Solo Bitcoin Miner Beats 1-In-28,000 Odds, Pockets $210,000 Block Reward

A solo Bitcoin (BTC) miner running roughly 230 terahashes per second (TH/s) of computing power, a level consistent with a small stack of home-scale ASIC miners, validated block 943,411 on April 2 and collected 3.139 BTC in block subsidy and transaction fees, worth approximately $210,000 at the time of the win, according to data from block explorer mempool.space.

A terahash is one trillion hash operations per second, the standard unit of Bitcoin mining power. A hash is a single attempt to solve the cryptographic puzzle that validates a Bitcoin block. The miner was connected to solo.ckpool.org, the anonymous solo mining pool introduced in 2014 that lets operators keep the full block reward minus a 2% fee, in this case, approximately $940.

The 230 TH/s setup represents approximately 0.00002% of Bitcoin’s total estimated network hashrate of around 1 zetahash per second (ZH/s) as of early April 2026. For comparison, listed miner Riot Platforms runs more than 30 exahashes, which is roughly 130,000 times the hashrate of the solo winner. At that share of network hashrate, the miner faced approximately 1-in-28,000 odds of finding a block on any given day, according to CKPool developer Dr. Con Kolivas, who announced the win on X.

The block is the 312th solo win recorded on CKPool since the service launched and the first since February 28, ending a 33-day drought. Statistics compiled by independent tracker Bennet show that solo mining pools have found just 20 Bitcoin blocks over the past 12 months, paying out a combined 62.96 BTC, roughly one win every 18.7 days on average, with the longest gap between wins reaching 58 days.

In a separate development, a second solo miner scored a separate block on April 3, meaning two independent solo Bitcoin miners won consecutive days in a row, an unusually tight cluster for a mechanism that typically produces one winner per three weeks.

The wins arrive against an institutional backdrop that has moved sharply in the opposite direction. MARA Holdings announced a 15% workforce reduction as part of a strategic transformation. Riot Platforms sold 3,778 BTC in Q1 2026, according to a Thursday release, joining MARA, Genius Group, and Nakamoto Holdings in a wave of miner sell-offs amid tightening margins and worsening market conditions.

Solo mining remains a statistical long shot by design. The probability compounds unfavourably with every difficulty adjustment, and the next one, projected for May 2, 2026, is expected to cut current difficulty roughly in half to 67.46 terahashes following a sustained average block time of 20.60 minutes against the 10-minute target. When it lands, it will reset the odds and the lottery runs again.
