We will only witness an altcoin season once the season for bitcoin has no longer dominating in the market. Which means, if bitcoin turns bearish, altcoins will be the one to face the bullish season.

However, when bitcoin drops its price, altcoins will eventually follow. They follow whatever the path of bitcoin is. Those who stay on the downward trend and fail to recover, they will no longer be a part of the altcoin season, only those who have surge high after bitcoin falls.
