BTC survives the challenge from BCH, then rises, unchallenged. Leaves the operating trend, embarks on new trend, defined by slope of the crash.
Today's price momentum is above-median, for trend, can assume a slower-growth rate and still remain within bounds of its existing trend.
Right now, the only challenge to BTC's price is its resilience to crashes. Literally, its only challenge is its ability to remain bought by the market, and survive doubt in its value.
Today my mother-in-law expressed amazement at the price of BTC. Her sole source of news is mainstream/ Today-show sources. When the grandmas are enthused by BTC, they may-well find a way into the market, or ask their advisors for a way into the market.
