I wonder the same thing. If the database was corrupted then what will they do with the money in their wallet?
They should make regular backups of the database and keep it in a safe place. How do you think they do it? How many Gb can a database weigh?
I wonder the same. They must have a backup system to avoid this. It is strange that many accounts have happened to them and other accounts have not. In the end, we can only wait for responses from support; they will say what happened or maybe they will not tell us anything and scam us as it has happened when the bitcoin balance disappears and we never have answers about it
