Bitcoin can settle $100, $1 million, or $10 million in about 10 minutes, 24/7, 365.

1. Bogleheads on Investing episode 71 centers on Matt Hougan explaining blockchain, Bitcoin, and cybercurrencies for Rick Ferri. 2. Rick Ferri hosts, and Matt Hougan is the Chief Investment Officer of Bitwise Asset Management and former CEO of Inside ETFs and ETF.com, which matters because he connects Boglehead thinking to crypto markets. 3. The episode asks what blockchain is, how Bitcoin uses it, and why a Boglehead audience should understand a trillion-dollar asset class. 4. Ferri says Bitcoin is about $1.5 trillion and the wider cybercurrency ecosystem is north of $2 trillion. 5. Hougan says blockchain is a database everyone can see into, but no single person controls. 6. He compares that model with Wells Fargo, Google, and a personal Excel spreadsheet. 7. Hougan traces blockchain ideas to decades of computer science research at MIT, Stanford, and the NSA. 8. He says cryptology, especially SHA-256 hashing and public-private key cryptography, underpins Bitcoin ownership and transfer. 9. Ferri and Hougan describe the first Bitcoin purchase as two pizzas bought for about 14,000 Bitcoin on May 22, 2010. 10. Hougan says Bitcoin grew through speculation, gray-market utility, and later broader institutional adoption such as a spot Bitcoin ETF and BlackRock ownership. 11. He also says central banks and the Federal Reserve create currency out of thin air, while Bitcoin uses miners instead. 12. Mining is presented as the process that validates blocks of transactions and rewards one miner with 3.125 Bitcoin. 13. Hougan says transaction fees are added so miners prioritize certain transfers, and those fees are about 10% of block revenue. 14. He explains that Bitcoin has a fixed supply of 21 million coins and that issuance halves every four years. 15. Hougan says the system adjusts when miners leave, because fewer miners raise the odds for the ones that remain. 16. He says the network automatically changes the math difficulty to keep block timing near 10 minutes. 17. The tone is technical but explanatory, with Ferri interrupting often to restate concepts in plain language. 18. The format is a long-form interview that moves from definitions to mining, valuation, and competing blockchain designs. 19. Listeners interested in Bitcoin mechanics, ETF structure, and monetary systems will likely want this episode. 20. Listeners wanting market commentary without technical detail will probably skip it.
