Excellent post and i did like to add one more thing, it's true the blockchain produce new steem that didn't exist before just like gold miners dig and produce new gold which not exist before, so as gold produced with proof of work same case with steem, steem also created with proof of work, so steem follow the gold mining concept, it is not produced out of thinhere actually the creator's create new content and then new steem produced on basis of how useful the content is, thanks for sharing your nice thoughts with us, Stay blessed
