A class action lawsuit against Coinbase alleges delayed disclosure of a significant data breach and potential regulatory violations in the UK. The complaint focuses on Coinbase’s handling of the incident and raises concerns about its transparency and customer security practices. 7.2% decline in Coinbase’s stock (COIN) reflected investor unease following the news, highlighting the impact on shareholder trust. This incident follows previous data breaches, potentially leading to increased regulatory scrutiny for crypto exchanges. Coinbase CEO Brian Armstrong acknowledges steps taken to strengthen security measures and address the impact on affected customers. The legal challenges facing Coinbase could result in financial penalties ranging from $180 million to $400 million for remediation costs.
