We will never be reach via shitcoins?
If you hold mostly with that portfolio it's hard to recover for you whether there is or there is no altcoin season.
This cannot be true, if the asset is greatly underestimated one day it is sure to redeem, create the appropriate news background, raise the price and sell it - it always was.
But as btc dominance increases, most alts will be affected.
Everything can happen. In 2017, nobody believed that Bitcoin would reach 10 thousand and it managed to jump so high, that in some countries, people were ready to buy BTC even more than for 21 thousand.
Later, when it fell critically and we were in a bloodbath for a long time, a rare person had a hope that a market would recover. The so-called altcoin season will come, but no one knows when.
