China hasn't banned shit except for centralized exchanges.
ICOs are technically still legal there if they register with their securities commission etc.
There are still buttloads of vendors on Taobao who accept BTC.
There are tons of Wechat/QQ groups where P2P trading goes on in fairly massive volumes.
China has fiat xferz with little to no chance of chargebacks making P2P exchanges a lot more secure.
What has caused a large percentage of the blip is Coinbase's bank no longer wanting to handle foreign customers' wire transfers.
Mm, yeah, this isn't the first time this has happened.
And everytime people lose their shit. Not really surprised at this point.
