Alt season will eventually come because there's always an altseason in every Bitcoin bull run, and there was a time that a particular altcoin made its own bull run in a bear market.
There's risk involved in investing in alt, but you can be sure of its own bull run when you have a proven alt in your portfolio.
Yes, there will definitely be a time for altcoin season. It's just that not all altcoins in alt season will be able to rise very quickly and skyrocket like other altcoins. And as you said, certain altcoins. and this is actually quite tricky for some altcoins that are not really the top ones. There are some old altcoins that have dropped very badly, such as ADA, EOS, LTC, and so on. Can this rise again during alt season?
Of course there is no guarantee. So, only certain altcoins can experience an increase, especially altcoins that still have potential, a high community, and also developers who care.
