In addition to what @blocktrades said, once rewards start, you will also earn additional steem power, so you don't necessarily need to buy more to get to 10x, you can earn them on-site too.
Payouts for writing and upvoting posts are paid in another currency called STEEM-backed dollars which you will be able to sell whenever you want and you don't have to buy anything to earn them. These payouts are scheduled to being on July 4th for all the posts you make before then. The easiest way to make money on STEEM is to post some popular content, especially if it's original content, and let others upvote it. The first payouts could easily be the highest payouts, so you've joined at a great time.
