THE Bitcoin Podcast

“If the internet could move value natively… would you use anything else?” I sit down with David Marcus, a true fintech veteran and the co-founder and CEO of Lightspark. You might know him from his time at PayPal, Meta where he led Messenger, or the ambitious Libra/Diem project. Now, he’s on a mission to build the open internet of money—on Bitcoin. We dive into David’s fascinating journey through startups, global payments, and Silicon Valley, before unpacking the philosophy and architecture behind Lightspark. We explore how Bitcoin is evolving beyond store of value into a global settlement layer, how Spark enables stablecoin issuance and self-custodial wallets on Bitcoin, and why compliance, scalability, and user experience are critical for mass adoption.

"I am incredibly, incredibly bullish right now." In this episode, I chat with Marty Bent, co-founder of TFTC, host of Rabbit Hole Recap, and one of the most clear-headed voices in Bitcoin media. We dig into the state of Bitcoin markets and why Marty remains deeply bullish despite volatility, before moving into a wide-ranging conversation on Nostr, live streaming, and the cultural shift toward open protocols. If you’re trying to understand how Bitcoin, family, culture, and politics all collide in this moment, and where optimism still makes sense, this episode is for you.

Today I talk with Keonne Rodriguez, co-founder of Samourai Wallet, who is set to report to prison on December 19 unless he gets a pardon from President Trump… In April 2024, two Bitcoin software developers, Keonne Rodriguez and William "Bill" Lonergan Hill, were violently arrested in their homes in a pre-dawn militarized raid by the FBI for running Samourai Wallet—a non-custodial Bitcoin wallet—despite no prior warnings and full compliance with the law as they and their advisors understood it. Keonne on X: https://x.com/keonne GET INVOLVED: https://billandkeonne.org/ SIGN THE PETITION: https://www.change.org/p/stand-up-for-freedom-pardon-the-innocent-coders-jailed-for-building-privacy-tools DONATE: https://www.givesendgo.com/billandkeonne They spent the next year and a half in the crippling uncertainty of home arrest, fighting against an adversary with unlimited resources. Keonne was sentenced on November 6, 2025, to the maximum five years in prison, plus an additional fine of $250,000, plus three years of supervised release. Bill was sentenced to four years in prison on November 19, 2025. He will also be responsible for a $250,000 fine, and three years of supervised release. Both men are facing serious time in jail for writing code that supported the privacy and security of Bitcoin users. This case exemplifies DOJ overreach through a dangerous legal theory that criminalizes open-source code for legitimate privacy purposes. Developers should not be held liable for bad actors using their software.

In this episode, I chat with Preston Pysh, investor, educator, and host of Bitcoin Fundamentals on The Investor’s Podcast Network. We dive into everything from confusing macro signals and monetary policy pivots to his thoughts on the evolution of the four-year cycle. We also get into the political chess game of the Fed, what Trump might be planning for Powell’s replacement, and how institutions like Harvard are signaling strong conviction in Bitcoin. If you’re trying to make sense of the weird vibes in the market, this episode is for you.

"Bitcoin is the best money that humanity has ever invented, discovered, whatever you want to say. There's 21 million forever. There's infinite fiat forever. Do the f***ing math. This isn't that complicated. You just have to stack sats." This is episode one of BITCOIN AFTER DARK. These episodes are originally live streamed as "emergency broadcasts" and I figured I might as well put them out as regular episodes. If you are bearish or worried about bitcoin right now, then this episode is for you. For this rip I'm solo for the first part then joined by Nathan from Bitcoin Mentor (links below).
