Right now the price of steem is about 1.64 while sbd is 1.28.
Now is a good time to earn more sbd because steem is 1.3 times more valuable.
That means that you shouldn’t power up just yet. Instead convert your earned steem to sbd as you will get more back- 1.3 times more.
So if you had 2 steem you would get 2.6 sbd in exchange.
