First of all, thx for your good post. However, I think there are some flaws in the accumulation of each currency in your MODEL: It would be as follows:

1. Steem:
   Buy (with Bitcoin)
   Convert with Steem Dollars
   Power Down (from Steem Power, in 104 recurring months)
   Transfer from another account

2. Steem Dollars:
   Convert with Steem
   Earn via creating Content on Steemit (%50)
   Transfer from another account

3. Steem Power:
   Buy (with Bitcoin)
   Earn via creating content on Steemit (50%)
   Earn via curating Content on Steemit
   Earn via being a Witness (Mining) on Steemit Blockchain
   Power Up (from Steem)

Pls be kind to reply to me if you don't think my MODEL above is right. I am also a newbie and don't want to start with the wrong foot.

Thx in advance and regards,
