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.
A Bitcoin address indicates the source or destination of a Bitcoin payment. 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. To combat this security issue, consider only letting fingerprint authentication open your mobile wallet app.
Bitcoin address format
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. Due to how Bitcoin has developed, improving over time, you will find that addresses are backwards-compatible.
What Is a Bitcoin Address? A 3-Minute Rundown
It is also possible to send from a legacy address to a Bech32, but there may be issues due to older wallet clients that use legacy addresses often not recognizing Bech32 or P2SH addresses as valid, therefore not letting you send, even though the transaction would likely go through. When in doubt, a legacy address provides the most peace of mind and is most widely supported.
While you may be limited by the client you are using, if it lets you sign and send the transaction, you have nothing to worry about. Bitcoin addresses are cross-compatible and each type should be able to send to one-another. For greater flexibility and less confusion, simply upgrade to Trezor Suite , where you have full control over the address types you use.
Of the address types described here, both P2SH and Bech32 are associated with the segregated witness upgrade, a newer transaction protocol upgrade that lets more data be sent per block, increasing network throughput. That means that the benefits SegWit provides are only effective when sending from a SegWit-compatible address like P2SH or Bech32, and the receiving address does not matter.
From a privacy standpoint, though, it is important to make sure that any cryptocurrency left over from a transaction is returned to an address of the same type. This is automatically managed by Trezor Suite. Newcomers may be confused about how to actually create an address to send funds to.
All you need is a wallet client, such as one of the recommended wallets listed here , which can generate a seed for you and use that seed to show you the available addresses. It is good practice to only use an address once, whether for sending or receiving. If you have a Trezor hardware wallet, you can use the Trezor Suite desktop application to create and manage your bitcoin addresses, which uses the seed created on your Trezor device itself, meaning there is no chance someone else has seen your seed and can duplicate your wallet.
You can also easily generate and verify a new address for every transaction directly in Suite.

If you want to send bitcoin to your wallet, you need to identify your receiving address. In Trezor Suite, this is done by choosing the account you want to receive to and clicking on the Receive tab. There, you will find a list of all addresses you have previously generated, and a preview of the latest unused address will be shown.
Check and confirm that each character of the address shown on your device matches what is shown on your screen, and then copy it and provide it to whomever is sending the transaction. As you can see, here we are using a Bech32 address starting in bc1, but unless the sender is also using a Bech32 or P2SH address, they will not be able to take advantage of the lower fees SegWit enables. Always send from a Bech32 address where possible to save on transaction fees. If it is your first time receiving a transaction, it is recommended to send a test transaction before moving all of your funds.
This may seem overly cautious as the technology is reliable but, for beginners, it can help offset any uncertainties. Try sending a few satoshis to test your receiving address, and wait for it to confirm before you make a larger transaction. When you want to pay someone in bitcoin, all you need is a receiving address which they will provide. Using Trezor Suite, simply navigate to the Send tab in your accounts, and enter the address you were supplied. Double check that the characters match the original address exactly, as there is always a chance that undetected malware could be hijacking your clipboard.
Once an address is entered, simply say how much you wish to send and a fee you are willing to pay. A higher fee will encourage miners to give your transaction higher priority and it should complete faster. In the screenshot below, we use the highest fee suggested by Trezor Suite to achieve a confirmation time of 10 minutes, the fastest the Bitcoin network is generally capable of. Always check the fee you are paying is reasonable. Some wallets which automatically suggest fees grossly overestimate it. You should never need to pay more than a few dollars in fees even during busy periods.
If the fee suggested by the wallet client you are using seems too high, look for an option to enter a custom fee and set it based on your needs. A number of tools exist on the internet to let you view the current fees other users are paying, such as the second chart on this website. In most cases, there is no way to recover Bitcoin that has been sent to the wrong recipient if the address was valid.
In the rare case that you know the owner of the address who you sent to, you can contact them, or you may be lucky enough that they send back the transaction when they recognize it was sent accidentally. This is highly unlikely to work so, to prevent yourself from losing your coins permanently by sending them to the wrong address, always double or triple-check the address before sending.

The sad reality is that, while many wallet clients do a good job of identifying valid addresses, there are still cases where a user has sent to the wrong type of address, such as sending Bitcoin to a Litecoin address, which some wallet clients are not able to catch. The chances of recovering your coins in this situation depend on the type of network the transaction was sent to. In some cases, like with Litecoin, you should be able to recover the coins as long as you also own the private key to the receiving address, even if it is a Litecoin address. Without a private key, however, chances of recovery are low, if not zero.
If this has happened, you may have to cut your losses and move to using a wallet interface with better support.
