# Types of Quantum Machine ![](/files/kpp6oL9DB9NC2E3vD02m) The quantum mining machine produces USEC Tokens. The higher the price of the Quantum machine, the greater its ability to produce USEC Tokens. A % of USEC Tokens will be swapped to mint EC Tokens. When a new series of Quantum Machines is introduced, the existing machines are discontinued. The new series comes at higher prices but produces lesser USEC Tokens. Buying the current Quantum Machine gives you the opportunity to keep it for personal use or resell it in our C2C stores to other players after it's discontinued. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
