If you have an active subscription to Premium, you can download the transaction history for any address as a CSV file (a spreadsheet). The history goes all the way back to 2018 and includes all blockchains and networks that Zerion fully supports. You can find the list of fully supported networks just here.
You can use this CSV file to prepare taxes or analyze trading performance (not just yours but of any address).
