I  do believe bitcoin will be worthing atleast 30k-40k dollars at the end of 2018, but well my list is the follow:

ETH= 2000-3000 dollars
Ltc= 400-700 dollars
Dash=3400-5000 dollars
Monero= 1400 dollars
Iota= 80 dollars
Waves= 300-500 dollars

Into the end of 2018 it will be good to see wich coins will still around, because a lot projects and coins will get abandoned and will be forget, and the best thing is anything can help, this year bitcoin raised a lot and no one were expecting such.
