It is probably another pump and dump scheme by big investors or another attempt to replace the original Bitcoin, and what I found in an article that this co-founder of the website bitcoin.com Emil Oldenburg said that he sold all his Bitcoin to buy more Bitcoin Cash because the fee is too high and he wants investors to do the same (spreading another FUD lol), I don't know if it's true and how much Bitcoin he has but if he holds big amount of Bitcoin maybe it is also the reason why Bitcoin price drops a bit now, but surely it won't last long and BCH will fall back soon.
