I don't actually do long posts but I just had to read this to the end. There was so much to learn.
I agree with you on all points, especially the use case. Cryptocurrency (or any form of exchange) gets its value from what need it can meet and Steem is meeting so many needs:
- Stimulating quality posts
- Changing the way we understand social networks
- And create a steady wealth for many.
I'm never selling Steem (and Dash, although it didn't make your list)
