Why is your trendline upwards? I don't think a trending average extending from the initial pump is accurate.
All things remaining equal, the price should fall relative to the net buy pressure divided by the dilution, assuming an efficient market.
However the coin is so young, I don't think any price prediction is prudent.
I would not be suprised to see another pump when STEEM goes sub $2 or sub $1; by whomever backed this project in the first place.
