Bitcoin Miner Beats One-in-Ten-Million Odds to Find Block Worth $347,000, Raising Questions About Solo Mining in 2025

A Reddit user claimed to have mined a Bitcoin block solo using an Umbrel Mini, earning $347,000. Blockchain data confirmed the claim, but solo mining is still unlikely in 2025 due to the dominance of large mining pools controlling 75-85% of global block production. The chances of a solo miner finding a block are around one in ten million.
