To convert cryptocurrency back into traditional currency, you typically need to use a cryptocurrency exchange platform or a digital wallet that supports the conversion to fiat currency. You can sell your cryptocurrency on an exchange that allows fiat withdrawals, and then transfer the proceeds to your linked bank account. Alternatively, you can use a peer-to-peer platform to find buyers willing to purchase your cryptocurrency with traditional currency. It's important to consider the fees and exchange rates when converting cryptocurrency back into traditional currency.
