📤 Send & Receive Basics
Time Required: 10 minutes
📬 Receiving Bitcoin (The Easy Part)
Receiving bitcoin is simple and safe. You can't lose funds by receiving - only by sending to the wrong address.
How to Receive Bitcoin:
- Open your wallet app
- Tap "Receive" or the receive icon
- You'll see a QR code and a long address
- Share the address OR the QR code with the sender
- Wait for confirmation (usually 10-30 minutes)
Understanding Bitcoin Addresses
- Each wallet can generate unlimited addresses
- All addresses connect to the same wallet balance
- It's SAFE to reuse addresses, but better to generate new ones
- New address each time = better privacy
Example Bitcoin Address:
This is what a modern Bitcoin address looks like. Starts with "bc1" (most common) or sometimes "3".
📤 Sending Bitcoin (Requires Caution)
Sending bitcoin is irreversible. Once confirmed, it cannot be undone. There's no "undo" button, no customer service, no refunds.
Before You Send: Critical Checks
- VERIFY the address - check first 4 and last 4 characters
- Send a SMALL test transaction first ($5-10)
- NEVER type addresses manually - always copy/paste or scan QR
- Double-check you're on the correct network (Bitcoin, not Lightning)
How to Send Bitcoin:
- Open your wallet app
- Tap "Send" or the send icon
- Paste the recipient's address or scan their QR code
- Enter the amount to send
- Select transaction fee (more on this below)
- Review EVERYTHING carefully
- Confirm and wait for blockchain confirmation
🔍 Try It: Look Up a Real Bitcoin Transaction
See how transactions appear on the blockchain. This is the first-ever Bitcoin transaction to another person (Satoshi → Hal Finney, January 2009):
What you should notice...
- 10 BTC sent (worth millions today!)
- Transaction has inputs (where bitcoin came from) and outputs (where it went)
- Tiny fee (0.00000000 BTC) - fees were negligible in 2009
- Thousands of confirmations over 15+ years
- Every transaction is permanently visible on the blockchain
Understanding Transaction Fees
Bitcoin transactions require a miner fee to process. You choose how much to pay. Higher fee = faster confirmation.
| Fee Level | Speed | Cost | When to Use |
|---|---|---|---|
| Low | 1-24 hours | $0.50-2 | No rush, saving money |
| Medium | 10-60 min | $2-5 | Normal transactions |
| High | 10-30 min | $5-20 | Urgent payments |
Fee Strategy
- Most wallets suggest a fee automatically - usually safe to accept
- Fees fluctuate based on network demand
- Weekend/off-hours = lower fees
- For large amounts, a higher fee is worth the speed
- Check mempool.space to see current fee rates
⚡ Check Current Network Fees
See real-time fee estimates and mempool status:
View Live Mempool → Try Fee Calculator Tool →Tracking Your Transaction
After sending, your transaction enters the "mempool" (waiting area) until miners include it in a block.
Transaction Status:
- Unconfirmed: Waiting in mempool (0 confirmations)
- 1 Confirmation: Included in a block (~10 min)
- 3+ Confirmations: Considered secure (~30 min)
- 6+ Confirmations: Fully settled (~60 min)
How to Track:
- Your wallet will show transaction status
- Copy transaction ID (txid) and paste into mempool.space
- You'll see real-time confirmation count
- Most merchants accept after 1 confirmation
