I've written numerous predictions on bitcoin's price in these threads:

I can prove unmatched ability to predict it's movement (I use unique machine learning algorithms).

Currently wondering if I should continue using it for my own profit, or is there anything to gain from creating a service?
A profit from a service would have to be significant in order to be worth it, so i'm wondering how much would people pay for it?

You can see my predictions in realtime now - I am SHORT on bitcoin right now (Current price in bitfinex is $11,550). Watch the price as it drops soon.
