How to Purchase 0x Protocol (ZRX) Using Hong Kong Dollar (HKD) in China

To buy 0x Protocol using Hong Kong Dollar, first, find a cryptocurrency exchange that supports the ZRX/HKD trading pair. Create an account, complete the KYC process to verify your identity, and deposit your HKD into your exchange wallet. Locate the ZRX/HKD pair on the trading platform and place an order to exchange your Hong Kong Dollar for 0x Protocol. If the ZRX/HKD pair is unavailable, you can first exchange Hong Kong Dollar for a stablecoin like Tether (USDT) or a fiat currency such as CNY, then trade that for 0x Protocol. Be mindful of potential exchange fees, which vary by platform and can impact the overall cost of your transaction.
