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 think investing in Bitcoin is the safest and most profitable of all cryptocurrency. And that's why investors are investing their money in Bitcoin. Because bitcoin is the king of cryptocurrency.
However, it cannot be said that altcoins have stopped. The prices of BNB, ETH, DOT etc altcoins have increased several times.
