Under the hosting model, miners are immediately delivered to selected hosting facilities. These miners are already on their way or located in the hosting facility. Clients gain remote access to control the miner and receive KASPA coins or Bitcoins. We handle hosting, maintenance, and servicing of the miner, with hosting locations near power stations utilizing green energy sources. The profitability of miners in hosting is typically higher than self-hosted miners. Clients can choose to relocate the miner from hosting to their location or have it delivered to their address with a three-month notice period.

In the delivery model, clients are responsible for the miner's care and maintenance. In the hosting model, we manage the miner, including service and maintenance, for a small fee covering electricity charges and service fees.
