To sell bitcoin using Bitstack:
Tap the Wallet tab on your Bitstack app
Enter a custom amount or press Max to sell all your bitcoin
Select one of your linked bank accounts or add a new bank account (you can link a new bank account or manually add a bank account by entering your IBAN)
Press Sell to confirm
Note: When you sell bitcoin, Bitstack instantly converts your bitcoin into euros and automatically initiates a wire transfer to send the funds back to your bank account. It then takes 1-3 business days to receive the funds.
