HopeBook's money is on Smart Contract address where no one can attach to take money so the circle of support-receive will be forever. 

In case the amount of supporter is less than receiver, HopeBook still have 30% DCF token for community reversed fund. 

The token is sold for whole community, and once community provide big effort to raise the DFC token price, it brings benefit to both token's owner and HopeBook, where money has no change to run out.
