GPU mining is about done in China. It won't be long before police starts shutting down big mines, and then difficulty will drop.
They banned exchanges not mining.
Only trading against cny is banned.
Almost all mining hardware is china based, that alone will make sure they will not ban mining. Or maybe mining will only be allowed for government owned farms? (:
Yes, I would guess so. That means casual miners may be disconnected from the net.
ASIC mining of BTC/LTC/Dash is unlikely to stop since they are doing well. But for ETH, XMR, shitcoins or GPU coins, China doesn't make GPUs themselves so they might need a solid case about academic research, local economy or national security before mining them.
What they want from CNY exchange ban is to "control financial risk", or stop the money laundering craze and stop ICO scams. Once they realize that large mining farms can be used for money laundering they'll likely put the cuffs on it.
