Generally DCMnetwork shows all conversion amounts in USD, but using the currency filter you can see the same amount (on each conversion) in your website-specified tracking currency setup on DCMnetwork.
Log into your account > Reports > Conversion report
Tick on Currency and Run Report
You can see the correct Currency in your Conversion Report.
NOTE: Please note that the currency filter will only show the currency setup as your "tracking currency" at the time of setting up your offer on DCMnetwork.
