I also like the way steemit has intermingled block chain with a content platform. However, it has got its own challenges and would be interesting to see how it evolves with time. Many of the content sharing platforms like Hubpages that used to reward users are in trouble because they could not change with time.
RE: Why I´m claiming that STEEM is the most promising cryptocurrency of the present & especially the future?! (Some of many facts!)
