Not at all since bitcoin's market value is volatile that may fall and rise unexpectedly. It is actually a good timing for everyone who plans to invest in bitcoin if its market value will go down because it's really expensive to buy bitcoins now by just looking at the graph.
I am not also surprised if BTC's value went down a bit when BCH's market value was pumped up in the past few days because BTC is known to rise whenever it goes down.
