Sign in on coinbase with your credentials to start your first Bitcoin buy.
Once you are logged in , click on the large green button “Add payment method”
Now you will see a screen similar to the screenshot below.
The green button “Add payment method” is marked with red and once you click that button the popup should appear “Add account”.
Here, you can choose between bank account and credit/debit card.
We go for credit card since that is what this article is about.
