When you buy a miner with hosting through Compass you will need to pay a monthly hosting fee for each miner. The hosting fee covers the electricity fee, facility security, customer service, and monitoring. The hosting prepayment fee covers the first month of hosting. After the first month, you will start receiving invoices in your dashboard.
The monthly hosting fees take into account the power draw of your miner(s). The more watts a miner draws the more expensive the hosting fee will be to account for the electricity fee associated with the machine.
The monthly hosting amounts are a flat monthly fee regardless of how many days are in the month. If there is any maintenance that results in extended downtime for your miners and they are not consuming power, a downtime credit will be applied. Learn more about how downtime credits are calculated here.
The hosting bills can be paid through your Compass Dashboard (fees are not taken from your mined BTC)
