If China did ban bank accounts of exchanges, this would be the best thing ever.
1. BTC China and Huobi will be forced to develop exchange market based on individual bank accounts transacting with one another directly.
2. The publicity from the ban will raise people's awareness of bitcoin in china. People will try to understand what is going on and why the PBOC feels so threatened.
3. After the initial drop in price, people will realise that life goes on. The PBOC cannot succesfully ban everyone's bank account.
That would never happen, have you ever used banks b4? sound like some teenage's dream
It's called direct funds transfer.
