I had predicted a couple of months ago that Steem would be around 4USD by the end of the year. It is almost close to that now. I still feel that there is a lot of upside for Steem. I think all the growth till date is for the capacity of Steem to take care of rewards and ability to create apps on the blockchain.
While current leg of the growth will be driven by these apps gaining more visibility and companies which work on creating apps in steem blockchain the next wave of growth will be driven by Steem acting as a payment alternative to other coins like Litecoin, Reddit and Verge.
Everybody has have associated an image of Blog to steem network and hence they are missing out on the other usecases that it is fulfilling without creating noise. There will come a time when people will realise that and Steem will moon.
