My prediction would be heavily relient on the outcome of the whole segwit 2x drama. I expect a fork but from there I don't know what to expect at all. Since bitcoin's weekly chart is looking extremely parabolic, I'm expecting a drop to around $5400-5500. If that happens the lowest price will be our support level going into 2018.
If, in 2018, we are able to integrate lightning network we could very well hit $10000 around may.
