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.
