Bitcoin Cold-Wallet Attack Hits 4,500 Addresses, $89M Lost
A sophisticated cold-wallet attack has spread to 4,500 Bitcoin addresses with losses approaching $89 million, raising alarms across crypto security circles.
A cold-wallet attack targeting Bitcoin holders has ballooned to over 4,500 compromised addresses, with total losses creeping toward $89 million. If you think your hardware wallet makes you untouchable, this story is a wake-up call. Cold storage has long been the gold standard for crypto security — this attack challenges that assumption hard.

When an attack of this magnitude unfolds in real time, the broader crypto market tends to feel the psychological weight, even if on-chain fundamentals stay intact. Watch for volatility if the source of the exploit gets publicly identified.
