Australian Senator Gerard Rennick has drawn criticism from the Bitcoin community following his remarks referring to Bitcoin as a Ponzi scheme and questioning the asset’s value because it can’t be eaten.

“You can’t eat Bitcoin,” Rennick said in a May 23 X post, responding to an X user who questioned his stance after Bitcoin hit a new all-time high of $111,970 on May 22.

Rennick says Bitcoin will go to $1 million but is a “Ponzi Scheme”

“Bitcoin will ultimately go to $1 million dollars. Why, because it’s a Ponzi scheme whereby BlackRock will pump more and more dollars into a supply-constrained product,” Rennick said.

“What exactly will this product produce?” Rennick said. He added that Bitcoin (BTC) will produce “absolutely nothing” and Australia “needs real engineers not financial engineers.”

Bitcoiners across the world were quick to respond to Rennick’s comments. The Australian Bitcoin Industry Body (ABIB) said Rennick’s remarks about “Bitcoin reveal a deep misunderstanding.” The ABIB added:

“This matters, because misunderstanding leads to misrepresentation. And misrepresentation leads to bad policy.”

Unchained podcast host Laura Shin said, “You also can’t eat the internet, so do you oppose that too?” Bitcoin Marathon team lead Jimmy Kostro said, “This is definitely going to age well. Please enlighten us with more of your deep and nuanced understanding of Bitcoin.”

Rennick responded to the criticism and said he doesn’t “need to explain anything.”

“It’s pathetic how the Bitcoin community needs reassurance from a politician – the very people they claim they want to be free from,” Rennick said.

The Bitcoin community has frequently spoken out when prominent individuals have expressed anti-Bitcoin views.

Only a few weeks ago, Arizona Governor Katie Hobbs experienced backlash from the Bitcoin community after her decision to veto a bill that would have allowed the state to hold Bitcoin as part of its official reserves.

Casa co-founder and cypherpunk Jameson Lopp said, “This will age poorly.” Meanwhile, Bitcoin entrepreneur Anthony Pompliano said, “Imagine the ignorance of a politician to believe they can make investment decisions.” Crypto lawyer Andrew Gordon said, “We need more elected officials who understand that Bitcoin and crypto are the future.”

The Bitcoin community also pushed back when the US government decided to transfer $1.9 billion of Bitcoin to Coinbase in December 2024.

ARK Invest CEO Cathie Wood says crypto exchange-traded funds (ETFs) will likely maintain their place in the economy, regardless of how widespread crypto wallet adoption becomes over the next decade.

“I think ETFs are an important stepping stone because, you know, wallets seem so complicated, so much friction for consumers, they just wanna push a button,” Wood said at the Solana Accelerate event in New York on May 23.

Wallets remain an insurance policy, says Wood

“So ETFs for those who want the convenience, I don’t think, will lose a lot of their luster,” she said. “But they will be a stepping stone into wallet-based.” Wood reiterated the extra layer of protection that crypto wallets provide:

“These are insurance policies against something going wrong in the traditional world.”

Bitbo data suggests that there are around 200 million active Bitcoin (BTC) wallets worldwide. Meanwhile, the trading week ending May 23 saw approximately $2.75 billion inflows into US-based spot Bitcoin ETFs, coinciding with Bitcoin reaching a new all-time high of $111,970 on May 22.

Since spot Bitcoin ETFs launched in the US in January 2024, approximately $44.49 billion in inflows have been recorded, according to Farside data. Meanwhile, spot Ether (ETH) ETFs have seen approximately $2.77 billion in inflows since launching in July 2024.

Wood said that spot Ether ETFs were “less successful than people were expecting” because the US Securities and Exchange Commission did not allow staking. On May 21, the SEC delayed its decision on Bitwise’s application to add staking to its Ether exchange-traded fund.

However, Wood still views Ether as the entry point for new investors to familiarize themselves with smart contracts before exploring other cryptocurrencies, such as Solana (SOL).

“So they might start in the smart contract world with Ether, but once they study the technology, and follow the developers, and see the uptake by consumers, I think they will get there,” Wood said.

Wood said that the launch of US President Donald Trump’s memecoin, Official Trump (TRUMP), in January on the Solana network may have caused investors to be skeptical of Solana.

“Institutions and you’re saying 60-year-olds…I think they might be a little turned off by what happened with the Trump memecoin,” Wood said. Just days after its launch on Jan. 17, TRUMP slid around 50% after the president made no crypto-related “day one” executive orders.

“I mean, that might scare them,” Wood said. Her comments came in response to ETF analyst Eric Balchunas reiterating the point that Bitcoin is “so easy” to explain to a “boomer or adviser” as being digital gold, but other cryptocurrencies “are tougher.”

Wood said she is still finalizing her Solana price target and will share it once her research is complete.

In April, ARK raised its “bull case” Bitcoin price target from $1.5 million to $2.4 million by the end of 2030, primarily driven by institutional investors and Bitcoin’s increasing acceptance as “digital gold.”

Telegram co-founder Pavel Durov will not be physically attending the Oslo Freedom Forum in Oslo, Norway, after French courts denied his request to travel to the Scandinavian country.

According to an announcement from the Human Rights Foundation (HRF) — a non-profit organization that advocates for universal human rights and individual liberty, and the host of the Oslo Freedom Forum — Durov will still deliver his keynote address remotely over a livestream.

“It is unfortunate that French courts would block Mr. Durov from participating in an event where his voice is so needed,” HRF founder and CEO Thor Halvorssen said.

Durov continues to be a vocal advocate for free speech and individual liberty. Tech and crypto industry executives closely monitor developments related to Pavel Durov and the implications for individual freedom from his ongoing legal battle in France.

Durov claims French intelligence services asked him to censor conservative voices

Pavel Durov recently accused French intelligence officials of asking him to censor conservative-leaning political content related to the Romanian presidential elections on the Telegram platform.

Durov said that he flatly denied the request. “You can’t ‘defend democracy’ by destroying democracy. You can’t ‘fight election interference’ by interfering with elections,” Durov wrote in a May 18 Telegram post.

Although the Telegram founder did not initially name the intelligence official or the European Union country that asked him to censor the content, Durov later revealed more concrete details. The Telegram co-founder wrote in a May 18 X post:

“This spring at the Salon des Batailles, in the Hôtel de Crillon, Nicolas Lerner, head of French intelligence, asked me to ban conservative voices in Romania ahead of elections. I refused. We didn’t block protesters in Russia, Belarus, or Iran. We won’t start doing it in Europe.”

Durov has repeatedly stated that Telegram will not censor political content on the platform and would exit markets before restricting free speech on the social messaging application.

The Telegram co-founder said that complying with such heavy-handed political censorship constitutes a human rights violation.

Scammers posing as Ledger, a hardware wallet manufacturer, are sending physical letters to crypto users instructing them to “validate” their wallets or risk losing access to funds, in the latest phishing attack to impact the industry.

BitGo CEO Mike Belshe shared a picture of the scam letter, which featured a QR code, presumably linked to a malicious phishing site. The letter was sent through the United States Postal Service (USPS), according to the executive.

“These are all scams do not fall for any of these,” Troy Lindsey wrote after receiving a copy of the phishing letter.

Cointelegraph reached out to Ledger for comment but was unable to obtain a response by the time of publication.

This phishing attempt highlights the ever-evolving complexity and tactics of social engineering scams designed to steal crypto private keys, user funds, and other sensitive data from unsuspecting victims.

Coinbase and crypto users hit hard by phishing attacks in 2025

In April 2025, $330 million in Bitcoin (BTC) was stolen from an elderly individual through a phishing attack, onchain detective ZackXBT confirmed in an April 30 X post.

“Two suspects in the $330 million heist include ‘Nina/Mo’ — a Somalian who operates a call scam center in Camden, UK — and an accomplice ‘W0rk,’ who assisted with the site and call,” the onchain security analyst said in an update.

On May 15, crypto exchange Coinbase announced it was the target of a ransom attempt after customer service contractors, who were later fired by the company, leaked user data to threat actors.

The scammers demanded a $20 million ransom, which Coinbase refused to pay, and the stolen data included names, addresses, contact information, and a limited amount of other sensitive account data belonging to a small subset of Coinbase customers.

No private keys, login credentials, or accesses to Coinbase Prime accounts were compromised during the leak, according to the exchange.

TechCrunch founder Michael Arrington was highly critical of the exchange for the security failure, arguing that it will lead to physical violence against customers exposed in the hack.

Decentralizing telecommunication networks financially benefits small businesses and telecom corporations alike, according to Frank Mong, the chief operating officer (COO) of Nova Labs, the founding team behind the Helium wireless decentralized physical infrastructure (DePIN) network.

In an interview with Cointelegraph at Consensus 2025 in Toronto, Canada, Mong said that small businesses including bars, restaurants, convenience stores, and other local operators can generate revenue by hosting wireless hotspots and expanding network coverage.

Large telecommunication companies and service providers can also tap into the Helium Network’s telemetry to reduce operational costs and expand network coverage in dead zones.

“It costs about $300,000 for a telecom company to stand up one tower; you need one per block for 5G to work effectively,” Mong told Cointelegraph, The executive added:

“Instead of doing that and making phone plans more expensive, what if anyone with a useful Wi-Fi network shares that Wi-Fi and allows, not just anyone to use it securely, but allows large companies like AT&T to see the telemetry of that network.”

Decentralized physical infrastructure networks continue to be an example of how blockchain technologies can provide real-world value and make existing infrastructure more resilient to outages, disruptions, censorship, and critical failure.

Helium secures collaborative partnerships with telecom companies

In January 2024, Nova Labs announced a collaborative partnership with Latin American telecommunication company Telefónica to expand the telecom company’s coverage in dead zones and help reduce network congestion.

More recently, in April 2025, Helium partnered with AT&T — a global telecommunication giant — to allow AT&T users automatic access to the Helium Network when in range of the network’s coverage area of mobile hotspots.

Data from the Helium Network shows that the United States currently has the highest concentration of the network’s 95,272 mobile hotspots. Additionally, Helium has 284,053 active Internet of Things (IoT) hotspots worldwide.

Well-known Hyperliquid trader James Wynn has increased his 40x leverage long Bitcoin bet to $1.25 billion after closing his PEPE position for a $25.2 million profit.

On May 24, Lookonchain reported that Wynn entered an 11,588 BTC position with an average entry price of $108,243 and a liquidation level of $105,180.

The move came hours after Wynn exited his Ether (ETH) and Sui (SUI) longs at a $5.3 million loss. At the time, he used the proceedings to double down on Bitcoin (BTC), increasing his position to 11,070 BTC.

Wynn began his Bitcoin long position with $830 million on May 21, trimming $400 million in profits the same day. By May 22, he ramped the position back up to $1.1 billion, holding high leverage as BTC crossed $110,000 and gained $39 million on paper. He later sold 540 BTC for $60 million, securing a $1.5 million profit.

Wynn suffers losses after Trump tariff threat

Wynn took a hit following a sharp market downturn triggered by former President Donald Trump’s announcement of a 50% tariff on all European Union imports.

The news, delivered on May 23, sent Bitcoin tumbling below $107,000 and erased gains across both traditional and crypto markets. Ether also dropped to as low as $2,504 while memecoins were hit even harder.

Data from HypurrScan shows that Wynn has suffered more than $29 million in losses over the past day alone. However, he is still up more than $57 million in all-time trading and $46 million over the past month alone.

High-stakes crypto trader

Wynn is a high-stakes crypto trader who describes himself as a high-risk leverage trader and memecoin maxi. He also claims to have called Pepe (PEPE) a buy when its market cap was at $600,000.

The crypto whale started using Hyperliquid two months ago, depositing $4.65 million worth of the stablecoin USDC (USDC) onto the platform, Hypurrscan data shows.

Hyperliquid’s DEX is the flagship product on the Hyperliquid layer-1 blockchain, which also offers spot trading and borrowing and lending services, among other things.

Notably, Wynn’s aggressive leverage amplifies his exposure to volatility. With Bitcoin trading near $109,000, any sharp move downward could threaten the position.

President Donald Trump is facing scrutiny after speaking at a private event for top investors in his $TRUMP memecoin while standing behind a lectern emblazoned with the official presidential seal — a move that may violate federal law.

The event took place Thursday at Trump National Golf Club in Virginia, where Trump addressed 220 investors in his cryptocurrency project.

According to US law, the presidential seal cannot be used in any manner that could imply government approval or sponsorship. Violators can face fines or up to six months in prison.

Trump, who arrived at the club aboard a military helicopter, praised attendees and took aim at the Biden administration’s crypto stance.

When asked about potential conflicts of interest, White House Press Secretary Karoline Leavitt said the president’s involvement was personal. “It is not a White House dinner,” she told reporters. “It’s not taking place here at the White House.”

Trump features presidential seal at private properties

This isn’t the first time Trump has featured the presidential seal at his private properties. Forbes has previously reported its use as golf markers at several Trump-owned clubs.

In a May 22 letter to the Justice Department, 35 House members asked the public integrity section acting chief, Edward Sullivan, to launch an inquiry over the memecoin dinner to determine whether it violated the federal bribery statute or the foreign emoluments clause of the US Constitution. 

Under the emoluments clause, a US president is barred from accepting any gift from a foreign state without the approval of Congress.

Bloomberg reported that a majority of the attendees at the memecoin dinner were likely foreign nationals based on their connections to crypto exchanges. 

“US law prohibits foreign persons from contributing to US political campaigns,” said the letter. “However, the $TRUMP memecoin, including the promotion of a dinner promising exclusive access to the President, opens the door for foreign governments to buy influence with the President, all without disclosing their identities.”

Trump embraces crypto despite previous skepticism

Trump’s embrace of crypto marks a sharp turn from his skepticism during his first term. The $TRUMP memecoin, launched earlier this year, peaked at $74.34 before falling to $14.44 by May 22.

High-profile guests at the dinner included Tron founder Justin Sun, ex-NBA player Lamar Odom, and Asian crypto executives Sangrok Oh and Vincent Liu.

Sun, who reportedly invested over $40 million in $TRUMP tokens and spoke at the dinner, also has deep ties to Trump’s crypto ventures. He’s the top backer of World Liberty Financial, a Trump-affiliated firm currently under regulatory scrutiny.

A US federal judge has vacated key fraud and manipulation convictions against Avraham Eisenberg, the trader at the center of the case involving a $110 million exploit of the decentralized exchange Mango Markets.

On Friday, US District Judge Arun Subramanian ruled that the evidence presented at trial failed to support the jury’s conclusion that Eisenberg made materially false representations to Mango Markets.

The decision vacates Eisenberg’s convictions for commodities fraud and market manipulation and acquits him of a third charge, significantly weakening the government’s case.

Eisenberg, a self-proclaimed “applied game theorist,” was convicted in 2024 for artificially inflating the price of Mango’s MNGO token by over 1,300% in a matter of minutes and using the resulting gains as collateral to withdraw $110 million in crypto assets from the platform.

Judge sides with Eisenberg

The Justice Department argued that he deceived Mango’s smart contract-based lending system, but Eisenberg’s defense maintained that he merely exploited poorly designed, permissionless code — without making any false representations.

Judge Subramanian agreed, writing that “Mango Markets was permissionless and automatic,” meaning the system couldn’t be deceived in a legal sense. “There was insufficient evidence of falsity,” the judge added, siding with Eisenberg’s interpretation of DeFi mechanics.

The judge also rejected prosecutors’ argument that the case should be heard in New York. Eisenberg was in Puerto Rico at the time of the trades, and the court found that no meaningful activity tied to the alleged crime occurred in New York.

The DOJ had cited a Poughkeepsie-based Mango user and a third-party vendor in Manhattan, but the judge ruled these were not enough to establish proper venue.

The US government must now decide whether to refile the vacated charges, though the Trump administration has recently signaled a reduced focus on crypto enforcement. Eisenberg still faces civil suits from both the SEC and CFTC.

While this ruling clears Eisenberg in the Mango Markets case, he remains behind bars.

Eisenberg charged with child pornography

In a separate case, Eisenberg was sentenced to nearly four years in prison on May 1 after pleading guilty to possessing child pornography — a charge stemming from unrelated evidence uncovered during his arrest.

In December 2022, US federal law enforcement authorities arrested Eisenberg in Puerto Rico. FBI officials charged the hacker with one count of commodities fraud and one count of commodities manipulation.

A jury found Eisenberg guilty of wire fraud, commodities fraud, and commodities manipulation in April 2024. The defense argued that the exploit was not a cybercrime and represented a “successful and legal trading strategy.”
