Great post explanation!
I'm confused about the ratio of Steem to Steem Power. If I try to buy Steem or Steem Power from blocktrade, it appears 1 BTC will get me the same amount of Steem or Steem Power. (the get estimate result). If there is a conversion rate in powering up, this shouldn't be the case. Shouldn't I be able to buy more Steem for 1 BTC if 1 Steem Power is equal to multiple Steem? (current steem_per_mvest = ~ 223; mvest = SP).
