investigations, was one of many Democrats calling for investigations and legislative changes in response to Trump’s ties to WLFI, as well as his TRUMP memecoin and its dinner scheduled for the top tokenholders on May 22.

The GENIUS Act, a bill to recognize stablecoins as payment instruments currently being considered in Congress, may be a bellwether for how lawmakers intend to handle the president’s potential conflicts of interest.

A federal judge sentenced Eric Council Jr., who participated in posting a fake announcement on the US Securities and Exchange Commission’s X account saying it would approve spot Bitcoin (BTC) ETFs, to 14 months in prison.

Following a May 16 hearing in the US District Court for the District of Columbia, the Justice Department announced that Council would serve 14 months in prison after pleading guilty to one count of conspiracy to commit aggravated identity theft and access device fraud.

“Schemes of this nature threaten the health and integrity of our market system,” said Jeanine Pirro, interim US Attorney for the District of Columbia. “SIM swap schemes threaten the financial security of average citizens, financial institutions, and government agencies.”

Council was part of a group that compromised the X account of the US Securities and Exchange Commission (SEC) through a SIM swap attack in January 2024. Prosecutors had requested that the judge impose a two-year sentence, while Council’s lawyers asked for one year and one day. Court filings showed he earned roughly $50,000 through SIM swap attacks like the one that compromised the SEC’s X account — funds likely subject to forfeiture.

Christy Goldsmith Romero of the US Commodity Futures Trading Commission (CFTC) will step down on May 31, leaving three seats open at the financial regulator.

In a May 16 announcement, Romero said her last day at the agency would be on May 31, ahead of her reported initial plans to leave if the Senate confirmed former commissioner Brian Quintenz as the new chair. Her departure will come a day after Commissioner Summer Mersinger is expected to step down to join the crypto advocacy organization the Blockchain Association as CEO.

“It has been a tremendous honor to conclude my 23 years of federal service at an agency with such an important mission to ensure that financial markets perform their critical role in the US and global economies,” said Romero.

Romero and Mersinger’s upcoming departures would leave the CFTC with only two Senate-confirmed members: acting chair Caroline Pham and Commissioner Kristin Johnson, each taking one Republican and Democratic seat, respectively. However, Pham also announced that she planned to leave after Quintenz’s confirmation. The shakeup in leadership potentially gives President Donald Trump the opportunity to pick three more commissioners after the Senate addresses Quintenz’s nomination.

Shares of Basel Medical Group are down around 15% after the healthcare company announced plans to buy $1 billion in Bitcoin for its corporate treasury. 

On May 16, Singapore-based Basel said it was “in advanced discussions with a consortium of institutional investors and high-net-worth individuals […] to acquire a US$1 billion BTC through an innovative share-swap arrangement.

The company said the benefits of its planned purchase include creating “one of the strongest balance sheets among Asia-focused healthcare providers” and providing “unmatched financial flexibility for mergers and acquisitions.”

It also said the Bitcoin (BTC) treasury would help Basel “[e]stablish “a diversified asset base to weather market volatility.”

But the company’s shareholders weren’t sold. Basel’s stock, BMGL, has dropped around 15% on the announcement, according to data from Google Finance.

Key points:

A Bitcoin price close above $105,000 could accelerate momentum and trigger a rally to $130,000.

Ether continues to gain strength, which is being mirrored by many altcoins.

Bitcoin (BTC) has been consolidating between $100,718 and $105,819 for the past few days, indicating a balance between supply and demand. A positive sign is that the price has held above the psychologically crucial $100,000 level, signaling that the bulls are hanging on to their positions as they anticipate another leg higher.

Market intelligence firm Santiment highlighted in a post on X that the failure to rise above $105,000 has caused impatience among retail traders, which “historically is a bullish sign for prices.”

Shares of AI cloud computing company CoreWeave (CRWV) surged on May 16 after chip giant Nvidia revealed a large ownership stake, signaling growing corporate and institutional interest in the newly public company.

CRWV stock climbed as much as 26.3% in New York trading, pushing its market capitalization above $38 billion. Trading volumes were more than double the daily average, according to Yahoo Finance data.

The stock was last seen trading around $81, up 23% on the day.

CoreWeave’s rally was sparked by regulatory filings from Nvidia showing that the company owned $900 million of CRWV stock at the end of the first quarter. The value of the holdings has more than doubled since March 31, assuming Nvidia hasn’t sold any shares since then.

As CNBC reported, Nvidia’s ownership stake at the time of CoreWeave’s initial public offering (IPO) was 17.9 million shares.

News broke on May 15 that Coinbase was the target of a $20 million extortion attempt after cybercriminals recruited overseas support agents to leak user data for social engineering scams.

While less than 1% of Coinbase’s active monthly users were reportedly affected, the expected remediation and reimbursement expenses range from $180 million to $400 million, as the exchange pledged to repay all phishing attack victims.

Despite the attack on the world’s third-largest cryptocurrency exchange, investor sentiment remains optimistic, with the Fear & Greed Index remaining firmly in the “Greed” zone above 69, according to CoinMarketCap data.
