You can rund the XEP Desktop Wallet in parallel (at the same time) on different computers. This means you can put a copy of your PC wallet, for example, also on a Raspberry Pi. A Raspberry Pi mini computer consumes a lot less power than a traditional PC. This is a preferred method by some users to avoid running their Desktop computer 24/7 in order to participate in the XEP staking process (to keep the proof-of-stake network running).
