Maybe its like this. Because the number of btc has lessen, the price went higher. On bcc, since it has few numbers, and the first thing they do is let the receive bcc the same amount of btc in it, based on internet. We don't know how much bcc has been in wallets as of now, they consider it as demand and maybe a lot of them are on the account, that's why prices go high because they think those are demand. Nice strategy to make.
