If coinsmarkets wants to exit, why go throw the pain of changing the host, the problem is not with the database, but with dev staff that can't
correct the corrupted data, i think coinsmarkets can't return the system to the point where it was coherence.
I think they should fix the DB up to a certain point and open the trade again. Keep the data on a separate entity. Once users start lodging tickets for missing transactions you deal with it on a case to case basis. The longer they leave the site offline. The more issues they are running into.
