Default Bitcoin Price Prediction Software

Hey guys, this is my first post here and I thought I'd share a project that I've been working on. I've been writing some software in java that uses an artificial neural network to predict the price of bitcoins. It looks at every transaction that has occurred since bitstamp was founded and I've gotten it to be able to predict prices within 24 hours with an average error of about 1.35% and prices within 5 days with an average error of about 2.62%.

I also made a website where you can see the predictions, and they are updated every hour (btcpredictions.com)

I would love to hear any comments, suggestions, or feedback that you guys have!
