Small setups, big wins: Is solo Bitcoin mining making a comeback?

Key Points

1. A solo miner recently won block 907,283, earning 3.125 BTC (~$372,000) plus $3,436 in fees, demonstrating the potential for solo mining success.

2. Modern ASIC miners, like ASICKey's KEYMINER A1 (1,100 TH/s at 650W), enable solo miners to compete more effectively with higher efficiency and profitability.

3. Despite improved ASIC efficiency, the odds for solo miners remain low—1 in 650,000 per 10 minutes for a miner with 1 PH/s of hashpower.

4. Solo miners are motivated by the possibility of large rewards (6.25 BTC + fees) rather than predictable income, contrasting with pooled mining strategies.

5. Foundry USA dominates Bitcoin mining with 29.3% of the hashrate, highlighting the prevalence of centralized pools despite solo mining successes.
