Good point. I think as time goes , steemit will grow in its membership and top social media, see my post about why Steem will take over social media:
At this stage, steemit will add more features in order to take advantage of demands ....this will include more buying and selling opportunities. Thanks for your post and following you for more and to send in my support.
