Crypto News Today: Fourth Wave of Coldcard Attacks Hits as Large Holders Sell Bitcoin

Last Updated: August 3, 2026

Today’s Top Stories

• Fourth wave of Coldcard hardware wallet attacks drains 389 BTC. The latest attack exploiting Coldcard’s firmware vulnerability extends a security saga that began July 31, when a bug present since 2021 was first disclosed. Coinkite has continued urging affected users to migrate funds to new, secure wallets immediately.
• Large Bitcoin holders sell into recent strength. The selling pressure has discouraged the usual dip-buying demand that cushions pullbacks, contributing to today’s broader market decline alongside the renewed security concerns.
• Bitcoin tracks gold at roughly 63% correlation. The elevated correlation reflects a broader shift toward safe-haven positioning during the current bout of market uncertainty, according to market analysts tracking cross-asset relationships.
• Zcash decouples from the market for a second session. ZEC posted its second consecutive daily gain even as most majors fell, reinforcing growing confidence in the network’s post-Ironwood security recovery.
• HBAR remains stuck in a descending technical channel. Hedera’s token has now underperformed the broader market for four straight sessions, with technical analysts citing persistent selling pressure without a specific identified catalyst.
• Today’s ISM manufacturing survey kicks off a busy macro week. Consensus expects a recovery to 54.0 for July, with the report the first of several data points ahead of Friday’s jobs report and next week’s CPI release.
• XRP Ledger ecosystem and Polkadot named top-gaining sectors. Both categories posted standout performance even as broader majors traded lower, according to market-wide sector tracking.

Regulatory and Calendar Watch

The Senate’s summer recess, beginning around August 7, is set to effectively close the CLARITY Act’s near-term legislative window, with any further progress on the crypto market-structure bill now expected to wait until the fall session. This week’s macro calendar is dense: today’s ISM survey, Friday’s jobs report, and next week’s CPI release and Aptos token unlock are all on deck.
