How to Purchase BNB (BNB) Using Open Custody Protocol (OPEN) in China

To buy BNB using Open Custody Protocol, first, find a cryptocurrency exchange that supports the BNB/OPEN trading pair. Create an account, complete the KYC process to verify your identity, and deposit your OPEN into your exchange wallet. Locate the BNB/OPEN pair on the trading platform and place an order to exchange your Open Custody Protocol for BNB. If the BNB/OPEN pair is unavailable, you can first exchange Open Custody Protocol for a stablecoin like Tether (USDT) or a fiat currency such as CNY, then trade that for BNB. Be mindful of potential exchange fees, which vary by platform and can impact the overall cost of your transaction.
