Some general advice. CSV of trading action has very little to do with source of funds. They are interested in where you got the fiat to buy the crypto in first place. That's what source of funds means. You have that data so show that to them and show them the movement of those funds to the exchanges. Then you can add on the trading activity data and you should be covered in principle.
I'm currently living in Portugal but I did some trades a few years ago in my country of origin. Do you reckon there is any chance Swissquote could leak the source of funds + trading activity documents that I will provide to my country of origin? I guess the answer is no, but just want to be extra cautious.
