I am also wondering what is the force behind this sudden rise in price. It has been an awesome and massive profit taking for those who hold Bitcoincash. Good for them.
It's all quite transparent. You still don't know what is behind the quick rise in BCH exchange rates? Check this:

A few months ago - September. The whole reason people were pushing for segwit2x was because of the mempool backlogs. The bitcoin core people don't care about it though. They want people to pay higher fees.
