With the stratospheric rise of Bitcoin the altcoins should move big time as well.
But they do not and will not move, as all the institutional money is pouring into bitcoin.
We won't see a "year of the altcoins" for a very long time, at least not before bitcoin has reached one million.
I dont think that it is true cause upon observing the pattern of every bull runs, it is always true that after the bitcoin domination, altcoin season will follows.
