SageMaster currency

SageMaster is beeing offered to european customers and we have a strong community in Europe. Their main currency is EUR, so it makes sense to not only show the assets in USD or BTC but rather have an option to use EUR as well.

To not mess with UI/UX this could be selected in the user settings to be changed instead of having 3 buttons with 3 different currencies (USD, EUR, BTC).
