If you need to cash out, there are basically two options for how to exchange the Wrapped Fibonacci into a Brazilian Real. First, you can swap it peer-to-peer with a person who's interested in buying Wrapped Fibonacci for fiat money. Generally, this option is more anonymous, but it is also less secure. Second, you can sell Wrapped Fibonacci on specialized crypto exchange platforms such as Binance, Coinbase, Crypto.com or FTX.
