As long as you keep interacting, posting great content, and curating, you'll get there. I went from 0 to 2000 in 8 months. 500 from a contest, but most of the rest came from earnings through activity. I bought some when it was nearly 1 hive/POB...I've bought some more here/there at 0.25-0.35 hive. I am still pondering on whether I want to build my POB or keep building my Hive Power. With Hive Power, I can invest, leasing it out to others. I can't do that with POB, that I know of...yet.
