Bitcoin held above $63,000 while Ethereum stayed near $1,877, but the day's defining move came from a catastrophic cold-wallet exploit and a speculative microcap frenzy. The Coldcard vulnerability expanded to 4,585 addresses with combined losses reaching approximately 1,367 BTC, or nearly $89 million, across three attack waves. Separately, a newly launched ASTEROID token on BNB Chain exploded 1,557.69% in 24 hours, allegedly tied to a former BNB Chain employee's unauthorized wallet deployment and subsequent insider sale.
