This Bitcoin Boiler Pays for Itself in 2 Years
Elmeri Suomi runs a heating company that happens to mine Bitcoin. His product, the SunBit Bitcoin Boiler, drops one or two hydro-cooled ASICs into a water tank, heats a house to 60°C, and lets the mining revenue pay the power bill — in the best case leaving the homeowner in profit on their heating. He started in water-to-air heat pump sales, began mining as a hobby in 2020, and founded SunBit in 2023 once the two worlds clicked.In this episode we get into the economics that make consumer-scale mining work at 7–12¢/kWh power: not fat mining margins, but offsetting an oil bill that can run 3,500 litres a year at €1.80/litre. Elmeri walks through the ROI (two years best case, five years worst), why he explains everything in cents per kWh instead of hashprice, and how spot-price optimisation and solar over-production feed into the tank.We also cover why he abandoned immersion after too much grey hair — dissolved cooling paste, dead S21s and oil everywhere — and landed on hydro; why the boxes are Antminers, not Whatsminers (60°C is all you need once you're past Legionella at 52–55°C); the 3×25A wiring that lets it fit a normal Finnish home; the first installs in Kotka and Nokia plus the first international job in the Netherlands; and the pre-seed raise now funding a 100 kW industrial version.Guest: Elmeri Suomi, CEO & Founder of SunBit OySunBit: https://sunbit.fi/enSunBit on X: https://x.com/SunbitOySunBit on LinkedIn: https://www.linkedin.com/company/sunbit-oy/Timestamps:0:00 Intro: a heating company that mines Bitcoin4:30 Where the savings really come from — offsetting the oil bill11:00 Explaining hashprice vs cents per kWh, pool and Lightning17:30 Skepticism, "is this legal?" and the remote-managed mini-PC23:00 Why hydro beat immersion — the grey-hair story29:00 First installs, the total market and the pre-seed raiseSponsored by:Luxor.

Zcash Miners Earn 7x Bitcoin's Revenue. But There's a Catch. [NEWS]
Hash price is holding at elevated levels, but Bitcoin mining is entering a very different kind of market. Public miners are shedding hashrate, AI infrastructure keeps absorbing power, and for the first time in years the network may be facing a genuine period of declining hashrate.In this news roundup: Zcash mining economics are exploding as Z15 Pros generate multiples of current Bitcoin mining revenue, Tether walks away from a $120M mining investment in Uruguay after a power dispute, Bitdeer approaches 9% of Bitcoin block rewards, and AWS + Nvidia plan another 2 million GPUs as AI infrastructure keeps expanding.We also look at Sweden's VAT crackdown on crypto miners, Bitdeer's $100M Texas land acquisition for AI/HPC expansion, Canaan pausing mining operations in Ethiopia, and Demand's new Stratum V2 transaction acceleration model that could change how mining pools compete for hashrate.The bigger question: if AI keeps winning the competition for power in developed markets, where does Bitcoin mining go next — and what happens when pools have to fight over a shrinking hashrate pie?🛠 Sponsored by:Altair Technology — ASIC hardware, replacement parts & mining infrastructureCode: HASHRATEUPhttps://altairtech.io/aff/125/Luxor — Mining software, firmware & hashrate toolshttps://luxor.tech/Timestamps:0:00 Intro — Hash price & difficulty outlook1:22 Zcash mining surge — Z15 Pro economics4:43 Tether's $120M Uruguay mining bet collapses7:04 Sponsor: Altair Technology7:30 Bitdeer nears 9% of Bitcoin block rewards8:00 AWS + Nvidia plan another 2 million GPUs8:48 Bitcoin miners outperform the AI trade9:32 Sweden's VAT crackdown on crypto miners11:52 Bitdeer buys 200 acres in Texas for AI/HPC expansion12:42 $31.6T projected data center spending through 205014:05 Sponsor: Luxor14:40 Public miners shed 56 EH/s as AI retrofits accelerate15:12 Canaan pauses Bitcoin mining operations in Ethiopia16:04 Demand brings transaction acceleration to Stratum V217:14 Bitcoin's first declining-hashrate environment17:58 Final thoughts & mining market opportunities📊 HashrateUp Hardware Deals: https://t.me/hashrateup📩 Free 5-Day Bitcoin Mining Course: https://hashrateup.com/newsletter-sign-up/#BitcoinMining #HashPrice #Zcash #ArtificialIntelligence #BitcoinHashrate #Bitdeer #Tether #DataCenter #StratumV2 #MiningPool #BitcoinNews #HashrateUp

They Could Have Built This Years Ago. Nobody Did.
Michael Schmidt, better known as Schnitzel, bought a hundred S19J Pros for $40 each. Machines that used to cost $15,000. He's bringing them back with open-source firmware he built in his garage, with help from an AI agent and about eight burned hashboards along the way.Michael is one of the lead engineers at the 256 Foundation, and he's back on the show to talk about Magina. It's an open-source firmware that does things Braiins, Luxor, Vnish and stock firmware simply won't. You can ramp a miner from 3,000W down to 1,000W in three to five seconds, where other firmware takes half an hour. You can follow a live solar curve. And you can run hashboards from completely different machines together in one rig, which no proprietary firmware will let you do.We talk about why nobody built any of this before, why the 256 Foundation wants open rigs but not open chips, and what happened when Michael handed an AI agent an S19 and a power meter and told it to figure things out. We also get into why your miner's power API is lying to you about wattage, what he learned from destructive testing across eight different hashboard variants, and where he thinks this all goes over the next two or three years.👤 Guest: Michael Schmidt (Schnitzel), Lead Engineer at the 256 Foundation256 Foundation: https://www.256foundation.orgFollow on X: https://x.com/schnitzelTimestamps:0:00 Intro: Schnitzel, Teddy the Swiss mountain dog & proof of dog3:04 The 256 Foundation: Libreboard, Ember One, Magina & Hydro Pool4:13 Heat reuse goes commercial: the Swiss solar monetization project5:00 The solar problem: chasing a production curve that never sits still5:31 Why existing firmware takes 30 minutes to change wattage6:35 Why nobody built sub-minute ramping before (and why it isn't malicious)9:18 Proprietary hardware: the tire manufacturer who only sells whole cars10:57 Open rigs, not open chips: what the 256 Foundation actually wants13:52 What Magina is and how it differs from Braiins, Luxor & Vnish15:06 Handing an AI agent an S19 and a Shelly power meter17:03 Zero to 500 MHz: the board that died and the ramping fix19:21 Destructive testing: 8 hashboard variants in a single S19J Pro20:22 Physical vs digital: 2,900W on the API, 0W on the wall22:10 Microphones, temp sensors and eight burned boards24:13 Why the power API guesses, and why the PSU already knows27:09 S19J + S19K on one control board: 130 TH/s from mismatched hardware31:30 Building a Frankenstein miner from two dead machines32:25 The $40 miner renaissance and bringing dead hardware back34:04 Magina on a Canaan Nano, Proto chips and the wildfire moment35:08 Get involved: dev calls, donations and hardware you're not using🛠 Sponsored by:Luxor.

Old ASICs, $0.058 Power & a 50/50 Profit Split w/ Ben Smith
Most people scrap their old ASICs, ship them overseas, or let them gather dust. Ben Smith (Bear Market Mining) offers a fourth option: profit-split hosting that keeps end-of-life machines online in the US. Ben joins me — you can hear the miners running in the background — to break down the model he built at his Walnut Ridge site: a 5.8¢/kWh all-in rate, a straight 50/50 split of net profit after power (60/40 on S21s), no deposits, no rack fees, and no long-term lock-in. We get into why he'd rather stack the Bitcoin than take your dollars, the 10,000-unit S19 redeployment that inspired the whole idea, why he doesn't think hashprice climbs back to $80, how he keeps six-year-old machines alive with a wall of spare parts and Braiins firmware, exactly how the pool split is calculated every 30 days, and his hard-won take on immersion cooling (spoiler: 180 machines still sit in his bath). Plus the hydro build, dry coolers running in 110°F heat, and the too-cold startup problem nobody warns you about.👤 Guest: Ben Smith — Founder, Bear Market Mining (President, Arkansas Blockchain Council)Bear Market Mining: https://bmmining.techOptimization Calculator: https://bmmining.tech/optimization.htmlSchedule a Consultation: https://bmmining.tech/apply.htmlContact: ben@bmmining.techTimestamps:0:00 Intro — end-of-life ASICs and the profit-split pitch5:00 Walnut Ridge: from immersion to air to hydro10:30 The profit-share model — 5.8¢ all-in and why Ben stacks BTC over dollars16:30 Redeploying dead fleets: the 10,000-unit S19 second-life story23:00 Profit-split incentives: downside protection vs giving up upside29:30 Why Ben doesn't think hashprice hits $80 again (Rockdale, difficulty, the bull case)36:00 The construction side: 200 MW built + becoming Arkansas' #2 power buyer42:00 Running old units: free part swaps, Braiins firmware & underclocking47:30 How the split actually works: Braiins pool, 30-day cycle, power paid first52:00 Full deal terms: no deposits, no rack fee — just ship it57:00 Hydro infrastructure, dry coolers & the too-cold startup problem1:01:00 Immersion reality check: why 180 machines still sit in the bath🛠 Sponsored by:Luxor — Mining pool, firmware, hardware trading & hashrate toolshttps://luxor.tech/Altair Technology — ASIC hardware, replacement parts & mining infrastructureCode: HASHRATEUPhttps://altairtech.io/aff/125/📊 HashrateUp Hardware Deals: https://t.me/hashrateup📩 Free 5-Day Bitcoin Mining Course: https://hashrateup.com/newsletter-sign-up/#BitcoinMining #ProfitSplitHosting #BitcoinHosting #ASIC #S19 #HydroCooling #BearMarket #Braiins #MiningPool #Arkansas #EndOfLifeASIC #Bitcoin #HashrateUp

Bitcoin's Back - Miners Are Quitting for AI Anyway [NEWS]
Bitcoin's back above $70K and hash price ripped more than 10% — from the lows of $31 all the way to $35. Great news for anyone running machines. But public miners are still dismantling capacity to chase AI money, and this may be the first true hashrate bear market ever.In this news roundup: a difficulty adjustment looms that could confirm bullish conditions, public miners have sold most of their BTC stack, Russia bans mining in Moscow through 2032, and the AI pivot keeps swallowing gigawatts — Riot's confirmed 20-year Anthropic lease, Core Scientific's Polaris deal, Cipher, TeraWolf, Ionic and more all trading Bitcoin mining for HPC. Plus the Zcash mining surge nobody saw coming.The big question: if the AI trade cracks — China chip progress, cheaper models like Kimi K3 — what happens to the capital funding these 20-year leases?🛠 Sponsored by:Altair Technology — ASIC hardware, replacement parts & mining infrastructureCode: HASHRATEUPhttps://altairtech.io/aff/125/Luxor — Mining software, firmware & hashrate toolshttps://luxor.tech/Timestamps:0:00 Intro — Bitcoin back above $70K, hash price $31 → $350:40 Upcoming difficulty adjustment — why it matters1:43 Core Scientific closes Polaris deal — 1.5 GW Oklahoma AI campus2:20 Cango's revenue halves as it pivots from mining to AI2:47 Bitdeer revenue +47%, shares down 77%4:42 Riot × Anthropic — 20-year Rockdale lease confirmed5:14 $573M debt for 191 MW AI conversion — the cost of pivoting7:10 Public miners selling BTC — 127K down to 29K7:52 Russia bans mining in Moscow region through 20328:20 Sponsor: Luxor9:51 Public miners shed 21% of hashrate as AI accelerates11:55 The first-ever hashrate bear market explained12:32 Cipher secures 900 MW Texas site + Black Pearl AI13:38 TeraWolf hits 71% AI leasing revenue14:16 Ionic — AI leasing replaces Bitcoin mining14:54 Sponsor: Altair15:25 Bitdeer's $400M Malaysia AI contract16:20 Is the AI trade cracking?

The Firmware Every Miner Needs w/ Brandon
Third-party firmware on WhatsMiner didn't exist. Now it does. Brandon McWard (Associate Product Manager, Firmware at Luxor) joins me on site — you can hear the ASICs — to walk through LuxOS running on an M50S+, live screen share, feature by feature. We cover why MicroBT stock firmware has been a closed box for years, how Advanced Thermal Management replaces the binary "sensor trips, machine off" logic, why changing a power target on stock firmware costs you a full reboot and retune, and the niche feature built for one oil field client: Hash on Disconnect, which keeps machines hashing synthetic work so the generator never takes the load swing. Plus chip-level temperature grids, the overhauled logs, the 2.8% fee structure, and what's actually different under the hood between Bitmain and MicroBT tuning. This is one to watch, not just listen to.👤 Guest: Brandon McWard — Associate Product Manager, Firmware @ LuxorLuxor: https://luxor.techLuxOS firmware: https://luxor.tech/mining/firmwareCompatible miners: https://docs.luxor.tech/firmware/compatibilityTimestamps:0:00 Intro & why third-party firmware on MicroBT is rare6:20 Stock MicroBT firmware: the closed box problem10:10 Time to tune & why power target changes cost you hashrate19:00 What role AI actually plays in firmware development22:00 GUI walkthrough: LuxOS running on an M50S+34:00 Board target, hot & dangerous temperature explained37:20 Save the generator, not the miner: Hash on Disconnect45:00 Top 2 features for WhatsMiner operators + LuxOS fees🛠 Sponsored by:Luxor — Mining pool, firmware, hardware trading & hashrate toolshttps://luxor.tech/Altair Technology — ASIC hardware, replacement parts & mining infrastructureCode: HASHRATEUPhttps://altairtech.io/aff/125/📊 HashrateUp Hardware Deals: https://t.me/hashrateup📩 Free 5-Day Bitcoin Mining Course: https://hashrateup.com/newsletter-sign-up/#BitcoinMining #LuxOS #Luxor #WhatsMiner #MicroBT #ASICFirmware #MiningFirmware #ThermalManagement #Curtailment #M50S #Bitcoin #HashrateUp

Why BIP-110 Was Dead on Arrival w/ Chris
Bitcoin nearly split in two. On BIP110 activation day, a chain split actually happened — and almost nobody noticed. Coinjoined Chris (Seedor, Bitsurance) joins me to break down what BIP110 really was, why it was dead on arrival with under 6% real node support and near-zero hashrate, and what it teaches us about how consensus in Bitcoin actually gets decided. We go deep on fake pubkeys, OP_RETURN limits, relay policy vs consensus, the OP_RETURN spam wars since 2023, mining pool centralization, and why the "economic node" — not one-node-one-vote — is what really matters. If you mine Bitcoin but never think about what your hashrate is actually securing, this one's for you.👤 Guest: Coinjoined ChrisX: https://x.com/coinjoinedSeedor (seed backup / self-custody): https://seedor.ioBitsurance (Bitcoin insurance): https://bitsurance.euTimestamps:0:00 Intro & who is Chris?3:22 The origins: NFTs, JPEGs & 2023 fee spikes5:34 Information theory & fake pubkeys7:30 UTXO bloat & node centralization13:18 Counterparty & what a node actually does17:35 Consensus rules vs relay policy22:43 DoS protection & who sets node defaults24:14 Sponsor: Altair Technology24:51 OP_RETURN limits & node implementations28:16 2023 spam onslaught & the push to change consensus32:11 The "garbage can" argument & the anti-spam steelman34:52 The bell curve & what consensus really is37:25 Signaling: node counts, sockpuppets & prediction markets39:47 BIP444 → BIP110: cramming in the changes44:15 Does the market even understand consensus?48:12 Under 6% support & why capital isn't your voice52:36 Ossification & the golden-rock debate53:44 Sponsor: Luxor55:59 BIP110 mechanics & what "activation" means59:37 Cooldowns, "longest chain" vs most chain work1:03:05 Activation day: the network splits live1:06:28 Roughnecks & the block race that stalled1:09:05 Pool power, centralization & OFAC censorship1:11:38 Stratum V2, Foundry & why miners don't care1:14:41 The economic node: not one-node-one-vote1:17:35 What we learned & what's next (BIP54)🛠 Sponsored by:Altair Technology — ASIC hardware, replacement parts & mining infrastructureCode: HASHRATEUPhttps://altairtech.io/aff/125/Luxor — Mining software, firmware & hashrate toolshttps://luxor.tech/📊 HashrateUp Hardware Deals: https://t.me/hashrateup📩 Free 5-Day Bitcoin Mining Course: https://hashrateup.com/newsletter-sign-up/#BitcoinMining #BIP110 #ChainSplit #BitcoinConsensus #SoftFork #OPRETURN #Ordinals #NakamotoConsensus #MiningPools #Bitcoin #HashrateUp
