When we choose the 50/50 payout option on our Steemit posts, we earn 37% more than with the 100% Steem Power payout because Steem Dollars or SBD are actually worth today $1.69 on the market! Would you continue reading to see why and how to quickly change SBD into Steem and/or any other cryptocurrency?
Here is the data from a recent post where we were kind enough to upvote it for these rewards.

That is what payouts look like on the default 50%/50% setting.

If I had chosen to power up at 100%, I would have simply received no SBD and instead double the Steem Power. I made a quick Microsoft Excel spreadsheet to show the differences.

With choosing the 50/50 option and using https://blocktrades.us/ to change Steem Dollars to Steem Power, I get 181.365 Steem Power out of my 227.888 SBD! The reason for this is that exchanges like Bittrex have Steem Dollars available to be traded which allows anyone to just buy Steem Dollars on the open market. Meanwhile, there are a very limited numbers of Steem Dollars available because they are only printed from rewards on posts as far as I know. This has caused the rate of exchange to Bitcoin and the USD to be as seen below today.

This means that while Steem pegs a SBD at 1 USD worth of Steem, trading it on the open market yields a value of $1.69 per SBD meaning that SBD today are worth 69% more than what they are intended to be. When exchanging for Steem, this consistently comes out to getting a lot more Steem with SBD versus just taking the full payout from Steem.
If when you see this SBD are worth less than $1 at https://coinmarketcap.com/currencies/steem-dollars/ then you might still want to get SBD anyway because you can use the wallet to make an exchange at the $1 value. Given that the Steem wallet will provide a guaranteed 1 SBD to $1 worth of Steem conversion, it is unlikely the price will ever go much below $1 for a SBD making the perfect scenario for SBD consistently be worth more than 1 USD. See inside the wallet for the options.

While I stated that I use blocktrades to change to Steem Power usually, Steemit has a market at https://steemit.com/market which lately has been much worse of an exchange rate than Blocktrades or Bittrex as seen below.

Changing my SBD to Steem on the market would have got me a much smaller gain than using Blocktrades or Bittrex to make the exchange.
In summary, it seems logical to consistently choose the Default (50% / 50%) option and to convert the Steem Dollars. I personally am using https://blocktrades.us/ to convert my SBD either to Steem to power up or to USD via Litecoin sent to Coinbase and then sold to my USD wallet. In the last month, I have powered up 3676.264 Steem using SBD and sold $3081.92 to USD for paying taxes and contractors like

I saw the Steem symbol next to Albert's post which means he powered it up 100%. I am not the first nor will be the last to post about this and I hope I have helped provide a quick tip today that helps you make a lot more off of your posts you were considering on powering up!
