A solo Bitcoin miner utilizing an affordable, compact crypto mining rig has successfully solved a block on the blockchain, earning a substantial reward of $263,000.
This miner became the 297th solo contributor to successfully mine a Bitcoin block from the solo.ckpool Bitcoin mining pool, as noted by the developer on March 10 in a post on X.
The miner operated with a Bitaxe machine capable of 480 gigahash per second (GH/s). For context, many large-scale crypto-mining operations utilize machines with capabilities exceeding 230,000 GH/s.
“A miner of this capacity has less than a 1 in a million probability of uncovering a block in a day’s time, which translates to an average of 3,500 years needed to find a block,” the developer remarked.
The miner collected a total of 3.15 BTC for successfully solving block 887,212, which was timestamped on March 10 at 7:22 PM UTC. This includes the standard 3.125 Bitcoin mining reward plus an additional 0.025 Bitcoin from transaction fees, as indicated by mempool.space data.

A more powerful Bitaxe Gamma 601 machine, which operates at 1,200 gigahash, is priced at approximately $158, according to cryptocurrency miner marketplace ASIC Miner Value.
This source estimates that the Bitaxe Gamma 601 would generate a bit more than $20 per year while consuming around $18 worth of electricity, resulting in a minimal yearly profit of under $3.

It is reported that the likelihood of the Bitaxe Gamma 601 successfully mining a block solo on any given day is one in 4.6 million, or one in 12,700 over the course of a year.

It is uncommon for solo Bitcoin miners to successfully solve blocks, especially those using smaller mining rigs.
The majority of Bitcoin is extracted from large pools like Foundry USA, which sources a significant portion of its hashrate from public Bitcoin miners such as Cipher Mining, Bitfarms, and Hut 8.
The largest publicly-traded Bitcoin mining enterprise by market capitalization and hashrate, MARA Holdings, operates its own mining pool, MARA Pool.
While compact Bitcoin mining solutions tend to lack profitability, there’s a push towards developing open-source micro miners to counteract the “secrecy and exclusivity” prevalent in the Bitcoin mining sector, shared “Skot,” a builder of Bitaxe miners, in a September 2023 discussion.
Many Bitcoin miners, like those manufactured by Bitmain, are closed-source, which contradicts Bitcoin’s fundamental principles, Skot argued.
“The rise of these open-source projects aims to highlight this frequently murky field, fostering transparency and making it more accessible to the public.”
