we may not be able to speculate whether price of bitcoin will go up or go down because of all the drama that will come by the end of this year but we can say one thing for sure:
when bitcoin price falls, altcoins follow its trend downwards.

so far the only exception has been altcoins are are in their start of pump. for example if they are pumping an altcoin and it is a couple of hours into the pump when bitcoin starts going down, that particular altcoin won't be affected but the rest will fall too.
