How to Purchase Polkadot (DOT) Using Basis Share (BAS) in China

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