Sure this is bound to happen because the contest is not with real money, and may foster the "go for broke" mentality. However, traders that do not do that are winning more and more. Watch the traders accounts that have been filtering up as the month goes by. You will start to see a few that actually trade pretty decently. They will win more and more in the future as other traders begin watching them more and more.
Take care, and good luck in your trading,
