Offline older miners and hashrate
Hashrate you bought or tested stays on that generation. It cannot move to another generation for free. An Offline generation does not add rewards until it is Online again. On the dashboard, each generation on your account, and each one for sale, has a miner card.
Online, Warmup, Offline, and Retired
- Online: it is running, and the card shows Mined, Power, and Reward. Power is the electricity.
- Warmup: it is being prepared. There are no daily rewards yet.
- Offline: it is not running, because mined bitcoin would not cover the electricity. There are no daily rewards.
- Retired: it is not brought back.
You can still buy hashrate, or start Free Testing, on an Offline or Warmup miner. The miner can stay offline. The TH stays on the miner while the status changes, and daily rewards are added again only when it is Online.
An Offline miner moves to Warmup, then to Online, if mined bitcoin would again exceed the electricity and the pool fees. There is no date for when it comes back. The hardware is retired, and it is not brought back, if rewards would not cover the electricity and the pool fees for three consecutive months.
Electricity credit
Electricity credit is USD you can add once the account already has hashrate. On the dashboard it is labeled Power credit, and it is not hashrate. You cannot sell it or transfer it, and there is no payout of it. Free Testing cannot buy it. It does not turn an Offline miner back on, and it does not change Warmup.

Newer miners
Hashrate already on a generation stays there. To add TH on a newer miner, use Buy Hashrate and pick one that is for sale. Automatic scaling buys the newest, most efficient miner for sale, the one with the lowest W/TH, and it does not add hashrate onto older generations. A paid efficiency upgrade that would move old TH is planned, and it is not available yet. Whether you can sell hashrate is in Can I sell hashrate?.
