Frequently asked
About the Obelisk SC1
Is the Obelisk SC1 profitable?
As of October 2026, the Obelisk SC1 earns $-1.20/day mining Blake2B at an electricity cost of $0.1/kWh. At this electricity rate it is not profitable.
How does Blake2B network hashrate change Obelisk SC1 profit?
When Blake2B network hashrate rises, your share of block rewards shrinks proportionally — the Obelisk SC1 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 Blake2B coin price moves?
Block rewards are paid in the native coin, so daily revenue scales with price. Doubling the price roughly doubles the Obelisk SC1'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.
