How Bitcoin Treasuries Will Cause The Next Bear Market
Charlie and Colin dive deep into the dangerous parallels between today's Bitcoin treasury companies and the 1929 investment trust bubble. They analyze how companies like MicroStrategy use convertible debt to accumulate Bitcoin, why this creates systemic risk, and how forced selling could trigger a catastrophic unwind. From Ponzi-like dividend structures to the speculative attack strategy, they break down why this leverage-fueled boom might end badly.

Bitcoin Needs Self Custody To Survive
Nick Neuman, CEO & co-founder of Casa joins us to talk about why Bitcoin's future depends on self-custody adoption. Neuman argues that without users holding Bitcoin "at the edges" and generating transaction fees, mining incentives could collapse, potentially forcing changes to Bitcoin's 21 million supply cap or pushing institutions toward proof-of-stake alternatives.

NOTES:
• Casa founded in 2018 to enable self-custody
• Coinbase holds 2.8 million Bitcoin today
• Transaction activity lower than 2018 levels
• Bitcoin block reward halves repeatedly over time
• Mining unprofitable without transaction fees
• 2140 deadline for block reward depletion
