The DAO bugfinder (which you unjustly call "the thief", he played by the rules that were written on the ethereum and DAO website: the code is the law) has 10% of ETC.  But 90% if the ETC is held by people that had ETH from before the fork.  Their dumping is much more dangerous than that meager 10%.  On the other hand, you've got 30% or so of probably very disappointed DAO bagholders on the ETH chain.  Aren't you affraid they'll be looking for the door as quickly as they can ?
