All altcoins die every year until Bitcoin is resurrected. 
When Bitcoin is in a bear season, the market is also in a bear season. When the market is in a bear season, there is no altcoin that diverges positively from the market. This may be the simplest explanation for how the market works. Actually, there is no need to be pessimistic, but coins other than major altcoins are never safe.

Old coins will die (except ETH and a few others), while new ones will take the reigns as the "next big thing" in crypto. Bitcoin is the main trigger of the market, so if BTC prices go up, altcoins will do the same (or the opposite if BTC goes down). You have to consider that altcoins have a lot more risks than Bitcoin itself.
If you know how to play your cards right, then altcoins make the perfect "tool" to grow your investment in the short term. Otherwise, I'd suggest you invest only in Bitcoin to play it safe. The crypto market often comes with surprises, so who knows if you become the next crypto millionaire by holding prominent coins for quite some time? Just my opinion
