Do the Coldcard attacks mean all hardware wallets are now insecure？

Just when you thought crypto market morale couldnt sink any lower, along comes the Coldcard entropy bug to prove you wrong.　　The discovery of a flaw in one of the industrys longest-running hardware wallets last Friday serves as a stark reminder that there is no perfectly safe place to put all your Bitcoin.　　Coldcard disclosed the entropy-generation flaw affecting multiple Coldcard devices on July 31.

The $120 million Coldcard hack lights up Bitcoin's memory pool

Increasing network activity is often said to support valuations for the networks native coin, bitcoin . So far, the token has neither rallied nor dropped significantly and remains boxed in the recent range of $62,000–$65,000.　　Analysts continue to point to the fate of the Clarity Act as the immediate catalyst while citing longer-duration government bond yields as a more macro and longer-lasting one.　　“CLARITY is still the immediate policy binary. The Senate has a three-day window before its August 10 recess, while the implied probability of passage by year end has fallen to 23% from around 75% in mid-May. A push to attach prediction-market restrictions adds another process risk,” analysts at Marex said.　　Meanwhile, Bitfinex said the bullish macro case for bitcoin could collapse if the real or inflation-adjusted yield on the U.S. 10-year Treasury note tops 2.5%.　　“The 10-year real yield has not stayed above 2.5% since before Bitcoin existed, so there is no price history above that line. It is now at 2.41%, nine basis points below,” the exchange said.　　Stay alert!
