I joined recently and yet to make my 1st post.

I made some upvotes and comments expecting some earnings to know and experience earnings method of crediting.
But nothing yet  as earned in my account.
My Steem power shows as  .......... 0.500 STEEM
                                            (+27.592 STEEM)
Is it anything related to earnings  from my activities [Upvotes/comments made]?

Any advice to get my 1st earning part in my account?
