Bitcoin breaks out while Coinbase breaks down: Finance Redefined
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.
Adding to investor optimism, Coinbase saw over $1 billion worth of Bitcoin withdrawn on May 9, marking the highest net outflow recorded in 2025 so far, triggering analyst predictions of a supply-shock driven Bitcoin rally.
Coinbase faces $400 million bill after insider phishing attack
Coinbase was hit by a $20 million extortion attempt after cybercriminals recruited overseas support agents to leak user data, the company said on May 15.
Coinbase said a group of external actors bribed and coordinated with several customer support contractors to access internal systems and steal limited user account data.
“These insiders abused their access to customer support systems to steal the account data for a small subset of customers,” Coinbase said, adding that no passwords, private keys, funds or Coinbase Prime accounts were affected.
Less than 1% of Coinbase’s monthly transacting users’ data was affected by the attack, the company said.
After stealing the data, the attackers attempted to extort $20 million worth of Bitcoin (BTC) from Coinbase in exchange for not disclosing the breach. Coinbase refused the demand.
Instead, the company offered a $20 million reward for information leading to the arrest and conviction of those responsible for the scheme.
$1 billion Bitcoin exits Coinbase in a day as analysts warn of supply shock
Institutional demand for Bitcoin is growing, as Coinbase, the world’s third-largest cryptocurrency exchange, recorded its highest daily outflows of Bitcoin in 2025 on May 9.
On May 9, Coinbase saw 9,739 Bitcoin, worth more than $1 billion, withdrawn from the exchange, the highest net outflow recorded in 2025, according to Bitwise head of European research André Dragosch.
“Institutional appetite for Bitcoin is accelerating,” Dragosch added in a May 13 X post.
The outflow occurred as Bitcoin traded above $103,600 and just days after the White House announced a 90-day reduction in reciprocal tariffs between the US and China, easing market concerns and lifting broader investor sentiment.
The 90-day suspension of additional tariffs removed the risk of “sudden re-escalation,” which may help Bitcoin, altcoins and the wider stock market rally due to improved risk appetite, Nansen’s principal research analyst, Aurelie Barthere, told Cointelegraph.
DeFi lender Aave reaches $40 billion in value locked onchain
Aave, a decentralized finance (DeFi) protocol, has reached a new record of funds onchain, according to data from DefiLlama.
In an X post, Aave said it topped $40.3 billion in total value locked (TVL) on May 12. Onchain data reveals that Aave v3, the latest version of the protocol, has about $40 billion in TVL.
Aave is a DeFi lending protocol that lets users borrow cryptocurrency by depositing other types of cryptocurrency as collateral. Meanwhile, lenders earn yield from borrowers.
“With these milestones, Aave is proving its dominance in the Lending Space,” DeFi analyst Jonaso said in a May 12 X post. TVL represents the total value of cryptocurrency deposited into a protocol’s smart contracts.
SEC delays Solana ETF as decisions for Polkadot, XRP loom
The US Securities and Exchange Commission (SEC) pushed back its decision on a proposed spot Solana exchange-traded fund (ETF), with the cryptocurrency industry now looking to the deadlines for the Polkadot and XRP-based ETFs in June.
The SEC delayed its decision on listing Grayscale’s spot Solana (SOL) Trust ETF on the New York Stock Exchange (NYSE) to October 2025, according to a May 13 filing by the securities regulator.
The decision came the week after the SEC delayed its ruling on Canary Capital’s Litecoin (LTC) ETF, Bloomberg Intelligence analyst James Seyffart wrote in a May 5 X post.
Spot ETFs are key drivers of liquidity and institutional adoption for digital assets. For Bitcoin, the US spot Bitcoin ETFs accounted for an estimated 75% of new investment after launching, which helped BTC recapture the $50,000 mark in February 2024, a month after the ETFs debuted for trading.
While a Solana ETF may generate only a fraction of the inflows of Bitcoin ETFs, it could increase Solana’s institutional adoption in the long term by offering investors a “regulated investment vehicle” that may still attract billions of dollars in capital, Ryan Lee, chief analyst at Bitget Research, told Cointelegraph.
Starknet hits “Stage 1” decentralization, tops ZK-rollups for value locked
Ethereum layer-2 scaling platform Starknet has reached a decentralization milestone laid out by Ethereum co-founder Vitalik Buterin and is now the largest zero-knowledge rollup-based network by total value locked.
Starknet said in a news release shared with Cointelegraph that it has hit “Stage 1” decentralization, according to a framework Buterin laid out in 2022, which means the network operates with limited oversight or “training wheels.”
Starknet added that the framework was the “gold standard onchain tool for analyzing Ethereum scaling solutions,” and said it achieved the milestone through changes such as creating a security council and censorship-avoidance mechanisms.
While the system still allows intervention from a security council, it has implemented a fully functional validity proof system governed by smart contracts.
Starknet is now the only layer-2 ZK-rollup network to have reached Stage 1 and has grown to be the largest ZK-rollup blockchain with a total value locked of $629 million, just ahead of ZKsync’s $610 million, according to L2beat.
Starknet is the fifth-largest layer-2 network by value locked, with the top four all Optimistic rollup-based, having reached Stage 1 decentralization using fraud proofs.

Chief rabbi condemns BBC’s ‘mishandled response’ to anti-IDF chanting at Glastonbury – as Bob Vylan issue new statement
The chief rabbi has described the BBC’s response to anti-IDF chanting at Glastonbury as “belated and mishandled” – as the punk-rap duo involved, Bob Vylan, said the UK government needed to talk about its “criminal inaction”.
Sir Ephraim Mirvis said “vile Jew-hatred” had been aired at the Somerset music festival and it was a “time of national shame”.
Confidence in the BBC’s “ability to treat antisemitism seriously” has been brought to a “new low”, he said in a post on X, adding that “outright incitement to violence and hatred” appeared to be acceptable if it was couched as “edgy political commentary”.
Ordinary people had not only failed to see incitement “for what it is” but had cheered it, chanted it, and celebrated it, he said. “Toxic Jew-hatred is a threat to our entire society,” he added.
Bob Vylan, posting a new statement on Instagram on Tuesday, said they were “not for the death of Jews, Arabs or any other race or group of people”.
Rather, they were for the “dismantling of a violent military machine” – the Israel Defence Forces.
Bob Vylan chanted “death to the IDF” at Glastonbury. As many as 95% of the IDF are thought to be Jewish.
In their statement, the group said they were a “distraction from the story” and that whatever “sanctions” they received would also be a distraction.
Their US visas have been revoked and United Talent Agency, their US representatives, have dropped them.

Referring to the war in Gaza, they claimed the UK government does not want them to ask “why they remain silent in the face of this atrocity”, “why they aren’t doing more to stop the killing” and “feed the starving”.
They added: “The more time they talk about Bob Vylan, the less time they spend answering for their criminal inaction.
“We are being targeted for speaking up. We are not the first, we will not be the last, and if you care for the sanctity of human life and freedom of speech, we urge you to speak up, too.”
It has emerged that Tim Davie, the BBC’s director-general, was at Glastonbury when the duo led chants of “Death to the IDF” which were broadcast live.
The prime minister’s spokesman, asked if the PM had confidence in Mr Davie, said Sir Keir Starmer had “confidence in the BBC”, adding: “The position of the director-general is a matter for the BBC’s board.”
Speaking in the Commons, Culture Secretary Lisa Nandy said “accountability” was important and it was something she had “impressed upon the BBC leadership”.
She added: “When you have one editorial failure, it’s something that must be gripped. When you have several, it becomes a problem of leadership.”
The cabinet minister said she’d called Mr Davie after Bob Vylan’s set had been broadcast to find out why it had aired, and why the feed had not been cut.
“I expect answers to these questions without delay,” she said.
Meanwhile Dame Caroline Dinenage, chair of the culture, media and sport committee, has written to Mr Davie in relation to the corporation’s Glastonbury coverage.
The committee has said the letter asks about editorial and decision-making processes and whether consideration was given to broadcasting with a delay. It also asks about staffing levels at the festival and contingency planning.

Avon and Somerset Police has begun a criminal investigation and is reviewing footage of both Bob Vylan and Kneecap’s performances at Glastonbury.
The force said a senior detective had been appointed – and it had been contacted by people from around the world.
“We… recognise the strength of public feeling,” it said.
During Kneecap’s set, one member suggested starting a “riot” outside his bandmate’s forthcoming court appearance, before clarifying that he meant “support”. Liam Og O hAnnaidh, also known as Mo Chara, is charged with a terror offence.

Bob Vylan had been due to tour the US before their visas were revoked.
US deputy secretary of state Christopher Landau said action had been taken “in light of their hateful tirade at Glastonbury, including leading the crowd in death chants”.
“Foreigners who glorify violence and hatred are not welcome visitors to our country,” he added.

During Bob Vylan’s set, the duo performed in front of a screen that showed several messages, including one that claimed Israel’s actions in Gaza amounted to “genocide”.
The war in Gaza began after Hamas militants attacked Israel on 7 October 2023 and killed 1,200 people and took about 250 hostage.
Israel’s offensive in Gaza has led to the deaths of more than 56,500 people, according to the Hamas-run health ministry, which does not differentiate between civilians and combatants.

Media watchdog Ofcom has said the BBC “clearly has questions to answer” over the live stream from Glastonbury.
A BBC spokesperson said: “The director-general was informed of the incident after the performance and at that point he was clear it should not feature in any other Glastonbury coverage.”
The broadcaster respects freedom of expression but “stands firmly against incitement to violence”, they said.
They added: “The antisemitic sentiments expressed by Bob Vylan were utterly unacceptable and have no place on our airwaves…
“The team were dealing with a live situation, but with hindsight we should have pulled the stream during the performance. We regret this did not happen.”
Many provisions of the legislation, which received overwhelming support in the state House and Senate, take effect on Oct. 1.
