Inside the Coldcard Hack That Drained Over $100 Million in Bitcoin: Uneasy Money

A hardware wallet's 5-year-old randomness bug just let hackers drain over $100 million in Bitcoin. How many more waves are coming? Plus, Ethereum's fight over cutting ETH issuance. ======================================================== Thank you to our sponsors! ⁠⁠⁠⁠⁠⁠Cape⁠⁠⁠⁠⁠: Your biggest crypto vulnerability isn't your wallet, it's your phone number.

Taylor Monahan makes the case that the culprit is not North Korea but professional GPU crackers, and explains why the dice-rolling ritual many early victims trusted still left them exposed. Sonya Kim, co-founder of 3F Labs, and Mike Silagadze, founder and CEO of ether.fi, debate where DeFi's responsibility ends after trade.xyz's SK Hynix perp swung from $1,128 to $917 on a thin premarket print, then turn to Ethereum's own monetary policy fight. That fight centers on EIP-8361, a proposal to cut ETH issuance that opened with only 48 hours for public comment, reviving the minimum viable issuance debate Sonya once worked through at Steakhouse. Silagadze calls cutting issuance economically unsound and warns it could push billions of dollars of ETH out of staking, while Kain Warwick argues the resulting chaos is good for an Ethereum governance culture that had grown too quiet. The conversation covers Coldcard's entropy failure, the dice rolls that did not save early victims, trade.xyz's oracle mispricing, and Ethereum's issuance fight.
