The reason I am optimistic about Steem is that it has the best community of like-minded people committed to success even in the middle of the crypto winter.
I am also enthusiastic about Steem because it has the best blockchain architecture combining immutable data with social consensus, while allowing great flexibility for user interfaces, app concepts and soft protocols.
Steem can become a perfect platform for business, attention trading, social web hosting, complex e-commerce systems and a lot more.
