China won't ban mining..even if they do..mining will continue behind the shadow.. China always end up having too much electricity surplus which gets totally wasted..mining firms use those surplus electricity.. This recent ban was just one of their strategy to control the price.. In China the price of dollar is set by the government, it doesn't work by demand/supply.. They want to do the same with bitcoin.. But due to this big endorsement by Japan, it appears like China's strategy failed.
