6 billion $ in deposits simply vanished from several banks in China

Several news outlets reporting the scandal

Customers at a handful of banks in China are demonstrating . Their deposits have been inaccessible for several months. And it's looking increasingly like they got scammed. Their anger is being compounded by a chilling step the government appears to have taken to keep them from making noise.

This is what banks are capable of. One mistake, regardless if ill fated or accidental, can make your virtual fiat, poof away in a blink of an eye. And when the country in question is what it is, then you are really screwed.
