Bitcoin learning guide
Published by Crypto Dispensers · 8 min read
Bitcoin addresses are generated by wallets and are used to route Bitcoin transactions across the network. You can share an address to receive Bitcoin, but you should never share your private key or recovery phrase.
To understand the full wallet picture, read our Bitcoin wallet guide. To learn how Bitcoin moves after an address is entered, see how Bitcoin transactions work.
Not a private key
Bitcoin wallet guide Transactions explained
Used to receive Bitcoin
Creates a receiving address
Uses the address as destination
Routes Bitcoin to that wallet
These three things work together, but they are not the same. A Bitcoin address is where Bitcoin is sent. A wallet manages addresses and transactions. A private key or recovery phrase controls access and must stay secret.
A Bitcoin address is the public destination you share when you want to receive Bitcoin. It tells the network where the transaction should go.
Use it to receive Bitcoin
A Bitcoin wallet is the tool that creates addresses, signs transactions, and helps you manage access to your Bitcoin. It can be a mobile app, desktop wallet, or hardware wallet.
Addresses, keys, and transactions
A private key or recovery phrase is the secret control layer behind a wallet. Anyone with it can potentially control the Bitcoin connected to that wallet.
This protects your access
How they work together
Generates a Bitcoin address
Shares the address to receive Bitcoin
Routes the transaction to that destination
Shows the Bitcoin after the transaction is received
Once you understand the difference between an address, a wallet, and a private key, Bitcoin becomes much easier to use safely.
A Bitcoin address does not hold Bitcoin by itself. It acts like a destination label. Your wallet creates the address, the sender uses it, the Bitcoin network checks the transaction, and your wallet shows the result after the transaction is received.
Address route monitor Active
A wallet can generate Bitcoin addresses for receiving Bitcoin. The address is public, but the private key or recovery phrase behind the wallet must remain secret.
You can copy the address, scan a QR code, or paste it into a payment flow. The sender uses that address as the destination for the Bitcoin transaction.
Once the sender approves the transaction, it is broadcast to the Bitcoin network. The network checks whether the transaction follows Bitcoin’s rules.
After the transaction reaches the address and receives confirmations, your wallet displays the Bitcoin connected to that transaction record.
Your Bitcoin is not stored inside the address like money inside an account. Bitcoin exists on the blockchain. Your wallet uses keys to prove control over the Bitcoin connected to your addresses.

Not every Bitcoin address starts the same way. Some begin with bc1, some begin with 1, and some begin with 3. These are different address formats, but they all help route Bitcoin to a wallet destination.
Many modern Bitcoin wallets use addresses that start with bc1. These are common for newer Bitcoin transactions and are often designed to support lower fees and better efficiency.
Some newer wallets create Taproot addresses that often start with bc1p. Taproot is part of Bitcoin’s ongoing technical improvement, but most beginners only need to know that it is another valid Bitcoin address style.
Older Bitcoin address formats may start with 1 or 3. You may still see them, but many newer wallets now prefer modern address formats.
You do not need to memorize every address format. You do need to make sure the address is copied correctly, belongs to the wallet you intend to use, and is meant for Bitcoin.
Bitcoin transactions are designed to be final. Before sending Bitcoin, slow down and confirm the address, wallet, amount, and network. A few seconds of checking can prevent a permanent mistake.
Address-check illustration Manual review
Do not send if the address looks different, the wallet changed unexpectedly, or someone is rushing you.
Use the address shown inside the receiving wallet. Avoid typing long Bitcoin addresses by hand. Copy and paste or scan a QR code when possible.
Compare every character of the pasted destination with the trusted receiving screen. Similar beginnings and endings can hide a substituted address. Stop if anything differs.
Only send Bitcoin to a Bitcoin address. Do not guess, force, or reuse instructions from another asset. If the network or wallet does not look right, stop.
Make sure the amount is correct before confirming the transaction. Once Bitcoin is sent and confirmed, it generally cannot be reversed.
QR codes can reduce typing mistakes. After scanning, verify the entire destination against the trusted receiving screen.
If someone is rushing you to send Bitcoin, pause. Urgency is one of the most common scam patterns.
A wrong address can create a permanent loss. Verify before sending, not after.
Check the full address after copying or scanning. For a hardware wallet, follow its instructions to verify the destination on the device display when supported. See Bitcoin.org’s malware guidance and how to find your receiving address. Shortened examples on this page are not payment destinations.
Can Bitcoin transactions be reversed? Bitcoin scams to avoid
On Bitcoin mainnet, native SegWit version 0 addresses begin with bc1q and use Bech32. Taproot addresses begin with bc1p and use Bech32m. Both can be valid Bitcoin destinations, but a sending service may support one and reject the other.
A prefix does not prove who controls an address, whether it is copied correctly, or whether your sending platform supports it. Verify the full address in your trusted wallet and check the sender’s current compatibility list. Never change the prefix yourself.

These are the questions beginners usually ask before receiving, sending, or checking a Bitcoin address.
No. A Bitcoin address is a public receiving destination. A wallet is the tool that creates addresses, manages keys, and helps you send or receive Bitcoin.
Yes, a Bitcoin address is designed to be shared when you want to receive Bitcoin. Do not share your private key, recovery phrase, wallet password, or account login information.
Not with only your public Bitcoin address. Your private key or recovery phrase controls access. That is why your address can be shared, but your private key must stay secret.
Bitcoin has different address formats. Some begin with bc1, some begin with 1, and some begin with 3. They can all be valid Bitcoin address styles, depending on the wallet and format used.
Bitcoin transactions are generally not reversible once confirmed. If Bitcoin is sent to the wrong address, it may not be recoverable. Always check the destination before sending.
It is safer to copy and paste the address or scan a QR code. Bitcoin addresses are long, and even one wrong character can create a serious problem.
Some wallets allow address reuse, but many wallets create new receiving addresses to improve privacy and organization. Follow the receiving address shown by your wallet.
Check that the receiving wallet says it is a Bitcoin address. Do not assume an address is correct because it looks similar to another crypto address. When unsure, stop and verify.
A Bitcoin address is public and used to receive Bitcoin. A private key is secret and controls access. Sharing an address is normal. Sharing a private key is dangerous.
In many purchase flows, you need a Bitcoin wallet address so the Bitcoin can be sent to the correct destination. A wallet can generate the address for you.
Now that you understand Bitcoin addresses, the next step is learning how Bitcoin moves across the network and how confirmations help show that a transaction has settled.
