According to Crypto Rover, Coinbase shares ($COIN) fell by 4.1% after the company disclosed it anticipates up to a $400 million loss resulting from a recent cyber attack (source: Crypto Rover, May 15, 2025). This significant financial setback raises concerns about security vulnerabilities in regulated crypto exchanges and could heighten volatility in related crypto assets. Traders should closely monitor potential spillover effects in both Coinbase-linked tokens and the broader cryptocurrency market, as investor sentiment may shift in response to increased risk perception.
