Today, the Hong Kong Securities Regulatory Commission issued the rules for the supervision of virtual asset exchanges. In the detailed rules, the CSRC requires the platform operator to ensure that (or its associated entities) store 98% of the customer's virtual assets in the cold wallet, and the hot wallet storage assets do not exceed 2 %. Moreover, platform operators and their associated entities should minimize the transfer of assets from offline wallets that hold most of their virtual assets. Once a hacker breaks in, investors often have difficulty recovering losses. The CSRC will require platform operators to ensure that the insurance they purchase is always effective. In addition, all hot wallet assets should be 100% guaranteed, and cold wallet storage assets should be largely protected, for example 95%.
