I'm a newbee and this is my first post at steemit - maybe I did not get it - why should someone buy Steem if he can earn it by posting, commenting, and so on. What can I do/buy with a Steem? or is it just the speculation on a higher price?
I just did an upvote on my own post !?!

Oh, that'll be the day. If ETH and LTC can do it, then STEEM can too.
