1. Sign up for Coinbase by making an account.
This first step is to sign up for a Coinbase account. This will give you a secure place to store your bitcoin, and easy payment methods to convert your local currency into or out of bitcoin.
2. Verify your account
After you sign up, connect your bank account. You’ll need to complete some verification steps before you can use the account. Once the verification steps are complete, you can start a purchase.
3. Buy Bitcoin
Go to “Buy” bitcoin, and select the amount you wish to purchase, Coinbase will complete your buy and deliver your bitcoin. (Sells work the same way but in reverse). The price of bitcoin changes over time, so they’ll show you the current exchange rate before you buy.
Note: You can buy any amount ($10, $20, $40), you do not have to buy a “whole bitcoin”
