How to Purchase Optimism (OP) Using Hong Kong Dollar (HKD) in China

To buy Optimism using Hong Kong Dollar, first, find a cryptocurrency exchange that supports the OP/HKD trading pair. Create an account, complete the KYC process to verify your identity, and deposit your HKD into your exchange wallet. Locate the OP/HKD pair on the trading platform and place an order to exchange your Hong Kong Dollar for Optimism. If the OP/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 Optimism. Be mindful of potential exchange fees, which vary by platform and can impact the overall cost of your transaction.
