Why has the altcoin marketcap been bearish during the summer season?

As I explained it yesterday, I think the main reason is BTC halving months.

Crypto total 2 marketcap(Excluding BTC) has been boring until October or November in BTC halving years.

I assume the main reason is BTC halving years. BTC dominance tends to be strengthen in BTC halving years so far. As long as the BTC dominance indicates strong, It shrinks weak hands' altcoiners.

Alright, let's take a look at the past halving schedules.

2nd BTC halving schedule: July 2016
3rd BTC halving schedule: May 2020
4th BTC halving schedule: April 2024

What's the common thing? BTC halvings have occured in the early summer or summer. So, I think it's not coincidental that the altcoin market has been bearish during the summer.

I don't want to make this kinda mistake in 2025 when this cycle will likely finish 🙏
