Well, I believe that Steem is undervalued because of not many people speaking about it to the world outside of Steem world.
I personally try to promote Steem wherever I can and let people know about it.
This is the conversation of me with Nexo chat representative.
I will pass your feedback to our management.
I hope they consider this feedback and act on it. I did give them an invitation to make an account on Steemit too :)
