I did it too! I am at my greatest steem power ever now so I can earn the maximum amount of return on my steem. The change in prices are nice, move a decimal point to the right on your payouts for the real price now :)
It makes one realize how deflated our real world currency actually is if it so easily tradable for our digital content.
Actually Steem dollars are valued at $1 US of Steem when they split the reward. So, say your payout is supposedly $11.70, 15% of that, about 1.70, goes to curators, $5 is converted to Steem Power at the rate of 1 USD to 1 SBD and another 5 SBD goes to you without conversion. So, you get about 5 Usd worth of Steem and $5 Steem dollars. So your rewardjs about 6x, not 10x.
Thanks for the most detailed calculation of this I have read so far. I was estimating but you are right on the money.
