A $300 home miner just hit a $250,000 Bitcoin block reward — but the odds are still brutal

A solo miner using a machine with roughly 6.5 TH/s of hash rate mined Bitcoin block 973,413 on Oct. 27, earning a 3.14 BTC reward worth just over $250,000 at the time, according to public data from CKPool cited by PANews. Altair Tech said the device was likely a Canaan Avalon Nano 3S, a compact home miner that sells for a few hundred dollars and draws 140 watts of power. The report places the win in a broader pattern. PANews said similar low-power devices also landed major solo mining rewards earlier this year, including another Nano 3S on May 30 and a Bitaxe Gamma on July 10. Even so, the article stresses that these cases remain statistical outliers. Using the network difficulty of 140.58T and estimated global hash rate levels around 1,000 EH/s, the report calculates that a single Nano 3S would have an annual chance of roughly 1 in 2,900 to 1 in 3,200 of mining a block. The piece also links growing interest in home miners to pressure on industrial mining economics. It cites falling hashprice, weaker fee income, and rising difficulty, while several listed miners have shifted power capacity toward AI-related business lines. In that setting, small home miners are being marketed less as profit machines and more as low-noise devices that combine hobbyist participation, occasional pool income, and household heating.
