impossible since I don't invest in things that are not clear to me. No whitepaper can convince anyone that money flows through the air and everybody both curators,investors and content publishers get money.
I was pretty optimistic for Steem, because I thought advertisers would be the ones to pay the bill, but so far I don't see much going in that direction.
So if any Steemians can point me to something that proves me (and snowboard789) wrong, please do!
