Will renew this domain

I bought this domain last year, and now it’s about to reach my 12 months using it that’s why I am quite thinking of if I will renew this domain out or not, help me to decide please. Actually I don’t even earn over this blog now becuase the blog hasn’t have any page rank at all at this moment but I hope before this domain will expired then google will give me such good page rank so that I may not allow this to get expired then, hopefully google will update by this first week liked what theyve been did last year April updates. Let see if this happen, I’ll make an update over this blog again pretty soon.
