The matter of "Hangzhou's systematic investigation of crypto practitioners" seems to be a misunderstanding or self-delusion.
The original words of the OTC big shots in the group were: Since last year, Hangzhou has been conducting comprehensive checks on bank cards, and those with large amounts of deposits and withdrawals will be questioned, not just in relation to the crypto industry. Therefore, I advise all bosses to use fewer cards from the Hangzhou area for trading crypto.
