Mr. Chen from Hangzhou sat in the police station, holding the freezing notification, completely stunned.
The day before, he spent 50,000 buying some coins in the C2C section of the exchange and transferred the money to the seller's WeChat.

Even more absurdly, the police freezing his account were from Hebei, thousands of miles away.
