TL;DR:
A solo Bitcoin miner turned a tiny machine into a lottery-sized payday after validating block 957,382 with a single Bitaxe rig. The miner received 3.125 BTC, worth about $200,000, despite using hardware that costs less than $200 and runs at about 1 terahash per second. Another report put the total payout at 3.1382 BTC once fees were included. The win is remarkable because the equipment is almost symbolic, a credit-card-sized device competing inside a global industrial mining network.
The odds make the story even stranger. The miner reportedly ran the device for only eight hours through Public Pool, averaging roughly 995 gigahashes per second, or about 1 TH/s. That hash rate is a minuscule fraction of Bitcoin’s total security budget, where large operators deploy warehouse-scale ASIC fleets. The Bitaxe uses the Bitmain BM1370 chip found in Antminer S21 machines, but consumes only 15 to 21 watts. This was not efficient scale beating competitors, it was statistical luck arriving in public view.
Still, the episode is not completely isolated. This was the second time a single Bitaxe has solo-mined a block on Public Pool. Hobby-level miners have validated 12 Bitcoin blocks so far in 2026, including one through CKPool in April and another in February using rented hashrate. Over the past 12 months, solo miners have found 24 blocks, up 41% year over year, collecting 75.4 BTC, or about $4.7 million, in total rewards. The payouts remain rare, but they are no longer invisible.
That visibility lands while industrial Bitcoin mining faces pressure. Mining difficulty dropped 5% to 127.17 trillion on July 12, after falling more than 10% in mid-June before partially recovering. Large miners continue dealing with compressed margins, and some have shifted toward artificial intelligence data centers and related infrastructure. Against that backdrop, a $150-style rig earning a six-figure block reward feels almost absurd. The episode does not rewrite mining economics, because solo mining remains closer to a lottery than a business model. But it does remind the market that Bitcoin’s proof-of-work design still leaves room for improbable participants, even as professional scale dominates the industry. For hobbyists, the appeal is participation plus impossible upside, not predictable revenue, and this block made that appeal unusually visible again this week.
