Hive account@kenhudoy, the answer to the first question is published in another comment.

As for the second question, Hive account@sophtcodr has indeed published a nice link to our product description: https://rados.io/posts/what-is-rados

The difference between steemit and rados is that steemit is a finished platform that won't see any new development (Dan Larimer has moved on to work on EOS), and Rados will keep getting better with each product update. The two platforms also have a different audience focus. Steemit is more about general discussion, like poetry and music (although crypto is still the biggest topic), and Rados will be exclusively about cryptocurrencies and different analysis techniques. We want to share our analytical approach, and we want to learn from the community how you pick cryptocurrencies to invest in.
