Coldcard Exploit Tops $88M
Galaxy Research's Alex Thorn flagged a suspected fourth wave of Coldcard thefts on August 3 — around 449 BTC from roughly 709 addresses and still climbing — on top of the roughly 1,367 BTC (~$88.6 million) from 4,585 addresses across three earlier waves, all tied to a March 2021 firmware flaw that generated guessable seeds. Thorn characterised the newer sweeps as likely copycats exploiting the public flaw, and noted some transactions remain unconfirmed, giving affected users a narrow window to rescue funds via higher-fee replacement transactions. Coinkite halted shipments, destroyed vulnerable stock, and urged immediate migration; Bloomberg analysts questioned whether a roughly five-person team can carry the security load, per coverage.
Ethereum ETFs Take $365M in July — Double Bitcoin's Weakest Inflow Month Since Launch
US spot Ethereum ETFs took in $365.17 million in July, their best month this year after two months of $1 billion-plus combined outflows, per SoSoValue data — more than double Bitcoin ETFs' $172.4 million, which broke a two-month outflow streak but ranked as their weakest inflow month since launching, and closed with a $265 million single-day outflow on July 31. CryptoSlate's analysis noted ETH valuation metrics remain above levels tied to past cycle bottoms.
