I don't think it's like that bitcoin and altcoin will go up side by side even though the number will still be more in bitcoin.
but at least as long as bitcoin dominance does not exceed 70%, altcoins will also continue to rise along with the rise in bitcoin prices.
The movement of altcoins depends on bitcoin. all the direction of the increase that occurs is determined by bitcoin. this is a sure thing. because the dominance of marketcap which is almost 60-70% in bitcoin, if there is an increase or decrease in altcoins will follow. for now I think if you analyze it is better to compare with the bitcoin chart other than the altcoin you choose
