I'm new in steem but the point is to define is something is a scam or not, we should try to find if the business add value to something or not. I mean, few comments before someone say it's not a scam I make a couple of $ with it...it's hilarous. Many people involve in ponzy scam at the right time make many $ and it's not because some people make money that it's not a scam !

So my question is simple if someone can help me to understand = Where does come from the money ???? What is the business model of steem ?

There is something in a white paper an explanation about how can they would try to monetize their platform ? For now I don't see on steem anything with ads...And I think it's the only thing that can bring fresh and real money in steem. Until they succeed to monetize their plateform, it's clearly a ponzy sheme. People are paid by other people that exchange their ETH against Steems... But it's quite ok for now because they are in Beta but if we can't see true development to find advertisors willing to pay for ads, it will be scary for the future of this plateforme.
