We dive into GameStop's surprising announcement to raise $1.3 billion in convertible notes, potentially to buy Bitcoin. The hosts explore how this connects to the 2021 meme stock saga that gave GameStop its massive cash position, Ryan Cohen's relationship with Michael Saylor, and whether this Bitcoin strategy is a life raft for a retail gaming business in decline. With GameStop's revenue dropping from $8.5B to $3.8B over eight years, is this a smart pivot or just vibe investing?Notes:- GameStop announces $1.3B convertible note offering- Revenue declined from $8.5B to $3.8B in 8 years- Company has $4.76B cash on balance sheet- Cash position largely from 2021 meme stock frenzy- Zero debt after paying off all loans- Saylor posted photo with Ryan Cohen: "Team Bitcoin"Check out our Bitcoin scaling conference!

What Satoshi Got Wrong About Bitcoin
Peter Todd joins us to talk about Bitcoin's technical evolution, discussing terminology like "blockchain" vs "timechain," and revealing flaws in Satoshi's original design. Peter dives deep into mining economics, explaining the risks of block withholding attacks, the problems with activation mechanisms for soft forks, and controversial funding models like demurrage. Despite surviving significant challenges, Bitcoin faces ongoing security concerns as block rewards diminish, requiring creative solutions to ensure mining remains economically viable long-term.Notes:- Block withholding attacks remain an unsolved risk- Mining rewards currently ~0.5% tax on Bitcoin savings- Bitcoin difficulty algorithm relies on halving events- Miners have ~24-30% hash power can disrupt network- Transaction fees alone insufficient for mining economics- Demurrage could stabilize mining revenue long-termCheck out our Bitcoin scaling conference!
