How to Purchase yearn.finance (YFI) Using Cardano (ADA) in China

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