  • AI data centers pay 60x more per megawatt, pushing industrial miners out of power markets.
  • $50 ASIC miners are heating homes, paying owners while replacing propane and gas furnaces.
  • Open-source software and solar automation turn miners into responsive, monetizing home appliances.

AI’s energy appetite has turned Bitcoin mining into a residential heating business. Industrial farms, priced out by data centers that can pay 60 times more per megawatt-hour, are abandoning the field to home miners.

Marty Bent, on TFTC, explains that the industrial pivot clears space for a decentralized resurgence. Home miners are snapping up old data center hardware - S19 miners now sell for $50 - and repurposing them as programmable furnaces. The heat a miner generates isn't waste; it’s a product. Tyler from Exergy argues for a “useful miner” framework where Bitcoin rewards act as a rebate on heating bills, cutting costs 40-50% compared to propane in some regions.

“We’re seeing a shift toward building-integrated mining where the hardware acts as a primary heat source. The miner doesn't need to be profitable in a vacuum; it only needs to be cheaper than the alternative fuel.”

- Tyler, TFTC: A Bitcoin Podcast

Technical hurdles are falling. Dylan, also from Exergy, describes using Home Assistant software on a Raspberry Pi to turn loud, rigid ASICs into smart home devices. This “building brain” integrates solar inverters, thermostats, and Bitcoin price feeds to automate decisions, cranking up miners when solar panels produce surplus and dialing them back for domestic peace.

AI tools like Claude are writing the automation scripts, lowering the barrier from engineering project to set-and-forget system. The vision, as Tyler outlines, is a future of integrated mining gadgets that autonomously manage home energy, forming a distributed foundation for the monetary network.

The historical parallel is stark. In an earlier analysis, Alex Waltz noted on the Bitcoin Takeover Podcast that Satoshi Nakamoto manually paused the nascent Bitcoin network eight times to let others join, ensuring decentralization from day one. The current shift from centralized megafarms back to basements echoes that original, deliberate design.

“These gaps were an invitation for the world to catch up. If Satoshi hadn't paused, the difficulty would have adjusted to his solo hash rate, making it impossible for newcomers to join.”

- Alex Waltz, Bitcoin Takeover Podcast

This isn’t a retreat; it’s a recalibration. The network is settling into a “low energy state” where hash rate disperses to where the heat is actually needed, improving resilience. The future of Bitcoin mining isn’t in a Texas warehouse; it’s in a hundred thousand basements.

S17 E31: Alex Waltz Reveals Bitcoin's First Miner • Jul 2

  • Alex Waltz's research, published on 1stbitcoinminer.com, identifies Dustin Trammell as the second active Bitcoin miner, challenging the common belief that Hal Finney held that position.
  • Dustin Trammell proved access to the private key for block 309 and claimed to have mined block 78, despite an early Bitcoin client bug that prevented broadcasting blocks and default-disabled mining.
  • Bitcoin's early code, specifically version 0.1.0, contained a bug that prevented nodes from broadcasting newly mined blocks and an extranonce counter that did not reset unless the node restarted.
  • The Bitcoin network experienced eight significant time gaps between blocks during the first 170 blocks, consistently aligning with extranonce resets, suggesting periods when the sole miner turned off their machine.
  • Greg Maxwell, in an April 2013 forum post, disputed Sergio D. Lerner's claim that Satoshi mined almost alone until January 2010, asserting that he and others also mined during that period.
Also from this episode: (8)

Education (1)

  • Alex Waltz asserts that his research on the first 170 Bitcoin blocks provides a 'sterile environment' to strengthen Sergio D. Lerner's 'Poshi pattern' analysis, as there was minimal network noise.

History (1)

  • Satoshi Nakamoto initially used a clearnet IP address, located in a residential area of California, to operate the Bitcoin IRC channel, alongside a Tor node which Alex Waltz suggests was also Satoshi.

Protocol (4)

  • Alex Waltz found that Hal Finney's debug.log file from block 49 indicated only two nodes present when he joined: Satoshi's clearnet node and a Tor node, confirming Hal missed the network's launch.
  • Vlad notes that Ray Dillinger, a cryptographer who reviewed Bitcoin's early code in November 2008, perceived Satoshi as a genuine, non-motivated university student.
  • Vlad praises Zcash for achieving better scaling and mobile wallet functionality, evolving from its initial focus on strong privacy, and notes its proposal for Bitcoin was rejected.
  • Paul Sztorc, CEO of Layer2 Labs, plans to fork Bitcoin in late August 2024 at block 964,000 to launch a new network called 'ECash,' providing an airdrop to existing Bitcoin holders.

Media (2)

  • Alex Waltz dedicated five months to researching and five months to filming his 'First Bitcoin Miner' documentary, followed by two months of post-production.
  • Alex Waltz is also producing 'How to Install Bitcoin Core,' a narrative tutorial film about verifying PGP keys, and 'Satoshi Doesn't Exist.'

#765: The Bitcoin Home Mining Playbook with Exergy • Jul 1

  • Tyler and Dylan developed a playbook to educate on integrated home mining, emphasizing its utility as an energy infrastructure tool for heating, solar, and battery systems.
  • Tyler, author of "Bitcoin Mining Heat Reuse," highlights that the Heat Punk Summit brings together mining developers and building/energy professionals to integrate miners into heating systems.
  • Dylan states Exergy found industrial miner control software unsuitable for home use, leading them to develop custom control systems that adapt these devices for residential applications.
  • Tyler introduces the "useful miner" framework, where Bitcoin miners provide value by offsetting heating costs or monetizing excess solar, rather than solely needing to be profitable on electricity rates.
  • Tyler and Dylan advise converting various heating fuel costs (natural gas, propane, electricity) to an equivalent dollar per kilowatt-hour to accurately compare with Bitcoin mining operational costs.
  • Tyler stresses that a longer heating season, or high duty cycle, for a Bitcoin miner enhances its economic viability by maximizing run time and accelerating the payback of upfront hardware costs.
  • Tyler explains that monetizing excess home solar power with a Bitcoin miner often yields better financial returns than selling it back to the grid for minimal utility credits or airline-mile-like payouts.
  • Commercial and industrial facilities are well-suited for integrated Bitcoin mining due to economies of scale, longer heating duty cycles, existing intelligent building management systems, and favorable commercial electric rates.
  • Tyler recommends sizing miner heating systems for a building's average heat load (baseload) rather than peak demand, optimizing miner uptime and avoiding excessive capital expenditure on underutilized machines.
  • Dylan and Tyler advocate for a hybrid heating approach, integrating miners with existing furnaces or boilers, where a 'building brain' intelligently switches between energy sources based on real-time economics.
  • The "building brain" is a local, self-hosted system (like Home Assistant) that aggregates data from energy costs, Bitcoin prices, thermostats, and solar inverters to make autonomous heating and monetization decisions.
  • Dylan highlights Home Assistant as a powerful open-source software, running on platforms like Raspberry Pi, which serves as an input aggregator and automation server for various IoT devices, including Bitcoin miners.
  • Tyler notes that AI tools, when combined with open-source smart home platforms, significantly lower the barrier to entry for users to create and manage complex automations for home Bitcoin mining systems.
  • Dylan explains hardware selection for home mining depends on the specific goal, such as space heating or solar monetization, and available electrical infrastructure, with modular space heaters offering an easy starting point.
  • Dylan cites a case where a single M64 miner supplied 99% of a customer's heating demand for several months, proving that residential heating systems are often over-sized for worst-case conditions.
  • Tyler reports that S19 Bitcoin miners are currently available for $50 to $100, representing an affordable entry point for individuals interested in home mining setups.
  • Tyler acknowledges a significant challenge in mainstream adoption is the HVAC industry's lack of familiarity with hybrid heating systems and baseload sizing, as they typically size for peak demand.
  • Dylan anticipates a future where solar salesmen upsell Bitcoin miner kits instead of batteries, monetizing excess solar power, especially as grid buyback rates for homeowners decline.
  • Dylan views the pivot of industrial miners towards AI compute, which offers 60x higher profitability per megawatt-hour, as beneficial for home miners due to reduced network hash rate and difficulty.
  • Tyler asserts that ASIC manufacturers must adapt by developing hardware and firmware specifically for energy infrastructure applications, as industrial data center demand for traditional miners shifts.
  • Tyler and Dylan advocate for an open-source ASIC stack, including firmware like Mojina from the 256 Foundation, and accessible chips with standardized form factors to foster innovation and consistency in the mining industry.
  • Dylan explains that Mojina, an open-source firmware, combined with Libreboard hardware, allows for flexible configurations like mixing hashboards and programmatically dictating power distribution for optimal mining.
  • Dylan outlines that Bitcoin earnings from pooled mining can be received via on-chain transactions (Ocean requires 1M sats minimum) or instantly through Lightning Network payouts.
  • Tyler champions decentralized mining pools like Peterpool V2, which operate as a share chain protocol rather than a central entity, enhancing digital decentralization of the Bitcoin network.
  • Tyler envisions a future where integrated Bitcoin mining gadgets autonomously manage home energy, monetize solar, and offset heating costs, forming a distributed and robust foundation for the monetary system.

Untapped Growth | Bitcoin And Revisited • Jun 30

  • Joel applies Alan Savory's "Holistic Management" principles to his operation, noting the framework's broad applicability from ecology and soil health to business strategy and team leadership.
  • Joel's "piney woods" cattle, an ancient, resilient Spanish breed, have a 30-month finishing time, leading to an almost four-year payback period. He considers this a long-time preference investment in "animal wealth," valuing ancestral resilience over fast yield.
  • Joel proposes regenerative grazing as a viable career path where a manager working 5-6 hours weekly can oversee 200-250 cattle across multiple properties, potentially generating $200,000-$250,000 annually.
  • The highly regulated butchery industry centralizes power and stifles small producers, forcing Joel to use "libertarian processing" (selling live animals for on-site butchering) while advocating for legislative change.
  • Joel's decentralized grazing co-op uses "cow share" legal precedents to match ranchers and investors, splitting animal offspring rather than involving complex business agreements. This model builds on the raw milk herd share framework.
  • The co-op model offers investors a hard asset (animals) that is inflation-secured, yields new calves annually, and provides a sustainable meat supply for families. This diversifies wealth beyond traditional investments.
  • An investment group proposed a land trust model to Joel where they acquire degraded land, and homesteaders, in exchange for stewarding and regenerating it with livestock, receive a small acreage (1-2 acres) for their homestead.
  • Joel notes that collaborating with people sharing a "Bitcoin mindset" - characterized by goal orientation and precise communication - significantly reduces friction and accelerates project development compared to fiat-minded individuals.
  • David Bennett postulates that vast tracts of chemically degraded commodity farmland may soon collapse, creating opportunities for regenerative methods to restore soil and productivity quickly, transforming barren landscapes into vibrant ecosystems.
Also from this episode: (7)

Protocol (1)

  • David Bennett's "Bitcoin and" podcast explores Bitcoin's "edge effect," intersecting it with diverse fields like regenerative agriculture, gaming, and education to gain a deeper understanding of these overlapping systems.

Biology (5)

  • Joel, from Untapped Growth, launched untappedgrowth.com in April 2021, a platform enabling participation in regenerative agriculture through a "choose your own story" model that connects investors with homestead ranchers.
  • Regenerative agriculture fundamentally seeks to heal both the human condition and the soil, recognizing that the planet's wealth generation primarily stems from six inches of topsoil and rainfall.
  • David Bennett suggests that the gut's extensive neurology indicates it processes environmental "information" from food, theorizing that food allergies may stem from consuming non-local products that confuse this internal sensing.
  • Joel operates a regenerative cattle farm on 28 acres of pasture, 30 acres for wildlife, and 50 acres of scrub woods, which he leases for $1 annually. This arrangement benefits the landowner by reducing residential tax rates and eliminating mowing.
  • Joel explains that "animal wealth" goes beyond mere numbers, encompassing the deep resilience and genetic adaptability of animals like his Pineywoods cattle, which thrive with minimal inputs unlike modern breeds.

Health (1)

  • His personal journey into regenerative agriculture began with severe health issues in 2009, leading him to holistic health and later to Bitcoin as a solution for censorship-resistant commerce needed for self-sovereign communities.
