How to Purchase Cardano (ADA) Using POL (ex-MATIC) (POL) in China

To buy Cardano using POL (ex-MATIC), first, find a cryptocurrency exchange that supports the ADA/POL trading pair, such as YouHodler. Create an account, complete the KYC process to verify your identity, and deposit your POL into your exchange wallet. Locate the ADA/POL pair on the trading platform and place an order to exchange your POL (ex-MATIC) for Cardano. If the ADA/POL pair is unavailable, you can first exchange POL (ex-MATIC) 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.
