There is a misunderstanding going around the community that because of the segwit2x the price dipped, it has nothing to do with the fork happening as this is not the real segwit2x but a clone. For most of you'll who are not aware, South Korea is mulling strict actions against Bitcoins and that's been another negative news for the crypto king, though there's lack of clarity what action shall take place, it was a blow as Korea is a booming market. Hence there was a fall, and the happening of the fork was just a coincidence.
