Two open-source bitcoin mining control boards now exist. But why two? 🤔👇 We open sourced BCB100 in January. Then 256 Foundation announced their own FOSS board project. I was confused. Why not build on top of ours? They said their goals were different. That it’s easier to start from scratch… And now that we’ve seen more details, IT MAKES SENSE. Two boards. Two directions. BCB100 (by Braiins) 🟠 Built for industrial-scale uptime 🟠 Plug-and-play with any S19 miner 🟠 Tested in harsh real-world environments 🟠 Easily adaptable for new industrial models (e.g. swap fan connectors for S21 series) Libre Board (by 256 Foundation) 🔸 Built for home mining and DIY projects 🔸 Based on Raspberry Pi Compute Module (CM), modular and easy to expand 🔸 USB-C and WiFi support, great for small home setups 🔸 Ideal for tinkerers building heaters, automation, or custom rigs 🔸 Not built for high-density or industrial use The design focus is what separates them. Adapting Libre for industrial use is possible but not practical. Adapting BCB100 for new industrial use cases is faster and requires fewer changes. TWO BOARDS. TWO USE CASES. BOTH OPEN 🔥 Choose what fits. Let’s build!

I’m visiting the Lucky Miner factory in China this week. Got any questions or messages for the guy behind this closed-source Bitaxe clone? I’ll report back 👇

I’m still fat. Lost some weight by walking more, but it’s not enough. Target: 100 push-ups a day. Did 10 yesterday and everything hurts. Making it public so I can’t slack. Update in a month!

Six years ago, I quit my fiat job. Today I was flying a drone inside a mining container factory in China, shooting another behind-the-scenes video. Thanks, bitcoin 🤘

Historic moment in bitcoin mining: Bitdeer enters the hardware game. Here’s additional context based on comments from my previous post 👇 1️⃣ Machine reliability 2️⃣ Production 3️⃣ Tariffs 4️⃣ BTDR stock The excitement for Sealminer A2 has been strong. Some resellers claim they sold 15% of their stock in the first 24 hours. That’s a great start. But… In mining, early hype means nothing if the machines don’t survive long-term or if production can’t scale. 1️⃣ MACHINE RELIABILITY Let’s remember: no one outside Bitdeer has them running yet. Bitcoin miners have been burned before. Many times. So I highly recommend caution. Buy some units. Let them run. Wait to scale until the machines are battle-tested in harsh conditions for long enough. We still know very little about these machines or their software. And everything looks good on paper. 2️⃣ ON-TIME VOLUME PRODUCTION Manufacturing excellence is the other side of the coin. Bitdeer still has to prove it can ship on time and in bulk. They’ve already had one round of delays and reallocated units. They’re the only bitcoin hardware manufacturer I’ve seen refund preorders. Not a great start. Deliveries are now rolling, but a few weeks behind schedule. They also canceled their original hydro unit and jumped straight to the “Pro” hydro version, which should ship in June. So yes, some early operational hiccups. Caution is in place. (immersion: no information about those models yet) 3️⃣ TARIFFS Chinese-made miners are OK right now. They’re classified as computers, so duties are manageable. But Vietnam has an edge. Lower base tariffs and better US trade relations = fewer risks. That’s why Vietnam matters. Bitmain does the same by manufacturing some models in Malaysia, Thailand, and Indonesia. Bitdeer adding Vietnam contributes to global decentralization of hardware production. This is huge. This part of the story is bigger than most think. MOQs: most units are sold to large resellers, who then sell to retail. So contact your supplier (like us at Braiins Store) for more info. 4️⃣ BTDR STOCK Yes, Bitdeer is its own biggest client. They mine with their machines first. Same as Bitmain, but Bitmain isn’t publicly traded. Extra points for BTDR. That also gives Bitdeer an edge over other US public miners who don’t make their own hardware and rely on Chinese manufacturers. This introduces a whole new player into the public miners race. I’ll be watching BTDR’s performance closely. EXCITING TIMES 🔥 This is just the beginning. I’m not surprised others are just as hyped as I am. We’ll publish a teardown soon and share what we learn. Follow me so you don’t miss it. 🦭🦭🦭

Bitmain ruled for a decade. The monopoly ends today. Bitdeer's Sealminer A2 by is now shipping. This company was born inside Bitmain, is backed by Tether, and trades on NASDAQ 🇺🇸. Here’s the full story—and why it matters 👇 Bitmain has dominated bitcoin mining hardware since 2013 with Antminers. Founded by Jihan Wu and Micree Zhan, they built an empire—always the number one, holding 80% of the market to this day. No one comes close. But then came internal politics. Around 2019, the two founders started fighting for power. Classic case of “two roosters in one room.” By 2021, it ended with Jihan stepping down—taking some assets and business units with him. That’s how Bitdeer was born. A FORK OF BITMAIN. At first, Bitdeer focused on self mining, hosting, and cloud mining. Gigantic mining operations. Then in 2023, they went public on NASDAQ as BTDR. New capital for big plans. In 2024, Bitdeer announced they’d start building miners—including their own ASIC chips. So they acquired DesiweMiner (remember them?) A Chinese bitcoin ASIC R&D team. At the end of 2024, they promised their first flagship miner: the A2. Supposed to ship in Q1 this year. Slight delays, but… TODAY IT BECAME REAL. The Sealminer A2 is now shipping worldwide. 🔶 Hashrate: 220–240T 🔶 Power: 3630–3960W 🔶 Efficiency: 16.5 J/T ✅ Made in Vietnam—not China ✅ In stock—hundreds available now Prices are great and tariffs are low—it qualifies as a “computer,” so it’s import-friendly. Let us know if you want to try a few units, we now sell mini hardware too at Braiins. But there’s more to the story… TETHER INVESTED $150M. And got ~25% of Bitdeer. Remember that Tether made $13B profit in 2024. So we will see their influence grow across the entire bitcoin space. They’re the deepest pockets in the space—printing profits like no one else. So yeah... mining power dynamics are shifting. 🟠 Bitdeer is here with cash and experience. 🟠 Tether is buying influence right and left. 🟠 BTDR is a real contender with a real product. So WEN Braiins OS for 🦭? We just ordered a few A2 units for testing. We’ll take them apart, benchmark them, and see what’s under the hood. Can we port Braiins OS to them? Maybe. We’ll report back soon. Until then—watch this space. Because... Hardware is hard. But Bitdeer isn’t playing around. And more competition is always a good thing ⚡

The Bitcoin ASIC Queen said YES💍 Happy to announce the genesis of the Bitcoin Mining Power Couple. Of course I did it the most bitcoin way possible—and of course there’s a propaganda video coming

This illegal Bitaxe clone is quietly dominating Asia. Today I had lunch with the guy behind it 👇 He’s a young bitcoin entrepreneur from Shenzhen, China. Quiet, humble—but running a serious operation: large-scale self-mining, hosting, and full-scale manufacturing of mining hardware and spare parts. He’s been in the space since 2017. Genuinely believes in bitcoin’s mission. LuckyMiner started as a hobby in late 2023. He said he wanted to help more people get into mining—not really to make a profit. But in early 2024 the demand exploded. Thousands sold. BREAKING THE LICENSE. Bitaxe is open source under CERN-OHL-S-2.0—which means any modifications must be published. So why do it? I asked him directly. He didn’t get angry or defensive. He said: 1️⃣ Retail customers in Asia don’t care about open source, and the Bitaxe brand isn’t suited for the local market 2️⃣ His team is juggling too many projects—releasing modifications is low priority. Their time is too valuable Not great reasons—but they felt honest. 👉 Legit Bitaxes: They now manufacture open-source Bitaxes too—but only for B2B clients, fully license-compliant. LuckyMiners are sold direct to retail customers. 👉 Copying Braiins: They copied us too—and admitted it to my face. But that’s a story for next time. Follow me so you don’t miss it 😆 What’s next? As sales kept growing, they added a Litecoin version earlier this year. And they plan to keep expanding—with more form factors and higher production volumes. But he says chip availability is the biggest bottleneck. CHIPS ARE THE PROBLEM. Everywhere. Or rather—not having chips available for purchase is the story here for me. Hope we find a solution. Anyways… I don’t support his decisions. But I have to admit—he’s a really nice guy, bitcoiner at heart, and I appreciated his honest answer and perspective on the Asian market. Now you know the story behind the most controversial mini-miner on the market. Curious to hear your thoughts.

Six years ago I quit KPMG. Today I drove a Mustang through beautiful Oklahoma to a horse ranch where they mine bitcoin with flare gas and made another bitcoin video. This is my job now. Quit fiat. Join bitcoin. There is no second best.

You asked, we brewed more. ₿eer tour this month 👇 📍 Midland - Bitcoin Meetup | March 6 📍 Austin - Bitcoin Takeover | March 14 📍 Houston - Bitcoin Meetup | March 20 📍 Miami - Mining Disrupt | March 25

This is our non-Chinese bitcoin mining chip. And it’s a way bigger deal than you think 👇 Six years ago, when I joined Braiins, we had a mining pool. The world’s first. Then we launched custom firmware—now powering gigawatts of miners worldwide. Last year we dropped Braiins Manager. A cloud platform giving miners full control over their farms. BUT THE BIGGEST ISSUE REMAINED UNTOUCHED Hardware centralization. For years, Bitmain has controlled over 70% of the global market. And we’ve been loud about the need for competition. So instead of waiting, we built. This week, Braiins Bitcoin Silicon arrived in our Prague office. Our first test ASIC chips. 🫡 2.5 years of hardcore R&D. 🚀 Big skin in the game (shoutout to Firefish for helping us collateralize—not sell—our bitcoin 🧡). Exciting times, BUT… The work is just beginning. And it must be done. Join our mission!

In town for a week, my video plan: 1️⃣ Compass Mining service center tour - repair shop for ASIC miners 2️⃣ The bitcoin co-working place The Space with the Mining Heat Reuse book author Tyler Stevens 3️⃣ Chick-fil-A review with a local bitcoin guest star 👀 Any other ideas?
