That is it. POB tokens are minted through the upvote botton. You either have to have authored a post (or comment) that got upvoted by someone with POB staked, or you yourself need to have POB staked and hit the upvote button.

So, I clicked the upvote button to your comment... and, since I have POB power... you have some POB coming to your POB wallet in 7 days. (as do I, as I get the curation reward).
