We predict the price of the BTC from 3 data sources:
1) The BTC Sentiment Analysis on Twitter in real time.
2) The search hits on Google in real time from BTC, and
3) The weighted mobile average of the price of the last 5 quotes of the currency.
We obtained an accuracy of more than 90% in predicting the price 8 minutes before.
If you need proves I will be happy to provide them.
