You seem to be confusing volume with liquidity. The question is not how many times a bitcoin (allegedly) changes hands on an exchange, but how many USD/CNY/JPY etc. are bidding on bitcoins right now.
Why wouldn’t the CNY/JPY/KRW markets have much higher volume when they have zero trading fees?
The magnitude of an exchange is measured by how many funds they have on deposit, not how often these deposits change owner according to the exchange’s internal database.
