When the steemit say to buy Steem, I still do not think why we should buy it, I have to recommend to advert to the community here at least they could have done BID to advertise their posts, so they have a reason why people should buy it Steem order get visitors from other communities and regain profits from Upvote will they get here, I think it looks pretty fair for all
