If a monitor is connected, it can become a regular computer where a user can open a browser or play their favorite video game.

The rig is connected to the internet, and thus, the blockchain network. The network operates by itself to conduct monetary transactions using the power of the graphics cards. To be more specific, a mining rig consists of:

  • An ordinary motherboard, which has the capability of linking to a number of connectors for GPU cards.
  • A hard disk drive, or HDD, with 100 to 250 gigabytes of memory to house the cryptocurrency wallet, with an Ether wallet usually taking up 25 GB and a BTC wallet requiring 50 GB or more.
  • S ...
