Dolphins are definetely happier, minnows used to vote for each other, but now that their votes are worth more and lesser votes allowed, most will just vote on bigger fishes to get attention or even whales, or better still themselves.
If I could vote on myself and get close to $20/ vote, I am surely saving them votes on myself right :/
Only time will tell how effective this HF is, the way I am seeing, minnow's reward will get back into equilibrium at what they used to be making(maybe + a penny or 2) but for dolphins and whales. Them boost are real.
