It depens. The bank can say we used xxxx etok for admins of exchanges and used xxxx etok for companies. But i can understand they wont name the admins or companies. We can do some recearch our self to see where the money went. But at they end its difficult and painstaking work to find out where it went(when its moving arround. Because admins or companies will spend there etoks) I supose that was also the idea of cryptocoins to be more or less anonymous.

So a general idea would be good enough for me. Its about trust.

And the DEV also must know that some people will dig deep. And if something is wrong it will be shown someday and be the beginning of the end. So i supose they know what is at stake here.
