Coinbase breach hit almost 70k users — Attorneys

A recent filing with Maine’s attorney general sheds new light on Coinbase’s data breach, claiming that nearly 70,000 users were impacted and that the incident went unnoticed for nearly six months.

According to the filing submitted by legal firm Latham and Watkins LLP, 69,461Coinbase users were compromised by the breach, 217 of whom are residents of the US state of Maine.

The document also indicates the breach occurred on Dec. 26, 2024, but was only discovered on May 11, 2025 — nearly six months following the cybersecurity incident.

Coinbase now faces a flurry of lawsuits from affected clients, who argue that the exchange failed to notify victims of the security breach in a timely manner. The attack caused $400 million in losses through social engineering scams and remediation costs, Coinbase has said.

Cointelegraph contacted Coinbase for comment, but had not received a response at time of publication.

Interest groups, lawmakers to protest Trump's memecoin dinner

Democratic leaning organizations and members of Congress have announced plans to protest what they describe as the sale of access to the office of the US president, in reference to Donald Trump’s memecoin dinner on May 22. The event’s attendees are said to have collectively spent over $100 million for the chance to meet with the US president.

Since Trump’s memecoin project, Official Trump (TRUMP), announced that its top 220 tokenholders would have an opportunity to apply for an exclusive dinner with the president, many leaders in the crypto industry and US lawmakers have criticized the event, saying Trump was opening his office to potential bribery and corruption.

The memecoin dinner prompted some Democratic lawmakers to withdraw support for crypto-related legislation in Congress, including the market structure and stablecoin bills.

“Trump collecting gifts from foreign governments is unconstitutional,” a spokesperson for the consumer advocacy organization Public

Texas House passes strategic Bitcoin reserve bill

The Texas House of Representatives has passed the third reading of SB 21, a bill that seeks to establish a strategic Bitcoin reserve in the state. The bill passed in a 101-42 vote and will now go to Texas Governor Greg Abbott to either sign into law or veto.

SB 21, authored by state Senator Charles Schwertner, establishes a Bitcoin (BTC) reserve that is managed by the state’s comptroller. The legislation allows the comptroller to invest in any cryptocurrency with a market cap above $500 billion over the previous 12-month period. Currently, the only cryptocurrency fitting the requirement is Bitcoin.

Is Bitcoin price close to a cycle top? — 5 indicators that help traders decide

Key takeaways:

Bitcoin market cycle tops are notoriously hard to time, but combining technical and behavioral indicators can offer strong signals.

The MVRV-Z Score, Pi Cycle Top indicator, trade volume trends, Puell Multiple, and exchange inflows accurately predict Bitcoin price cycle tops.

Bitcoin (BTC) might be approaching the final stage of its current market cycle — a dramatic final rally followed by a sharp correction and, eventually, a bear market. For many, this could be the long-awaited climax of the past four years, and major players are preparing accordingly.

Since late 2024, Bitcoin whale accumulation has surged. Glassnode data shows that the number of addresses holding over 100 BTC has jumped by almost 14%, reaching 18,200 — a level not seen since 2017. The biggest market players appear to be positioning for what could be this cycle’s final run-up.

Bank lobby is 'panicking' about yield-bearing stablecoins — NYU professor

America’s powerful banking lobby is “panicking” over the potential of stablecoins to disrupt their traditional business model, particularly when it comes to yield-bearing stablecoins, according to Austin Campbell, a New York University professor and founder of Zero Knowledge Consulting.

In a May 21 social media post that begins with, “The Empire Lobbies Back,” Campbell claimed that the banking industry is especially alarmed by the potential for stablecoins to offer interest or rewards to holders. 

In a pointed message aimed at Democratic lawmakers, Campbell wrote that “banks want you to protect their cartel so they can keep screwing your voters.”

He went on to explain how fractional reserve banking enables banks to maximize profits while offering depositors minimal interest.

The banking lobby says that if stablecoins pay interest or any other type of monetary reward, banks will be “harmed,” Campbell added.

Bitcoin enters ‘acceleration phase’ resembling BTC price gains seen after Trump election victory

Key takeaways:

The Bitcoin Quantile Model shows “heat” with price on the verge of an “acceleration phase,” echoing Q4 2024 when BTC embarked on a 45% post-election rally.

Bitcoin (BTC) price has formed a new intraday high on each daily candle this week, with the crypto asset slowly grinding toward a new all-time high. In line with its current trajectory, 21st Capital co-founder Sina noted that Bitcoin is approaching a pivotal moment around the $108,000 level. 

The Bitcoin Quantile Model update shows that BTC’s market reflects the same “heat” that was present after President Trump’s post-election rally and the spot ETF-driven highs during Q4 2024. The model, which uses quantile regression to map Bitcoin’s price phases on a logarithmic scale, indicates the cryptocurrency is in the Transition Zone, a critical juncture before the Acceleration Phase. Throughout Q4, 2024, Bitcoin rallied by 45% after entering a price discovery period above

Bitcoin hits new all-time high of $109K as trade war tensions ease

Bitcoin surged to a new all-time high after a temporary trade agreement between the United States and China eased macroeconomic fears and boosted investor confidence.

Bitcoin (BTC) set a new high of $109,400 on May 21, rising more than 26% in the past month, according to data from TradingView. This climb to a record high came nine days after the White House announced a 90-day trade agreement between the US and China on May 12, temporarily slashing import tariffs to 10%.

The 90-day tariff suspension and the cooperative tone in negotiations removed the risk of “sudden re-escalation,” which had a significant impact on risk appetite among traditional and cryptocurrency investors, Aurelie Barthere, principal research analyst at crypto intelligence platform Nansen, told Cointelegraph.

US President Donald Trump’s reciprocal tariffs were seen as the biggest macroeconomic threat to traditional equities and

Crypto's real momentum isn't in the charts; it's in developer activity

Opinion by: Markus Levin, co-founder of XYO

The crypto community often experiences periods of heightened anxiety. Market downturns are often triggered by counterproductive sentiment-driven events rather than by fundamental issues, creating a significant disconnect between price behavior and the actual progress being made within the industry by the companies within it. What often goes unnoticed is how much real development happens during these downturns. While market movements capture most of the attention, teams are building faster and more deliberately behind the scenes than ever. The focus shifts away from price speculation and toward real execution. Growth happens during downturns. It’s a necessary phase for projects that thrive in a volatile industry. They re-focus attention on refining their technology and business, fueling the next wave of progress.

As a result, there’s a disconnect between online sentiment and conversations between blockchain industry leaders. For builders and project leaders, the atmosphere is of determination, not
