True, but if the BCH camp manage to pump BCH high enough to incentivise enough miners to mine it, the damage that could do to BTC could be a real problem. I expect that some of the big money wanting to get into Bitcoin for the long run would like for this to happen so that they could buy into a prolonged BTC bear market reaching down well below $5k, whereas others would rather get in before the end of 2017 for a more immediate rise to $10k-$20k.
Of course BTC wins long term, but whether we have to suffer another multi-year bear winter or not before hitting $20k is still unclear. I only hope that the battle for big money getting in inevitably results in a big money FOMO movement
Yes... transaction time will be the biggest risk. But BTC can definitely no longer afford to have a long 'winter' - if it does right now its dead. Even if BCH dies, regardless, money will flow back to gold/stocks and the credibility is lost forever, I don't think we will see 20k in bitcoin at that point - it will probably be remembered as atari when people will play with the new nintendo coin after a long time.
