If the blockchain is not reversed to block 7000, then the most rational behavior is to dump all mined/bought coins relatively quickly. If not, then due to this error, all early supporters and miners will have been diluted into oblivion. Also, if the total issue of coins is still at 1 billion, the miner reward will have to decrease drastically, and for lot of people there would be no incentive to mine CWC. In addition, you have no assurance that this kind of thing would not repeat again, so if you let the post error coins stand, you are only assured that they will live by the next fork whenever that happens. So why keep those coins and not exchange them for something more established that would keep value?

The team should let us know if the total number of coins and mining rewards will now change.
