Steemit out of steam? A Sincere dummy question.

This is not clickbait! I honestly want to dig this. What are we looking at? Could somebody explain? Is this a problem if the downtrend continues?
Steemguru's... Hive account@ned Hive account@dan Hive account@steemit Hive account@berniesanders Hive account@blocktrades Hive account@ben Hive account@smooth... please feel free to step in with your educated answer.
I still don't understand the relationship between the 3 different tokens inside steemit.
Is there a tutorial for dummies?
