Hey there just farmed some coins, but have a question, can anybody explain this to me?

I think there is something going wrong, or am i wrong?
Of course, there will be a transaction fee, but there are all coins allready mined... Who should mine Zetacoins, when there is a reward for only one Coin? Pooled mining will die...
Regards
Pseyco
All coins not mined. ZET has a built in 1 mil per year inflation after the first 160m
