Even if OKX exchange only uses the wallet, any interaction records of the wallet address, IMEI, MAC address, etc IP， They are all centrally recorded. This is also an open secret in the wallet industry. Several old domestic wallets have made records, after all, it is too easy for the app to read IMEI and MAC, and RPC is centrally built and recorded clearly. If you use OKX exchange, it's even worse. Even if you do a good job of withdrawal isolation, OK has your KYC information with IMEI and OK Link matching detection business. I am a good citizen, but this feeling is too naked. The service relies on the robustness of the same company in terms of privacy, which is extremely poor. Even if the product is convenient, I would rather not use it.
