Also know that as some people are buying the dip, the market might fall for further which might not be good at all for altcoins because they are more volatile. But you can buy the dip if it is bitcoin and less volatile coin.
In my opinion if bitcoin falls further it will encourage altseason to start, because people will get bored with the movement of bitcoin and it will encourage a lot of money flow will go into altcoins
If you keep an eye on the market, you will know that when the price of Bitcoin falls, so does the prices of altcoins, so if people are going to get bored of the movements of Bitcoin, the same should be the case with altcoins as well. So I see no logic in this statement where you said that people will start investing in altcoins and leave Bitcoin alone which will bring an alt season because no matter what happens, people will still believe in Bitcoin more than altcoins.
Personally, I don't believe in altcoin seasons because I believe most of the altcoins move with Bitcoin and the season that most people call the alt season is basically also the Bitcoin season because I have never seen any altcoin have a higher 24h volume than Bitcoin, and this proves that there are always more investors interested in Bitcoin than altcoins.
