Lightning Strikes Twice as Solo Bitcoin Miners Beat the Odds, Each Earning $300K

By Stacy Jones

Lightning struck twice this week for solo Bitcoin miners, with each of them earning roughly $300,000 worth of BTC.

Early Thursday morning, a solo miner landed a 3.157 BTC reward (including fees), worth roughly $304,000 at the time it was paid.

This was preceded by another solo miner successfully mining a block on Tuesday and earning a payout valued at $295,000. Instead, each miner received the full payout, a rare outcome given the dominance of large, industrial-scale mining operations.

The Bitcoin mempool is dominated by Foundry USA, AntPool, and F2Pool, which collectively account for nearly 57% of all blocks that have been mined.

Bitcoin mining is the process by which transactions are confirmed and added to the blockchain, the public ledger that underpins the network. Miners compete to solve a cryptographic puzzle using specialized computers, and the first to find a valid solution earns the right to add the next block of transactions—along with the associated block reward and transaction fees.

The process is probabilistic, meaning miners with more computing power have better odds, but outcomes are ultimately determined by chance.

It's not clear where the lucky solo miners are located, but there's evidence that America’s grip on Bitcoin mining is slipping.

U.S. Bitcoin mining firms have been racing to build infrastructure for artificial intelligence, which has resulted in several big deals. And even though that's helped buoy the share prices of the Bitcoin miners who have made the pivots, it has also provided an opportunity for countries like China to grab back market share.

In 2025, North American pools, where miners combine computing power to better their chances of solving a block and obtaining the block reward, saw a consistent decline in block share, or the percentage of total Bitcoin blocks successfully mined, according to a recent report from BlocksBridge Consulting.

As of December, BlocksBridge said that Foundry USA, MARA Pool, and Luxor Technologies accounted for 35% of all Bitcoin blocks, down from more than 40% last January.
