The price will most likely spike as people hear more about steem and it gets onto more exchanges. However, as people realize that there is no tangible value underpinning the price of steem people will sell and the price will continue to decline in accordance with the dilution of steem to pay of content creators and curators.
Steem doesn't entitle the holder to any revenue streem, so the value of steem is entirely subjective, making it impossible to speculate what the price will be in a year, a month or even a week.
It would be wise not to "invest" in steem, and instead just use the platform to find and post new information.
Let's just say that the STEEM user base will need to expand beyond the BitShares community. That group alone has not been enough to carry BitShares to wide adoption, even though the technology kicks other cryptos' butts. I also hope STEEM can be great, but we will need a lot more people involved. It's not just going to reach the moon because it's useful -- BitShares is damned useful and could solve a ton of problems people face in the real world, but still nobody knows about it.
May be we should open more categories for various discussions...
Why people will buy STEEM.
Keep in mind, part of the reward is in Steem Power which as you know must be divested over 104 weeks. That alone will keep people involved and interested.
