Keep your Bitcoin on exchange which give you BCC after fork and have BCC/BTC or BCC/USD is the fastest way if you can trust the exchange

Otherwise, send your BCC from your wallet as soon as fork happened with higher tx fees and sell it quickly after the transaction is confirmed or sell it later when the price rise if you think BCC can survive like ETC.
Even with high fees, it will take a few days to have 6 or more confirmations.
