These guys are quite wise, they sold the bitcoin before the hack and pump the ETC. It is quite suspicious.
I hope the DAO hacker and the Bitfinex hacker are not related. Bitfinex has reported to law enforcement. We might find out later.
It does not matter if they are related or not. The DAO hacker will not make much profit when the ETC collapses.
If the DAO hacker sells privately through multiple small accounts, we wont necessarily see him cashing out the millions as this whole pump has currently been taking place, your logic is flawed because you assume hes going to sell or transfer the whole amount at one time, visibly
