You can use the CryptoWallet exchange to trade cryptocurrencies or convert funds to and from fiat currencies like EUR and GBP. Log into the CW app, visit the exchange, and select the account you want to exchange currencies from. Then choose the desired amount and confirm the transaction. You may need to enter a 2FA code if 2FA is enabled, and this will be sent to your device. For more information on how to exchange currencies, navigate to the exchange menu.
