Then probably this is one of the reasons why the price of Steem is low nowadays. Many people are not confident in Steem. Me neither, as the real human interaction on the Steem blockchain is so rare nowadays that the Steem blockchain feels like a ghost town. The average number of comments per post is only 2-3.
