IYKYK

Finished another personal @BitcoinWalk yesterday: 38km around a North Sea Island, which is a small official annual hiking event organized by the locals. Lots of time to reflect on Bitcoin and where I see myself in the space moving forward. Doggo made it, too. #proofofwalk

"The secret of happiness is this: let your interests be as wide as possible." – Bertrand Russell Me:

I’ve been running my own solo mining setup for a while now – including a full node, a couple of #bitaxe miners, and a dedicated solo mining pool. Recently, I've automated miner monitoring and alerts with #openclaw. Running it on my Raspberry Pi and granting it access to Umbrel's OS, miner APIs, and hooking it up with Telegram turned out to be a super powerful combo. My agent now continuously keeps an eye on: 🔸 Bitcoin node: health and uptime 🔸 AxeOS: miner status and performance 🔸 mempool.space: network difficulty and newly found blocks Whenever a trigger event occurs, a Telegram bot sends an alert straight to my phone. For example: ◻️ ASIC temperature or error rates exceed defined thresholds ◻️ Hashrate drops below a certain level ◻️ New best shares (per miner and across the entire setup) ◻️ Miner or node goes offline or comes back online ◻️ Bitcoin network difficulty adjustment ◻️ A block is found by any solo miner globally ◻️ Or… by me (yeah, well) On top of that, I’ve set it up to give me a clean weekly summary every Sunday evening, including uptime per device, average hashrate, and more. All of this has been scripted and automated with OpenClaw and Claude Code, built in just a few hours, and on a $10 token budget. Mind = blown 🤯 @BTC-Solo-Mining

Personal 50k @BitcoinWalk: ✅ Definitely a valuable lesson in low time preference ⏳ #proofofwalk

⚠️ I don't know know who needs to hear this, but Bitcoin mining is NOT a "race". With Bitcoin recently crossing the "20M mined" milestone, I've seen a lot of posts across different platforms claiming that now the "race" for the remaining 1M BTC has started. This completely misses how Bitcoin mining works and reveals a fundamental lack of understanding of Bitcoin's predetermined issuance model. Referring to it as a race implies that participants in that race can accumulate more BTC in a shorter period of time by "running faster", i.e. that Bitcoin's issuance schedule can be sped up by putting in more effort. But that's just not how it works. 🟢 Yes, miners can spend more energy to increase their share in (and hence revenue from) all global mining efforts. 🔴 No, due to Bitcoin's difficulty adjustment mechanics the last BTC will still be mined around the year 2140, no matter how much energy is being spent along the way. Bitcoin mining is not a race, it's a slow grind. That's why we call it proof of work. Thank you for coming to my TED talk 🤓
