Ok, at first instance, it seemed to me to be the total winnings of a player but I've recently received $400 as my prize for winnings in a couple of contests & this was my first time receiving a prize, then why does my Contest Activity page say "Total Revenue 800 $"? What is that supposed to mean?
Total Revenue , means the total amount of money won by you in different contest that you attended. There is an eror in the Contest Activity. For example if you are nominee on the first places on which there are granted a prize it may appear in your Contest Activity. Once the Dukascopy valuation for the specific contest ends and for example you are entitled to that prize your sum will remain there or even increase but if you don't get any prize it will dissapear. I encountered this to.
