Could #Steem end up at $0.00?

Yes, it could. Most of the Steem blockchain users are selfish and greedy. They focus only on their own posts, and they do not care about other people's posts. Nowadays the real human comments are rare on the Steem blockchain. Even if people write comments, they often write bot-like and spam-like comments to get attention to their own posts. This led/leads to many disappointed users, who left and still leaving Steemit and the Steem blockchain. This platform is doomed by its own users.
