Key Takeaways

• Understand Bitcoin wallet addresses and their importance.

• Follow a clear step-by-step process to send BTC securely.

• Be aware of network fees and how they affect your transactions.

• Always verify recipient addresses and amounts before sending.

• Use hardware wallets for enhanced security of your private keys.

Bitcoin (BTC) was created in 2008 by Satoshi Nakamoto—the first cryptocurrency in history. With its peer-to-peer, borderless, low-cost and efficient payment design, it has changed how traditional finance operates. For most people, buying BTC is just the starting point—the real skill is how to safely transfer Bitcoin to another wallet. This guide explains both the principles and hands-on steps you can follow directly.

Basics to Know Before Sending BTC

What is a Bitcoin wallet address?

Definition: The unique identifier for sending and receiving BTC, typically 26–35 characters, starting with 1, 3, or bc1.
Relation to keys: Each Bitcoin account is controlled by a key pair:
- Public key: Identifies your account.
- Private key: Signs transactions (must be kept secret).
  A wallet address is a human-readable representation of the public key, easier to record and share.
Why do addresses change? To protect privacy, most wallets generate a new receiving address each time. Old addresses remain valid, but using a fresh address for each receipt is recommended—especially with hot wallets—to reduce privacy and security risks.

How a Bitcoin Transfer Works On-Chain (What happens under the hood)

Start with a “wallet account”
You need a Bitcoin wallet to generate and store the private key (your control). Software wallets sign on your phone/computer—convenient but exposed to online risk. Hardware wallets sign on an offline device, then hand the signed transaction to your phone/computer to broadcast, preventing malware or network attacks from accessing the key.
Create the transaction (proposal/preview)
Enter the recipient address and amount. The wallet generates a transaction preview (some show more detail than others) for you to confirm or cancel.
Sign & broadcast
After you confirm, the wallet signs with your private key (a digital authorization for miners), then broadcasts to the network. Miners verify and include it in a block, writing it to the blockchain.
UTXO model (“spend the bill, get change”)
Bitcoin uses UTXO (Unspent Transaction Output):
- You actually spend entire UTXOs.
- The recipient gets the intended amount.
- You receive change back to your address as a new UTXO.
  Analogy: Pay with a $20 bill for a $1 bread; you hand over $20 and get $19 in change.

Complete a Bitcoin Transfer in 3 Steps

Get & enter the recipient address: Ask for the BTC address (1/3/bc1…), paste it into the wallet’s Send/Transfer screen, and check every character (on-chain is irreversible).
Enter the BTC amount: Make sure your balance covers amount + network fee.
Confirm & send: Verify all details (address, amount, fee priority), then sign and broadcast. Wait for miners to include it.

Tip: After sending, use a block explorer (e.g., mempool.space / blockchain.com) with the TXID to track progress and confirmations.

Step-by-Step: Send BTC with OneKey (Example)

The flow below applies to OneKey App + (optional) OneKey hardware wallet. Other wallets are similar.

Open OneKey App and switch to your Bitcoin (BTC) account.
Tap Send.
Paste the recipient’s BTC address (1/3/bc1…).
Enter the amount (e.g., 0.01 BTC).
Review the miner fee/network fee: choose Low/Medium/High or customize (advanced).
If using hardware, verify address and amount on the device screen, then confirm with the buttons.
After sending, copy the TXID and check confirmations in a block explorer.
Wait for the recipient’s acknowledgment or the agreed confirmation count (commonly 6).

Advanced: If the transaction is stuck, some wallets support “Speed Up” via RBF (Replace-By-Fee) or CPFP (Child-Pays-For-Parent) to boost priority.

Fees: Why you pay, how much, and how pricing works

Is sending BTC free?

No. Almost all on-chain actions require a network (miner) fee. Some centralized platforms offer free internal transfers, but those are off-chain and do not give you private-key ownership. Once you withdraw on-chain, you pay miner fees.

What is the Bitcoin network fee?

Definition: BTC you pay to have the transaction processed on the Bitcoin network.
Where it goes: To miners, who execute, include, and maintain the network. If you don’t include enough fee, the transaction may fail or remain unconfirmed for a long time.

How much does it cost?

Depends on two things:
1. Transaction size (bytes/vBytes),
2. Current network congestion (supply/demand).
Empirical ranges: Long-term averages around ~$2; during congestion (e.g., bull markets) peaks of $50–$60 have occurred; often fluctuates in the $10–$30 range.
Advice: Before sending, check a fee estimator or use your wallet’s real-time suggestion.

Why are fees needed?

Anti-spam: Discourages meaningless floods of transactions.
Incentives: Compensates miners’ energy and hardware costs—crucial for a sustainable decentralized network.

How are fees calculated?

Basic formula:
Fee = Transaction size × Fee rate (fee rate commonly sat/byte or sat/vB)

Higher rate → faster confirmation.
Too low → hours or days unconfirmed; in extreme cases you may need RBF or to resend.

How should I set BTC fees?

Not all wallets support custom fee rates, and beginners shouldn’t tweak them casually.
If yours does:
1. Find fee settings in the transaction details.
2. Choose Low/Medium/High presets or enter a custom sat/vB.
3. Review and send.
4. If unconfirmed and supported, use Speed Up / Increase Fee (RBF) in the pending list.

How long do transfers take?

The Bitcoin network adds a block roughly every 10 minutes.
A common practice is waiting for 6 confirmations for strong finality—about 1 hour.
Higher fees usually get picked faster; low fees can be significantly delayed.

Can I send BTC to someone without a wallet?

No. The recipient must provide a Bitcoin address to receive BTC.
Some services support fiat-covered or internal transfers, but those rely on custodians and are off-chain. The standard is: both parties use BTC wallets and control their own addresses/keys.

How do I receive Bitcoin?

Prepare a wallet that supports BTC (software or hardware).
Generate a BTC account/address (usually on the Receive page).
Copy the address and share it with the sender (check carefully).
Track confirmations in a block explorer or inside the wallet.
Your balance updates after confirmation.

Remember: Never share your private key or seed phrase—only your address.

A Safer Approach: Protect keys with a hardware wallet (OneKey example)

Offline signing: Private keys are used only inside the device—never exposed online.
Secure element + open-source stack: Better protection against physical attacks and less “black box” risk.
Companion app: Use OneKey App to create transactions, view fee suggestions, and review history—clear and intuitive.
Peace of mind: Verify address and amount on the device screen before confirming with buttons.

FAQ

Is it free to send BTC?
On-chain transfers aren’t free. Internal transfers are off-chain, and you don’t hold the private key.
Can I use Bitcoin for remittances?
Yes. BTC is decentralized, permissionless, and borderless—no intermediaries needed.
What if my transaction is stuck?
Likely too low a fee. Try RBF (fee bump) or CPFP, depending on wallet support.
Can I recover BTC sent to the wrong address?
Generally no. On-chain is irreversible. Always verify address and amount.

Conclusion

Sending BTC isn’t hard: understand addresses/keys, UTXOs, and fees, then follow
Get address → Enter amount → Set fee → Confirm & Send to complete safely.

Two golden rules:
