First of all Steem is a cryptocurrency really different from the others, more involving the community than any other currency which is , I consider, as a force. Moreover the money has only been registered since 18 days and its marketcap is already nearly at 8 million $, so if you want my opinion I think its going to do just like with Ethereum I guess It will reach the 8-9 dollars per Steem in 3 months and probably 100 $ in a year as more and more enterprises are getting interested with the crypto-currencies so the people will get interested in and the price will skyrocket
