Deposit /withdrawal fee structure on bter for cryptocurrencies was quite complicated due to historical reason, different fee structure for different currencies.
To make it simple, bter has adjusted its fee structure. For any cryptocurrency, there is a bonus of 1% for deposit, and a fee of 1% for withdrawal (plus the fee for transfer currencies via networks when withdrawing, which is different for different crypto-currencies)
