Probably mostly the demand for it.

"Having the confidence of the user is vital for a currency."

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. Most of the people are focusing on their own posts, but they do not care about other people's posts. Most of the users are dooming the Steem blockchain with their selfish and greedy behavior.

By the way, take a look at Uptrennd. That website gives entirely different experience. You get more comments than upvotes on it. That is a real social network. The real human interaction is real on that website.
