could you please consider introducing the real price in FIAT for the respective crypto at the time of transaction?

The problem is, when I check my transactions on enjinx, I only see the actual real-time USD value of my e.g. ETH transaction. BUT I also would like to know what the FIAT value of my ETH was, when the transaction was performed e.g. 30 days ago.

This would make things also easier in terms of tax reporting.
