On this page, I will try and simplify setting up your account, and buying Bitcoin, Litecoin, Ehterium, and Bitcoin Cash
Step 1. Sign up with Coinbase! In order to buy Bitcoin(BTC), Litecoin(LTC), Etherium(ETH), or Bitcoin Cash(BCH), you will need to create an account with one of the exchanges. These are currently the only 4 coins that can be bought with USD and a credit card. (Technically, there is a few other sites that allow it, but I am not a fan of them). The most common exchange is Coinbase. Click here to create an account then come back to this site to go to the next step! It is pretty straight forward to sign up. Enter email, state, basic info. You will need verify your information by uploading a picture of your drivers license. This isn’t as hard as it sounds and doesn’t take too long. You will also need to add a payment method (credit card and/or band) to buy BTC.
Step 2. Buy some Bitcoin! Once you have Coinbase set up (there is also a mobile app) and set up a payment method (I just used my credit card) you can buy some crypto. You can buy it at market price right through Coinbase or you can also use GDAX (owned by Coinbase) which is more advanced, but will let you create an order, in which you can sometimes get a better price.
Once you are logged in, click on Buy/Sell at the top, enter how much you would like to buy and hit purchase! It can take some time for it to go through. I have seen it take an hour. If you are paying with a bank account, expect it to take a week or so for the entire process.
