All those new folks entering the space who are enamored by the Bitcoin name could get caught hodling a bag of stink. It doesn't matter if it has the name Bitcoin if the technology behind it grinds to a halt because there's a mass exodus to the Bitcoin Cash side. And last time I checked, the word "Bitcoin" is still in the name of Bitcoin Cash.
Time is a funny thing in the cryptosphere.....it doesn't take long for enormous shifts and movement to occur rather quickly.
