It will never happen. Bitcoin is the king. Bitcoincash is pumping because of some news and whales out there. Also because of the fork tomorrow. It will never happen that Bitcoin cash will take over BTC. Trust me. I trust Bitcoin all the way.
This.
There was a long period of stable, low pricing that allowed whales to accumulate on the DL. The sales pitch by the whales is the same in the wake of Segwit2x: 1) if approved, it signals that BCH is part of the future, and 2) if failed, BCH is the future. Either way, there would be a run, and gazillions of $ to be made.
Oh, to be a whale....
