How to Purchase Cardano (ADA) with United States Dollar (USD)

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