Hey there! You need to use an ERC 20 compatible wallet or the Essentia app wallet http://app.essentia.one. "The Essentia app also now supports hardware wallets. You can use two devices - Trezor and Ledger - to access Essentia. In this video, see details on why hardware wallets are important and see how to use them": https://bit.ly/2K4PqHi

My personal recommendation would be to keep your ESS tokens in a hardware wallet like the Ledger Nano S.
