Being new and seeing this for the 1st time I was wondering what it's all about too and what happens when I click it!

So I've clicked it and see the rewards have been added as Steem Dollars. I was wanting to build up Steem Power, so do you know is it best to do this straight away as you earn it or are there exchange fees etc and it's best to wait until you have a larger amount?

Thanks for your post!
