Currently, the currency is stored in the rate. This does not make sense, as there might be different rates. I don't know of any tariff that is billed in different currencies.
Therefore, I suggest restructuring it into a place where it states the currency only once per tariff.
We could also create a validator that validates that there can never be different currencies per tariff.
