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Adding to investor optimism, Coinbase saw over $1 billion worth of Bitcoin withdrawn on May 9, marking the highest net outflow recorded in 2025 so far, triggering analyst predictions of a supply-shock driven Bitcoin rally.
