DHF has some funds (x) to spend every hour, it goes from top to bottom (votes count) until x = 0.
If it will reach my proposal having x > 0 then my proposal will get all what's left (amount is really big enough for that) and send it back to DHF.
Currently however, HBD stabilizer proposal has a daily pay so big that it eats what's left from x, so neither gamification proposal or return proposal are funded.
