Good call, I came to the same conclusion - that people are buying up BTC to get their hands on some free BCC on August 1!
My question is, does it make sense to dump your BCC as soon as you can, or wait for the price to rise? I'm sure there will be a lot of BCC dumping, but I'm not so sure if there will be a price bump after that stage.
I'm pretty sure the price of Bitcoin Cash will be very volatile on August 1st. It's very hard to predict a good price for the coin.
