Sending Bitcoin might seem complex at first, but it’s a straightforward process once you understand the basics. Whether you're transferring to a friend, making a purchase, or moving funds between wallets, this guide walks you through everything you need to know.
What Is a Bitcoin Address?
A Bitcoin address is a unique digital identifier, much like an email address or bank account number. It’s used to send and receive Bitcoin on the blockchain. These addresses are generated from a public key and usually consist of a long string of letters and numbers, such as:
5M12w5XaTP37KMnZspyhrynaWpyiAeMALbYou can share your Bitcoin address publicly—it’s safe to do so. However, your private key must always be kept secure, as it grants access to your funds.
There are two main types of Bitcoin wallets:
- Custodial wallets: Managed by a third party (like an exchange). They often simplify the user experience and may allow off-chain transactions with lower fees.
- Non-custodial wallets: You control the private keys. These offer greater privacy and autonomy, but all transactions occur on-chain, often with higher fees.
How to Send Bitcoin from a Custodial Wallet
Using a custodial wallet (often provided by cryptocurrency platforms) is user-friendly and ideal for beginners. Here’s a general step-by-step process:
- Log in to your account and navigate to the “Wallet” or “Withdraw” section.
- Select Bitcoin (BTC) as the currency you want to send.
- Enter the recipient’s Bitcoin address. You can paste it manually or scan their QR code.
- Specify the amount you wish to send.
- Whitelist the address (if required). This is a security step to ensure funds are only sent to approved addresses.
- Review transaction details, including the network fee and total amount.
- Confirm the transaction.
Transactions between users on the same platform are often free, while external transfers incur a fee. Always double-check addresses before sending—Bitcoin transactions are irreversible.

How to Send Bitcoin from a Non-Custodial Wallet
Non-custodial wallets, such as software or hardware wallets, give you full control. Here’s how to send Bitcoin using one:
- Open your wallet app and select the “Send” option.
- Choose Bitcoin from your list of assets.
- Enter the destination address manually or via QR scan.
- Input the amount in BTC or your local currency (many wallets auto-convert).
Select transaction speed. Options usually include:
- Slow (lower fee)
- Medium (standard fee)
- Fast (higher fee for priority processing)
- Verify all details and approve the transaction.
Note: The recipient receives the amount minus the network fee. Miners collect this fee to process and confirm your transaction on the blockchain.
How to Send Bitcoin to Friends and Family
If you and the recipient use the same platform, transferring Bitcoin can be fast and low-cost. Steps often include:
- Go to the “Transfer” or “Send to Friends” section.
- Select a contact from your list or enter their username.
- Choose Bitcoin as the currency.
- Enter the amount and add a note (if desired).
- Confirm and send.
These transactions may be free or carry minimal fees since they are often processed off-chain.
How to Send Bitcoin to Someone Without a Wallet
Sending Bitcoin to someone who doesn’t have a wallet requires a bit more effort. Here are a few options:
- Recommend a user-friendly wallet: Encourage them to set up a custodial or non-custodial wallet. Many platforms offer free, quick sign-up processes.
- Use a crypto gift card: Some services allow you to purchase gift cards denominated in Bitcoin. The recipient can redeem them once they set up a wallet.
- Create a wallet for them: You can help them set up a wallet, but emphasize the importance of security and ownership. They should generate new keys and backup phrases themselves.
Remember: Never share private keys or recovery phrases.
Understanding Bitcoin Transaction Fees
Bitcoin transaction fees vary based on:
- Network congestion: More activity means higher fees.
- Transaction size: Larger data transactions (in bytes) cost more.
- Speed priority: Faster confirmations require higher fees.
Fees are calculated in satoshis per byte—a satoshi is the smallest unit of Bitcoin (0.00000001 BTC). During busy periods, fees can rise significantly.

Frequently Asked Questions
How long does a Bitcoin transaction take?
Bitcoin transactions usually take between 10 minutes to over an hour, depending on network congestion and the fee you pay. Higher fees often result in faster confirmations.
Can I cancel a Bitcoin transaction?
Once a Bitcoin transaction is broadcast to the network, it cannot be canceled. This is why it’s essential to verify all details before confirming.
What happens if I send Bitcoin to the wrong address?
If you send Bitcoin to an incorrect or invalid address, the funds may be lost permanently. Always confirm the recipient address carefully.
Are Bitcoin transactions anonymous?
Bitcoin transactions are pseudonymous—they are recorded on a public ledger, but identities are not directly tied to addresses. For greater privacy, use additional tools or methods.
What’s the difference between on-chain and off-chain transactions?
On-chain transactions are recorded on the Bitcoin blockchain and incur fees. Off-chain transactions (like internal platform transfers) occur outside the blockchain and are often instant and free.
Do I need a Bitcoin wallet to receive Bitcoin?
Yes, you need a Bitcoin wallet to receive, store, and send Bitcoin. Wallets manage your keys and addresses.

Sending Bitcoin is a simple yet powerful way to transfer value globally. Whether you use a custodial service for convenience or a non-custodial wallet for control, understanding the process helps you transact confidently and securely.
Always:
- Double-check addresses before sending.
