I'm pretty sure about $30 for the year. Mithril is a STEEM ripoff (like YOYOW) but using ERC-20 and with focus on millennials. I've been following the project since the time you told me about Theta Token. I won't make any long term bets on it.

I hope for Hiveminds to come first. That will drive prices up like crazy and then a correction and then SMTs. What I found to be interesting was that they are working on what seems like HF21 along with SMTs and HF20

You can have an idea about SMT development here: https://github.com/steemit/steem/projects/5
It's not too comprehensive. But it's something and there is actual work being done.
