Solo Bitcoin Miner with Just 6 TH/s Wins Block Reward Worth Over $265,000

A Bitcoin miner operating with only 6 terahashes per second (TH/s) has achieved an astonishing milestone by successfully mining a full Bitcoin block — an outcome so unlikely it’s comparable to winning a lottery. The miner earned 3.146 BTC in block rewards and transaction fees, valued at roughly $265,000.

The rare event was confirmed by Solo CKpool creator Con Kolivas, who noted that a miner with just 6 TH/s has only about a 1 in 180 million chance of solving a block on any given day. With the Bitcoin network’s total hashrate recently hitting a record 855.7 exahashes per second (EH/s), the winning miner controlled a microscopic 0.0000007% of total network power.

This block marks the 308th ever mined through CKpool since its launch in 2014, and the first successful one in nearly three months. CKpool enables miners to solo mine using the pool’s infrastructure while keeping the entire block reward, minus a 2% fee—making it a popular choice for hobbyists and small-scale miners hoping to strike gold against all odds.

The miner had been submitting shares normally, but with only 6 TH/s—roughly the output of a single older-generation ASIC—they would typically expect to mine a block only once in several centuries of nonstop operation. The extremely low probability makes this one of the luckiest solo mining wins in recent Bitcoin history. For comparison, in 2022, another solo miner running 126 TH/s overcame odds of 1 in 1.3 million to mine a block, but Friday’s achievement is considered even more improbable due to the massive gap between the miner’s hashrate and the overall network power.

As Bitcoin’s hashrate continues to grow, solo mining becomes increasingly difficult. The network gains security, but small miners face shrinking chances of ever capturing a block reward—making victories like this one both remarkable and inspiring to the wider mining community.
