The problem as I see it is that the underlying causes of over-voting aren't addressed. Whilst there are bad-actors, I'm sure that most cases of this kind of abuse come about because people just don't get it. The highest rewards will come in the long-term due to a sustainable rise in the price of STEEM. Does the technology warrent a +$10b market cap, like etherium? In which case $45 STEEM is possible, but I'm sure we can only get there with some kind of a consensus on behaviour. Yes, I am optimistic, mostly, but there is a lot face-palming going on at this particular keyboard.
