Thank you for the great analysis of the STEEM economy!

(1)
You categorized 3,000 accounts into manual curation, bot, exchange, self support, etc. by role, and explained well how they own effective SP, liquid STEEM, SBD, etc.

(2)

Structure of the Steem economy: bots 15%, normal users 17%

I was surprised to see that the influence of bots, which account for only 1.5% (22 accounts), on the STEEM economy is almost the same as the influence of normal users, which account for 55.3% (1,658 accounts), on the STEEM economy.

So is the Steem economy healthy or sick?

I think it depends on whether we consider Steemit (1) as a coin staking system or (2) as a content platform like an online community or social media. :)
