Open trading account 
1) go to the table "Trader Contest / Trader contest leaders" and choose "Equity leaders"
[or go directly: http://www.dukascopy.com/tradercontest/?action=standings&type=equity_leaders]
2) choose "Show only active traders"
3) click on "Min. EOM equity" to sort the data
Now look and see how many traders have cumulatively this:
Months of participation > 3 +
Min. EOM equity ≥ 50 000.00 +
Average EOM equity > 100 000.00.
Only a few, isn't it? cause is very difficult to archive something like that in this kind of contest.
well, I think this kind of contest participant also deserves a prize when we talk about "consistent long-term trading results". just an idea
