About the Bitmain Antminer S3
Is the Bitmain Antminer S3 profitable?
As of October 2026, the Bitmain Antminer S3 earns $-0.87/day mining Sha256 at an electricity cost of $0.1/kWh. At this electricity rate it is not profitable.
How does Sha256 network hashrate change Bitmain Antminer S3 profit?
When Sha256 network hashrate rises, your share of block rewards shrinks proportionally — the Bitmain Antminer S3 earns less even if the coin price stays flat. The simulator above lets you scale network hashrate up or down to model competitive pressure from new miners coming online.
What if the Sha256 coin price moves?
Block rewards are paid in the native coin, so daily revenue scales with price. Doubling the price roughly doubles the Bitmain Antminer S3's revenue — and because electricity is fixed, profit grows by more than 2×. The simulator above lets you set a custom price to model upside or downside.
