News emerged on May 15 indicating that Coinbase has become the victim of a $20 million extortion scheme, wherein cybercriminals enlisted overseas customer support agents to leak sensitive user information for fraudulent schemes. Although the breach reportedly impacted fewer than 1% of Coinbase’s monthly active users, the company anticipates that the costs associated with addressing and compensating victims of these phishing attacks could range between $180 million and $400 million, as Coinbase committed to reimbursing all those affected.
### Investor Sentiment Remains Positive
In spite of the security breach targeting the world’s third-largest cryptocurrency exchange, investor confidence appears to be robust. The Fear & Greed Index, a popular market sentiment gauge, continues to reflect a strong “Greed” sentiment, remaining above 69, as per data from CoinMarketCap.
### Significant Bitcoin Withdrawals Signal Optimism
Adding to the positive sentiment among investors, Coinbase experienced Bitcoin withdrawals exceeding $1 billion on May 9, marking the highest net outflow recorded in 2025 thus far. This event has prompted analysts to speculate on a potential Bitcoin rally driven by supply constraints.
### Details of the Extortion Attempt
Coinbase disclosed on May 15 that it faced a $20 million extortion attempt after cybercriminals collaborated with external customer support agents to gain unauthorized access to user data. The exchange clarified that these individuals leveraged their access to customer support systems to pilfer account information from a limited number of users. Importantly, Coinbase emphasized that no passwords, private keys, funds, or accounts tied to Coinbase Prime were compromised. The company reported that fewer than 1% of its monthly transacting users were affected by this breach.
### Coinbase’s Response to the Attack
Following the data theft, the attackers demanded a ransom of $20 million in Bitcoin in exchange for not revealing the breach. Coinbase rejected this demand and instead offered a reward of $20 million for information leading to the identification and prosecution of those behind the extortion.
### Institutional Demand for Bitcoin on the Rise
Coinbase is witnessing a surge in institutional interest in Bitcoin, as evidenced by its record daily outflows on May 9, when 9,739 Bitcoin—valued at over $1 billion—were withdrawn from the platform. This figure represents the highest net outflow recorded in 2025, according to André Dragosch, head of European research at Bitwise.
### Market Factors Influencing Bitcoin Outflows
The substantial outflow occurred while Bitcoin was trading above $103,600, coinciding with the announcement of a 90-day reduction in reciprocal tariffs between the U.S. and China. This development has alleviated market anxieties and bolstered overall investor sentiment.

The SEC’s decision to defer the listing of Grayscale’s Solana Trust ETF on the New York Stock Exchange has been pushed to October 2025.
### Starknet Reaches Decentralization Milestone
