What do you exactly have in mind? I mean, what you don't understand? Maybe I can help...
If you are an author here, you earn STEEM and CTP from your posts. Got payments after 7 days, CLAIM your rewards and if you want exchange tokens/coins to FIAT money and buy yourself something nice :)

If you are curator (upvoting others and earn money by doing that), you can buy CTP (or STEEM... or both) and STAKE some of the tokens, upvote others, after 7 days you will receive rewards for doing that... :)

Win-win!

Thanks for your comment... ;)
