Solo Bitcoin Miner Defies Odds, Mines Block Worth Over $300K

A solo Bitcoin miner achieved a rare feat by successfully mining block 883,181 on February 10, earning a reward of 3.125 BTC, valued at over $300,000. The total block reward, including transaction fees, reached 3.15 BTC, with Bitcoin priced at approximately $96,286 per coin, according to Mempool.space.

The miner’s identity remains unknown, but Bitcoin miner Marshall Long suggested they used an implementation of CKPOOL, possibly leveraging a Bitaxe device, which is commonly used for solo or pooled mining. This success is remarkable given Bitcoin’s high mining difficulty, driven by an increasing network hashrate, which stood at 788.86M on February 10—up over 53% from last year.

Solo mining is uncommon as large firms like Bit Digital, Riot Blockchain (NASDAQ:RIOT), and Marathon Digital (NASDAQ:MARA) dominate the space with massive hash power. Despite this, the miner managed to solve a block independently, securing the entire reward.

The event coincides with Bitcoin's price rebound past $98,000 following a brief market downturn triggered by U.S. President Donald Trump's tariff announcement on aluminum and steel. Although Bitcoin remains below its all-time high of $109,000 recorded on January 20, the cryptocurrency market shows signs of recovery.

This rare solo mining victory highlights the potential for independent miners despite growing competition, proving that even in an era of industrial-scale mining, individual success stories remain possible.
