Political differences is not the cause of the sudden dip, but Trump increase of tariff on all imported good entering the US. This didn't only affected bitcoin price but it also affected the stock market too. As a new investor that's is still in his accumulation stage, this shouldn't be our concern but to continue buying and keeping your weekly DCA ongoing because of this is an opportunity to buy bitcoin cheaper. I was lucky to buy $200 worth of bitcoin today that the price was at $75k+. Keep stacking.
I also bought bitcoin at $75k yesterday when people were panicking selling their bitcoins, we dare to buy better like that than we regret it a few years later who do not install bitcoins from now, coincidentally I always take the time to install Bitcoin with DCA and hope that in the next few years Bitcoin can become 150k-200k, continue to save bitcoins until you have at least 1 bitcoin for a better future.
