A solo Bitcoin miner has secured a major reward after successfully validating block 943,411 despite extremely low odds, highlighting the rare but possible success of small scale mining operations. The miner, operating with roughly 230 terahashes per second (TH/s) of computing power, earned 3.139 BTC valued at about $210,000.
Bitcoin Mining Odds and Network Share Explained
The miner was connected to solo.ckpool.org, an anonymous solo mining pool introduced in 2014 that allows miners to retain full block rewards minus a 2% fee. With only about 230 TH/s, the miner controlled roughly 0.00002% of Bitcoin’s estimated total network hashrate of around 1 zetahash per second in early April. This translated into approximately a 1-in-28,000 chance of finding a block on any given day.

The computing power used in this case is consistent with a small group of home-scale ASIC machines rather than a large industrial mining setup. By comparison, large listed miners such as Riot Platforms operate more than 30 exahashes of hashrate, making them vastly larger in scale.
Rising Pattern of Rare Solo Mining Successes
This block marked the 312th solo win recorded on CKpool since its launch and the first since Feb. 28, ending a 33-day gap. Over the past year, solo pools have discovered 20 Bitcoin blocks, distributing a combined 62.96 BTC, averaging one solo block every 18.7 days, with the longest gap lasting 58 days.
Similar rare wins have occurred recently. In December, a miner with about 270 TH/s overcame 1-in-30,000 odds to earn a $284,633 reward. In November, a miner running just 6 TH/s beat staggering 1-in-180-million odds to secure roughly $265,000. In late February, another miner converted about $75 worth of rented cloud hashrate into a reward worth nearly $200,000 after briefly directing 1 petahash of power to the pool.
