Now that etherscan has both ETH and ETC it is really easy to compare. So what are the whales doing. Dumping it looks like.
Check out accounts 9 through 23 on the first page, most have at least split, so possibly dumped, almost all their ETC. (We are talking hundreds of thousands of ETC per account)

Prepping for the massive dumps from the Coinbase ETC that will soon hit market once those withdrawals cut on.
Don't forget the 3m ETC in the attacker's DAO that will soon be available.
And the RHG could try to retrieve the 7m in the whitehat DAO.
Sucks that Polo doesn't allow shorting.
