Well, I don't have any data to show you but I do belive the value of a social plataform depends heavly on how many people want to use it.
Think about it: there is no ads, no value creation besides the content posted which is not sold to anyone. So, where the actual value comes from? Like any other currency, from the adoptions and trade utility. Both will not grow if the reward system still the way it is. And I know it because all those minnows trying to change this reward system is the only data I have to think about steemit, maybe not enought to convince you, but still something you should consider.
If things stay the way they are, steemit will soon become a small and valueless plataform for early adopters/investors scratch each others back. That's the right time for steemit to learn and improve or resist and probably die. That's the main reason I am not willing to invest more than the 500 usd I alredy invested on steemit.
