Bitcoin (BTC), created in 2008 by Satoshi Nakamoto, revolutionized finance by enabling peer-to-peer, cross-border payments at a fraction of traditional costs. As the first and most popular cryptocurrency, it’s often the entry point for crypto enthusiasts. Once you’ve secured your BTC in a wallet, you might wonder how to transfer it. This guide covers everything from wallet addresses to transaction fees, ensuring you can send Bitcoin confidently.
Understanding Bitcoin Wallet Addresses
A Bitcoin wallet address is a 26–35-character string starting with '1', '3', or 'bc1'. It’s a user-friendly version of your public key, which identifies your account uniquely. Here’s what you need to know:
- Dynamic Addresses: Your wallet generates a new address for each transaction to enhance privacy and security.
- Key Pairs: Each address is linked to a public key (for identification) and a private key (for signing transactions).

How Bitcoin Transactions Work
1. Initiating the Transaction
- Specify the recipient’s address and amount.
- Confirm the details before signing.
2. Signing the Transaction
- Your wallet uses the private key to digitally sign the transaction.
- Signed transactions are broadcast to Bitcoin nodes for verification.
3. UTXO Model
- Bitcoin uses Unspent Transaction Outputs (UTXOs) like digital change.
- Example: Sending $1 from a $20 UTXO returns $19 as a new UTXO.
Steps to Send Bitcoin
1. Enter the Recipient’s Address
- Double-check the address—transactions are irreversible!
2. Specify the Amount
- Ensure you have enough BTC to cover the amount + network fee.
3. Confirm and Send
- Review details, sign, and broadcast the transaction.
Bitcoin Network Fees
Why Fees Exist
- Prevent spam and incentivize miners.
- Average cost: ~$2, but surges during high demand (e.g., $60 in 2021).
Calculating Fees
- Formula:
Fee = Transaction Size × Fee Rate(satoshis/byte). - Use a fee calculator for real-time estimates.
Transaction Speed
- Average time: 60 minutes (6 confirmations).
- Factors: Network congestion and fee amount. Higher fees = faster processing.
Security Tips
- Use a hardware wallet (e.g., Ledger) for offline private key storage.
- Avoid sharing private keys or using online wallets for large sums.
