I think 100$ is realistic for the shares.
Why are we talking about prices in dollars?
The target price I have is 0.1 BTC. I don't know anyone who is buying PTS with dollars. Over the year 2014 0.1 BTC will make sense. That could be between $100-$1000 depending on the price of BTC at the time.
0.1 would be awesome, i bought a few at 0.017 and will buy some more if the price dips lower than 0.014
As new DACs launch and are successful the milestone will rise. 0.1 is a good peak price for 2014. For 2015 it will be 0.2. For 2016 it will be 0.3. I don't see it going much higher than 0.3 because of competition but it could very well go higher depending on what happens with big business and institutional investment. I don't think any DAC is going to bring it over 0.3 but I think you could see it go over 0.3 if for example institutional investors really take to Bitshare derivatives.
Also 0.1 in 2014 is anywhere between $100-1000. It could be $1000-5000 in 2015 and beyond.
This is under the assumption that Bitcoin goes from $1000-10,000-100,000-500,000 over the next few years and these DACs attract Bitcoins to them at a certain rate.
When someone asks about the Protoshare price you can say they are deliciously underpriced.
Buying Protoshares now is like buying Bitcoins when they were $10.
