To be honest my 2018 goal of 14,500$ is what i expect as a minimum what it will reach.
I think so because we have grown ~100 billion$ in the last 12 months and the whole crypto  thing is just at the beginning like the internet was in the mid 90's.
WHEN it really goes mainstream - and thats what i think it will do - 100 billion$ is nothing! (look at apple, their market cap is of close to 1000 billion$, and thats only one single company!)
So as you see im positive for the whole crypto thing, maybe another coin will be the leader in the future but i think in the next years it will be bitcoin, no matter about the fork.
Even if bitcoin2x will be bitcoin later, everyone will get the same amount he has now in bitcoin - so you cant miss it if you dont sell too early...
im really sure we will see more than 1000billion $ for the crypto market in the next  years!
