At the beginning Blake said that Steem Power give you interest rewards. My understanding was that the only reward for holding Steem Power was the curating reward, I thought steem dollar give you interest ( 10%) but not Steem Power is that incorrect?
Blake also said at the end of the video that if you initiate a power down you stop earning the interest reward. I assume he is talking about the steem power balance building up. This is incorrect AFAIK, the extra Steem Power is still coming in after a power down.
