If money come from your personal bank account then your bank account is the source of funds, right? But they want to see how you got your money in a bank account? Will bank statement work in this case where incoming transfer is visible, for example if you get payments from Google Adsense or something like this. What documents are listed in the form?
When in liquidation mode, is it possible to convert currency (if you hold USD convert it to EUR or vice versa)? Because, for example, SEPA payment can be sent only in EUR, not USD.
I'm confused. You didn't get the request for information but still want to know? If you did, why not log in and take a look.
I'm not sure about currency conversion, typically it's considered a trade. They might not care about SEPA and expect you to make a regular wire.
