How to Purchase United States Dollar (USD) with Polkadot (DOT)

To buy United States Dollar using Polkadot, first, find a cryptocurrency exchange that supports the USD/DOT trading pair. Create an account, verify your identity, and deposit your DOT into your exchange wallet. Locate the USD/DOT pair on the trading platform and place an order to exchange your Polkadot for United States Dollar. If the USD/DOT pair is unavailable, you can first exchange Polkadot for a stablecoin like Tether (USDT) or a fiat currency, then trade that for United States Dollar. Be mindful of potential exchange fees, which vary by platform and can affect the total cost of your transaction.
