How to Purchase Ethernity Chain (ERN) Using Cardano (ADA) in China

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