In my opinion, seasonal changes have no effect on increasing markets. because the market movement knows no season. because market conditions are volatile.
I think it does . if we look on the past price history of the cryptos we can see that every 3rd and 4th quarter of the year are the best time for cryptos because in these period crypto prices are skyrocketing but this isnt fix or theres still no guarantee that it will occur on every year because if we look on other year like for example on the year 2018 , we can see that cryptos didnt pump but instead they remain stagnant at the red zone .
