There are many ways to cash out of Bitcoin. I use the simplest and most convenient way, in my opinion. 1) Go to Binance.com and log in to your Binance account. You need to register if you don’t have a Binance account. 4) After receiving the desired fiat currency, go back to the Fiat and Spot wallet and click "Withdrawal ."5) Select the currency you want to withdraw and the appropriate withdrawal method. Use a currency converter to understand which currency is most profitable for you.
