You'll do well on my Machine Learning Price Prediction project.  (MLPP, not as easy to say as BPIP)  If you guess well, you'll have a provable stat and you'll be more likely to get investors to trust you.  Anyone can say they are good at price prediction, just like anyone can say they are in finance.   Price prediction can be a profitable career for you - you don't need 100% success - just more than everyone else.
