The +27 number isnt yours. It is loaned to you while you are a minnow. I think at some point it is revoked.
If they hadnt delegated this tiny amount of steem power to you it would have made it near impossible to make any headway in the slightest.
Summary: not youra. U cant cash it out. At somepoint in the future...it gets taken back to the steemit pool!
Oh yes I remember now reading something about steem being lent to new users. Alright that makes sense thank you. I was seeing most users I checked out didn't have the second steem number. I'm a little minnow tho lol Cheers
