Can I sell hashrate?

You can't sell hashrate back, transfer it to another account, or redeem it for USD or BTC. Support can't sell it for you either. Payouts of mining rewards use your BTC payout address.

What a purchase is

A purchase is a rental of SHA-256 mining capacity on mining hardware. You don't own the machines. The hashrate stays on the generation you bought, and that miner adds rewards while it is Online.

The machines can't be sold, rented out, or moved to another generation for free. A paid efficiency upgrade is planned, and it isn't available yet. How an older miner comes back is in Offline older miners. A purchase is final unless the law requires a refund.

How long hashrate stays active

Hashrate stays active only while mining rewards exceed the electricity and the pool fees. There is no minimum operating period. Net rewards from an Online miner are the mined bitcoin minus the electricity, and that net is added to pending payout.

Your BTC payout address

Pending payout sits on the dashboard, next to the miner cards. Enter your BTC payout address on that card, and check it before you save. Later payouts use that address. The payout runs once pending payout reaches the minimum, and network fees can apply. If you set Automatic scaling to Off, or to 0% when Advanced mode is on, future net rewards stay as pending payout. Automatic scaling doesn't sell hashrate.

If you deactivate the account

You have 30 days to log back in and cancel the deactivation. After those 30 days the account is closed: your pending BTC payout is sent to your BTC payout address in a final payout, and all hashrate is removed. The hashrate isn't sold, and removed hashrate isn't refunded unless the law requires it. Account deactivation and closure explains the details.
