It is quite difficult to answer your question because there is a lot of speculation involved in such short period of time and i could not simplify all the thinking process in one simple post.
From a trading perspective i think BTC need to cool down a bit for few weeks before next moove up, altcoins deserve some love after a huge 6 months correction and it already appear on the BTC dominance index that investors redistribute some BTC value to altcoins.
Later in 2018 it is surely possible to see a new ATH for BTC.
