I found you can hold USD on BYER without a bank account connected. This is great if many people use it as we can have liquidity to protect ourselves when altcoins have bad periods.
Does anyone know any other exchanges ages that are more liquid and let you hold USD. Does BTCe?
I doubt if that is a good choice to hold your money on bter or somewhere else longer than necessary.
Remind yourself of the last hacking tries on Mt. Gox for example.
