I really enjoyed this post. I actually just wrote about all 3 of these coins and I will include the link at the end of this reply. I think Steemit is the gateway to the newbie, Bitcoin is the stable state that you wish to attain after gaining some knowledge, and Ethereum is for the tech heads who want an advance degree. I think it is great that Steemit may end up a non-technical/simple rival/competitor of Bitcoin. Cryptocurrency needs a friendly entryway or a killer app that gets newbies hooked- Steemit may be the answer!
