If you want to buy or sell items with Bitcoin, you need to be able to send and receive your funds from a certain location, kind of like sending and receiving mail through a mailbox.

But since we’re talking about sending and receiving Bitcoins -- and not postcards -- the location where you send and receive Bitcoins is actually on the internet and represented by a long series of letters and numbers.

It’s called a Bitcoin address.

Most blockchain experts recommend generating a new Bitcoin address each time you send or receive a payment, though. This personal security measure makes it harder for people to trace where your Bitcoin funds come from and where they go.

To get a Bitcoin address, you first need to download a Bitcoin wallet, which is software that allows you to securely send, receive, and store Bitcoin funds in the Bitcoin network.

Bitcoin wallets also store your private key, which is essentially your Bitcoin password. The software will generate a brand new Bitcoin address for you every time you create an invoice or receive a payment request for Bitcoins too.

There are four types of Bitcoin wallets that you can use: mobile, web, desktop, and hardware.

Mobile wallets are the most convenient wallets to access, but your wallet provider will store your key on its app or your phone, so if someone knows your phone’s passcode and accesses it, they can easily send all your funds to one of their Bitcoin addresses.

To combat this security issue, consider only letting fingerprint authentication open your mobile wallet app.

You can download mobile wallets in the app store on IOS, Android, and Windows Phone.

Here's a list of some:

Web wallets are equally as convenient as mobile wallets, but they’re also just as risky.

If someone knows a few of your personal details, like your phone number, email address, and birthday, they can impersonate you, telling your wireless service provider that you need to switch your number to a new phone -- their phone.

Then, they can go to your email account, click "forgot my password", and your email service provider will text a "change my password" code straight to their phone. This allows them to break into your email account, prompt your Bitcoin wallet provider to send a "change my password" email, and hack into your Bitcoin wallet account, stealing all your funds.

Consider telling your cell phone carrier to ask for a passcode before any of your account details can change -- it'll be nearly impossible for hackers to uncover it.

You can sign up for a web wallet on a wallet provider’s website.

Here's a list of some:

Desktop wallets are software programs that you can install on your computer. They’re more secure than mobile and web wallets, but hackers can still exploit vulnerabilities in a desktop wallet’s security, like extracting unencrypted account recovery phrases, to steal your bitcoins.

Consider only using a wallet that encrypts your private key and account recovery phrases.

Here are some desktop wallets you can install on your computer:

Hardware wallets are like external hard drives for your Bitcoins. They’re physical, offline pieces of hardware that you can plug into your computer to buy and sell items with Bitcoin and store in a safe place when you’ve finished conducting business.

Hardware wallets are the most secure way of storing your bitcoins because they limit your funds’ exposure to the internet and potential hackers.

Here are some hardware wallets you can buy online:

Bitcoin addresses are 26-35 characters long, consist of alphabetic and numeric characters, and either begin with “1”, “3”, or “bc1”.

Currently, there are three Bitcoin address formats in use:

1. P2PKH (address starts with the number “1”)

Example:

2. P2SH (address starts with the number “3”)
