If that's how you feel you too should participate in the release of BCC. Crashing the market would be particularly easy for all bitcoiners holding any amount of Bitcoin. In contrast, people owning BTC only to not participate would have no direct impact on the market as they would not influence supply. In my opinion speculators are more likely to show little support to BCC if the launch is met with a horrible crash but then again a recovery wouldn't be too unlikely.
