GUIDE HOW TO BUY BITCOIN in COINBASE

Step 1 : Go to https://www.coinbase.com/, and Sign up
Here is what you need before get started :

+ A valid photo ID (such as a driver’s license)
+ A bank account or credit card

A minimum account size is not required at Coinbase; you can buy bitcoin at Coinbase and then ship it to your private wallet, leaving a zero account balance at Coinbase if you like. Perhaps the safest way to hold bitcoin is in your own private wallet, in case the exchange gets hacked.

You will need valid identification, such as a drivers license or photo ID. Some exchanges require a selfie of you holding your identification card. You will upload your ID directly on the Coinbase website. For security purposes, Coinbase does not allow you to send your ID by email.

You need a bank account or credit card. During due diligence, Coinbase will send a few pennies to your bank account, then you must verify the amount to Coinbase. All this is for verification and authentication purposes.

Step 2 : To buy Bitcoin, scroll up to the top of the main Coinbase page and click on Buy/Sell. A screen will pop up that looks like this :

 

You can specify a dollar amount of bitcoin you want and the website will display the amount of BTC you would receive for that amount. In this case, the purchase is for $200 worth of bitcoin or 0.01369407 BTC.

Hit “Confirm Buy.” Then you will see a green check indicating the purchase was successful.

Return to the dashboard and there will be a summary of the account and its activity, including the purchase of $200 worth of Bitcoin.
