The stupidity within Aussie Banks is huge. Please don't place any importance in the fact that they own CYB.
For all you know, they could holding on behalf of someone else (custodian), a managed fund using clients' money, or just some rogue trader leveraging up and taking a punt because he wants a massive bonus.
After all, it was an Aussie bank that bought this, mismanaged it and exited with billions of dollars of losses...
Far too many mis-alignments of incentive (conflicts of interest) to be even worth considering as beneficial.
