Unless you can clearly explain, in small words that even I can understand, HOW you are getting the bitcoins to pay interest I'm going to assume that this is Yet Another Ponzi Scheme.
I understand how SatoshiDice makes money, and I have no issues with them generating lots of transactions.
If you were CHARGING interest then I would understand, and would have no issues with your service.
So: how will HungerCoins make money? And don't answer "I can't tell you or everybody else will do it," that is the Ponzi-operator's standard answer.
