Chinese OKX answers with fee, funding and liquidation calculators.
BlankVar (币中有数) is an independent Chinese-language tutorial and calculator website for OKX and Web3 beginners. Its question-based guides explain deposits, withdrawals, account records, fees, wallet safety and liquidation rules, with source links and verification dates. Free calculators estimate spot trading fees, perpetual-contract funding payments and isolated-margin liquidation prices from the reader’s inputs. Content and tools are freely accessible; the site discloses OKX referral commissions and does not handle exchange accounts or execute trades.
