Episode Description from the Publisher

The failure, in plain terms A March 2021 firmware change altered how Coldcard generated entropy, leaving seeds near 40 bits instead of the 128 or 256 that makes the cryptography uncrackable, so attackers could simply run the space Who it hit Galaxy's tracking showed the first wave alone above 1,000 Bitcoin and roughly 1,400 to 1,500 total, weighted toward long-time savers stacking modest amounts rather than large addresses This was not a self-inflicted loss Isaiah drew the line clearly: people who use leverage and lose have made a choice, while these holders researched, chose the device with the strongest reputation, and still had nothing they could have done differently The warnings existed A seed collision in 2022 had two users seeing each other's transactions, and a later technical question was written off as FUD, which is why Guy Swan's point landed: the temperament you want in someone securing your savings is one that welcomes being told it might be broken The community response was the bright spot Rescues ran all weekend, and the decentralized Bitcoin Red Team has scanned around 425 Bitcoin repositories, funded by donations covering model access rather than by any single company One holder's response stood out Someone who lost roughly $1.6 million posted six days later that he was rebuilding his stack, still believed in Bitcoin, and would still self-custody Multisig held up Brady saw few or no reports of Coldcard multisig quorums being swept, because pairing keys is hard without the descriptor, and MARA's Slipstream let people move those funds through a private mempool instead of exposing them Swan is not advising Vault clients to move funds Vault runs two Blockstream Jades, chosen after a thorough review of the options and explained in Yan Pritzker's article published the same day, and Swan has now begun evaluating a second vendor so multi-vendor becomes an option Calle's finding is the AI story of the week Not one vulnerability was found by a US frontier model, while roughly $10,000 a day goes to open-weight models to audit Bitcoin infrastructure, because the American models refuse cybersecurity work outright Why we still need Bitcoin A year's salary buys about 90% less gold than in 1971, monetary inflation has run 396% against CPI's 96%, and real discretionary income after food, gas, interest and rent has fallen since 2011 ► For high-net-worth individuals and corporations seeking to build generational wealth with Bitcoin, Swan Private is your guide    ✔ https://www.swanbitcoin.com/private?utm_campaign=private&utm_medium=sponsorship&utm_source=podcast&utm_content=swan_signal_live ► Secure your bright orange future with the Swan IRA today!
