BITCOIN HACK: $40 Million Stolen from Cold Card Hardware Wallets

Jul 31, 2026

Bad news for Bitcoin holders: $40 million was stolen out of Cold Card hardware wallets, briefly spooking the market, though Bitcoin itself is fine.

  • Hackers drained $40 million from Cold Card hardware wallets β€” usually the safest way to store Bitcoin.
  • The wallets weren't broken; the seed phrase (the password) was generated without enough randomness, so it could be guessed.
  • Only affects Cold Card Mark III wallets on firmware after 4.0.1 β€” move funds off ASAP if you own one.
  • Bitcoin dumped on the news but may already have absorbed the panic; support sits near $62K.
  • A strong close for the US stock market into the weekend could help Bitcoin bounce next week.

Outlook: Expect a possible dip to grab liquidity near $62.2K, then choppy sideways trading, with a chance of a small recovery next week if stocks stay strong.

## Bitcoin Levels

  • **Bias:** Neutral-to-slightly bullish short term β€” weekly bullish divergence still active, but momentum is weak.
  • **Support:** $62.6-62.7K immediate; then $62.2K, $61.6K; major support at $60K.
  • **Resistance:** $66-67K.
  • **Targets:** Downside liquidity grab likely at $62.2K within 1-2 days.
  • **Invalidation:** A break below $60K would break the strong support zone.
