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.
During the period of bitcoin price growth since December last year, most altcoins have also appreciated well in price. Therefore, there is a prospect for the development of altcoins. Bitcoin will not continue to rise in value. After a while, all the same, its growth will stop, and then it is most likely that capital will begin to flow from bitcoins to altcoins. Therefore, I think that we will still see the altcoin season.
