The price graph follows the typical alt-coin. Goes up sharply after launch for a quick pump, then people take profits and the price goes down all the way until the coin is dead.
Dont know why they had to go through all the effort to fork BTC when they could have just cloned it and started from scratch. It has the same result in the end anyways. I guess it was 1) to give a profit gift to the wide base of BTC community when they dump and 2) to enable data analysis of moving BCC to expose active corresponding BTC holdings.
For one thing, it was a way to spread out the distribution to a ton of people. Sure, a lot of people will dump most or all, but many people will at least save a little "just in case", so immediately you get a very large user base.
