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.
Yeah, alts have been pumping alongside with bitcoin like doubled or even more, that's rare sighting in stock market and people still complain altcoin season not coming, it's either their standard of altcoin season is when alt go up thousands percent or they never see the market regularly. It's silly to be honest.
