By the end of segwit2x integration then price will start to drop. We call this a "Correction" move .
Altcoin prices will gain from this drop. First drop will be around 6500$ then we will see a deeper correction to 5600$
If we get some more sells then we can face a deeper correction to 4500$ and this will be the end of correction move.
Ethereum price will be rise again 0.07 BTC while this happens.
And here we will start a new bull run which will possibly start around 14-December 2017.
This bull run will not stop until we hit 10.000$ and this will be the begining of huge rise.
After this we will see that bitcoin suppport line will place around 6500$
