Hello,
I've done this a few times to make a bit of extra Steem, But it can be risky. Throughout my time of being on this site (Almost 2 years) I have found that the price of Steem is usually higher than the price of SBD.

The goal with SBD, Is to keep it "pegged" At 1.00 But lately It's been a lot higher for some reason. SBD, Can be compared to our USD. Because it used to only be worth 1.00

The recent surge in price in both SBD and Steem, Has caused the internal market to be a little weird.
usually those numbers you are seeing in the market, Could be as high as 2.00 or 3.00 ! But because the price of SBD is so high, It has driven them down.
So be careful. I think there is a chance that the price could keep rising in our market.

To Power Down

1. Go to your wallet where it says "Steem Power" Then click the arrow down, And click "Power down".

You have to wait 1 week for these funds, And you'll get them in increments of 13 based on your power amount.

Now if you wanted to completely withdraw the money and put it in your bank account, That's where it gets more complicated. And I can find a tutorial for you later when you are ready to do that.
