I write for the finance and investment website ValueWalk. My post entitled How To Buy Bitcoin: A Guide For Beginners is now online. Here is an excerpt:
First, the Wallet
You’ll need a wallet. Not a nice leather billfold, because Bitcoins are not physical. There are no coins and no paper bills involved. It is all virtual. The Bitcoin wallet is an app that you can download to your phone, and your computer. It contains two 16-digit passwords: one is called a public key, and the other is a private key.
Quite simply, when you buy Bitcoin, your wallet sends your public key information to the vendor, the same way you would enter a credit card number into an online form. The public key tells the vendor’s app where to send the Bitcoin amount. The private key is the password you employ to confirm the transaction from your end. This one-time code is reviewed by the computers on the blockchain, who then approve the transaction unanimously as representing your receipt of a certain amount of Bitcoin. Once the code has been accepted by the computers on the blockchain, your wallet’s information will say it has some Bitcoin in it, and then the code is sealed permanently into the next block on the chain.
