Definitely, not all altcoins will go high, top 30-50 altcoins will rise. Bitcoin most definitely will go high in December, but I don't believe it will be as last year.
Not all of them, of course, some of the altcoins/tokens will cease to exist right before the coming of the bull run this year and it will happen with the unpredictable outcome on the 4th quarter or even on this present one, ATH is still achievable but it all depends on the crypto market, news and the community response.
