Why does it take 30 minutes to pump?

I'm curious, why does it often take approximately 30 minutes for a cryptocurrency's price to surge significantly? It seems like such a precise time frame, and I'm wondering if there's a specific reason behind it. Is it due to certain trading algorithms or patterns that emerge during this period? Or is it a result of market participants waiting for a particular signal or news event? Could you elaborate on the factors that might contribute to this 30-minute pumping phenomenon in the crypto markets?
