I had a similar situation in the US when I sold some Bitcoin before making a large purchase. To avoid getting confused in the process, I first looked at the instructions at https://paybis.com/withdraw-bitcoin-to-bank-account/, which explain how to transfer BTC directly to a bank account in dollars. This helped me understand the sequence of actions and approximate costs. After that, I prepared my bank details and made the conversion without any unnecessary steps. This approach is convenient when you need US dollars for official payments and large purchases.
