Solo miners have been defying the odds, winning full Bitcoin block rewards despite high network hashrate. Last week, a solo miner earned 3.125 BTC worth over $372,000, plus $3,436 in fees. Modern hardware efficiencies are key to their success, with ASICKey’s models delivering high hashrates at low power draw.

Efficiency is crucial for solo miners, with ASICKey’s KEYMINER A1 offering 1,100 TH/s on Bitcoin at just 650 watts, generating monthly profits around $1,200. Their hardware line includes the KEYMINER X and KEYMINER PRO, delivering up to 5,800 TH/s at 2,800 watts with monthly returns of $6,300 for the PRO model.

Despite improved ASIC efficiency, solo mining remains a lottery. A miner with 1 PH/s hashpower has a 1 in 650,000 chance of solving a block every 10 minutes at current network hashrate. Some miners go solo for the chance of a big reward, while others value decentralization and independence from centralized pools.

US-based Foundry USA dominates Bitcoin mining with 29.3% of total hashrate, followed by AntPool, ViaBTC, and F2Pool. A single or few pools controlling over 50% of hashrate could launch a 51% attack, eroding network trust. More solo miners with clean energy and efficient hardware could lead to a healthier, decentralized Bitcoin network.
