I went through the whole process of setting up an account on Coinbase because it was supposed to be cheaper by using your bank account. You have to enter all your account/routing stuff and wait for them to make two small deposits and then u have to verify it. Then u can buy bitcoins at the current rate and they are deposited into your Coinbase account where you can them use to purchase. Just know it’s not a quick process. After you purchase it takes 17 days to clear before you can use them. I have about 7 days left. Just purchase enough to buy what you need. It’s ok if you buy more than you need cause if you want you can sell your bitcoins buy depositing them as cash back into your bank account. Just remember the hold time before you can use them so u have to plan ahead. It’s about a 20 day process when u first open it.
