如何使用 Hedera (HBAR) 购买 United States Dollar (USD)

To buy United States Dollar using Hedera, first, find a cryptocurrency exchange that supports the USD/HBAR trading pair，例如 Nexo，或 Coinbase，或 Uphold undefined Bake. Create an account, verify your identity, and deposit your HBAR into your exchange wallet. Locate the USD/HBAR pair on the trading platform and place an order to exchange your Hedera for United States Dollar. If the USD/HBAR pair is unavailable, you can first exchange Hedera 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.
