How to Purchase Cardano (ADA) Using OpenEden OpenDollar (USDO) in China

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