How to Purchase Polkadot (DOT) Using Echo Bot (ECHO) in China

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