Very interesting concept! I love to follow the markets and charts, and I certainly enjoying a little trading as well. I honestly do more buying and holding, hoping that my research will eventually pay off. Time will tell, I guess. This app is very interesting in many regards and could be quite fun and helpful for those that trade/want to trade. The concern I would have is about how the app monitors Tweets. As we have seen in social media and in mainstream media at this point, I worry about rumors and other market sentiments that could sway and effect buying through this app. Just my two santoshis. Thanks, as usual, for an awesome and informative post! -Respect
