If the DAO hacker is part of the ETC promoter, then he might dump his ETC, but other big holders could dump/
Its gotta be the same guy. Who else would it be?
Some bitcoiners who invested in the bitcoin before. Some comments:

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.
