What I do not understand is: Even if the 51% attack had been fully successful, how did the attackers think they will be able to liquidate 9.7m CSC? Surely, their objective must have been to illicitly gain the CSC and then sell them for BTC and walk away with the BTC. Given the historic market depth, that seems nigh on impossible without crashing the price to zero.

So, something is fishy here. Why would an attacker go to such lengths only to end up, even in the best case scenario, with 9.7m CSC that are practically unsalable?

Unless of course the attackers were insiders and had other motives, such as taking over a large part of the coin supply.

Don't speak without knowledge of the subject, ... if there is any insider it would be Cryptopia themselves as they required the CSC dev team to deposit 9,7 mln coins or they would delist CSC. We offered to look into replacing the involved users BTC instead of CSC as we do not have any reserve CSC available as CSC does not have a premine. Cryptopia refused that so they are at fault here and i do not react very well to threats! Until now only 1,8 mln coins have been reported missing by users so i wonder where the other 8 mln is??

All malicious transactions are rolled back on the blockchain within acceptable timeframes and could take place because Cryptopia had only 6 confirms on deposits and works only on their own internal DB instead of verifying against the blockchain. The attacker got users BTC and run off. To stop all speculation you can find all transactions below with their rollbacks from a primary CSC seed, ... you can check that in your own debug.log if you run your own full-time online CSC node:
