How to Purchase Polkadot (DOT) Using Bidao Smart Chain (BISC) in China

To buy Polkadot using Bidao Smart Chain, first, find a cryptocurrency exchange that supports the DOT/BISC trading pair. Create an account, complete the KYC process to verify your identity, and deposit your BISC into your exchange wallet. Locate the DOT/BISC pair on the trading platform and place an order to exchange your Bidao Smart Chain for Polkadot. If the DOT/BISC pair is unavailable, you can first exchange Bidao Smart Chain 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.
