Why did Polkadot fall?

I've noticed a significant decline in the value of Polkadot recently. Could you please shed some light on what might be causing this downturn? Has there been any news or announcements that might have had a negative impact on the cryptocurrency? Or is it simply a market correction that's taking place? I'm curious to know your thoughts on this matter and whether you believe this trend is temporary or if there are underlying factors that might persist for some time.
