International payments have been a pain point for as long as money has crossed borders. Traditional rails—banks, SWIFT, remittance providers, card networks—can be slow, expensive, and full of hidden friction: intermediary fees, poor exchange rates, business-hour delays, capital controls, and paperwork. Bitcoin offers a radically different path. It lets you send value directly to anyone worldwide, 24/7, without needing a correspondent bank in the middle. In many use cases, especially cross-border transfers and remittances, Bitcoin (and increasingly the Lightning Network on top of Bitcoin) can cut costs and settlement times dramatically.
But “use Bitcoin internationally” isn’t just “buy some BTC and click send.” To do it safely and efficiently, you need to understand the payment options (on-chain vs Lightning), fees, conversion steps, and compliance realities. This guide walks you through everything—practically, honestly, and in detail.
1. When Bitcoin Makes Sense for International Payments
Bitcoin can be used for many kinds of cross-border payments, but it shines most in these scenarios:
Person-to-person remittances
Someone working abroad wants to send money to family at home quickly and cheaply. Crypto remittances are still a minority of global flows (estimated ~3–5% in 2025), but adoption is rising because of cost and speed advantages.

Freelancer and cross-border business payments
Paying contractors or suppliers abroad without waiting days for wires. Some businesses now treat Bitcoin or Lightning as an alternative settlement layer.

Payments into countries with limited banking access
In underbanked regions, Bitcoin is used because it requires only a phone and internet, not a bank account.

Transfers where traditional rails are restricted
Research suggests cross-border crypto flows can correlate with incentives to bypass capital restrictions.

If your international payment needs include very stable amounts (like tuition or invoices where the recipient must receive an exact local-currency value on a specific date), Bitcoin can still work—but you’ll want smart conversion strategies to manage volatility (see Section 6).
2. Two Ways to Send Bitcoin Internationally
2.1 On-chain Bitcoin transfers (Layer 1)
This is the “base layer” blockchain transaction. It is:
Globally verifiable and highly secure
Final after confirmations
Best for larger transfers
Fees vary with network congestion
On-chain transfers are often used for bigger remittances or business settlements where security matters more than instant speed.

2.2 Lightning Network transfers (Layer 2)
Lightning is a payment network built on Bitcoin. It allows:
Instant payments
Extremely low fees (often fractions of a cent)
Great for small to medium transfers or frequent payments
Enterprise and remittance studies show Lightning can reduce cross-border payment fees by ~50–80% in some implementations compared to legacy rails.

In practice, many international payments today are:
BTC on-chain → Lightning send → recipient converts locally.
This hybrid approach can be both cheap and fast.

3. What You Need Before Sending Bitcoin Abroad
Whether you use on-chain or Lightning, you need four basics:
A Bitcoin wallet
Self-custody wallets (you control keys) for maximal freedom.
Exchange wallets (custodied) for convenience and easier fiat conversion.
Either works, but self-custody requires more care.
Bitcoin to send
You can buy BTC via an exchange, broker, or a peer-to-peer marketplace depending on your country.
Learn Beem

The recipient’s receiving method
On-chain address (starts with 1, 3, or bc1…)
Lightning invoice or Lightning address
Make sure you know which network the recipient can accept.

A plan for local currency conversion (if needed)
Most recipients ultimately want fiat. You need to know how they’ll convert BTC to local currency—exchange, broker, P2P, or crypto-friendly remittance service.

4. Step-by-Step: How to Send Bitcoin Internationally (On-Chain)
Here’s a clean, real-world flow.
Step 1: Acquire Bitcoin
Create an account at a reputable exchange or use a trusted P2P service.
Complete identity checks if required (many countries require KYC).

Buy BTC using bank transfer, card, or local methods.
Step 2: Move BTC to the wallet you’ll send from
If buying on an exchange:
You can send directly from the exchange to the recipient, or
Withdraw to your own wallet first for more control.
With larger sums, many users prefer a self-custody wallet before sending.

Step 3: Get the recipient’s on-chain address
The recipient gives you a Bitcoin address.
Double-check every character. Bitcoin transactions are irreversible.

Step 4: Choose the network fee
Wallets usually offer:
low / medium / high fee
estimated confirmation time
Higher fee = faster confirmation.
For urgent transfers, choose medium/high. For non-urgent, low fees are fine.

Step 5: Send and wait for confirmations
Broadcast the transaction.
Recipient can see it almost immediately as “pending.”
After 1–6 confirmations (often ~10–60 minutes), it’s effectively settled depending on risk tolerance.

Step 6: Recipient converts BTC to local currency (optional)
Recipient options:
Sell on a local exchange
Use P2P markets
Use a Bitcoin-enabled remittance app
Spend BTC directly if merchants accept it
Many remittance guides now treat conversion as part of the end-to-end user experience.

5. Step-by-Step: How to Send Bitcoin Internationally (Lightning)
Lightning feels similar to sending a message.
Step 1: Get a Lightning-enabled wallet
Popular wallets include mobile Lightning wallets that handle routing automatically.
Step 2: Fund your Lightning wallet
You generally:
transfer BTC on-chain into the wallet, which opens/uses channels, or
buy BTC directly inside the Lightning wallet (depends on region).

Step 3: Get the recipient’s Lightning invoice
Recipient sends:
a QR code invoice
or a Lightning address (like an email-style handle).
Invoices specify amount and expiry time.
Step 4: Pay the invoice
Scan or paste invoice.
Confirm amount.
Payment settles instantly, usually with tiny fees.

Step 5: Recipient uses BTC/Lightning as desired
They can:
keep BTC
convert to fiat
spend through Lightning-connected services.
Growing real-world Lightning remittance activity in Africa and Latin America shows Bitcoin often acts as the backend liquidity layer for cheap cross-border flows.

6. Managing Bitcoin Volatility in International Payments
Volatility is the biggest practical concern. Your solution depends on your goal.
If you want the recipient to get a stable fiat value:
Send quickly after buying
Don’t hold BTC for days before sending.
Use Lightning for instant settlement
Less time exposed to price swings.
lightspark.com
+1
Convert immediately on receipt
Recipient sells to fiat as soon as funds arrive.
Split a large payment into tranches
Reduces single-moment price risk.
If you’re OK with BTC exposure:
Many senders/recipients actually want BTC exposure as savings, especially in inflationary economies. In those cases, volatility is a feature, not a bug.

7. Fees and Cost Comparison
Costs come from two places:
Network fees
On-chain fees rise when block space is crowded.
Lightning fees are usually tiny.
lightspark.com
+1
Exchange spread and conversion costs
When buying BTC or selling to fiat, you pay:
trading fee
bid/ask spread
sometimes withdrawal fee
Even with conversion costs, crypto remittances are often cheaper than traditional rails in high-fee corridors, where legacy remittance costs remain stubbornly high.

A simple mental model:
Traditional remittance: fee + FX markup + delay
Bitcoin remittance: exchange spread + (on-chain or LN fee)
For many corridors, especially when Lightning is used, the Bitcoin path can be meaningfully cheaper.

8. Security Best Practices (Don’t Skip This)
International payment errors are expensive. Keep it boring and careful:
Verify the recipient address/invoice twice
Send a tiny test transfer first if the amount is large.
Use reputable wallets and exchanges
Avoid unknown apps promising “zero fees, double your BTC” etc.
Enable two-factor authentication on exchanges
Exchanges are the usual weak spot in cross-border flows.

Watch out for scams in P2P conversions
If the recipient sells BTC P2P, they should use escrow-protected marketplaces.
Keep backups of your wallet seed phrase
If you lose your seed, your BTC is gone forever.
9. Legal and Compliance Realities
Bitcoin is permissionless at the protocol level, but most people interact with it through regulated services (exchanges, brokers, payment apps). That means compliance matters.
9.1 AML/KYC is standard at gateways
Most exchanges require identity verification and may ask for proof of funds when transfers are large.

9.2 The Travel Rule
A global AML standard from the Financial Action Task Force (FATF) requires VASPs (crypto service providers) to share sender/receiver info above certain thresholds (often ~$1,000). The EU’s rule applies from December 30, 2024 under Regulation (EU) 2023/1113, and similar rules exist elsewhere.

If you send from one regulated exchange to another, expect extra data fields or delays.
9.3 Local restrictions vary
Some countries tightly regulate crypto conversions; others are open. Your best safe rule:
Sending BTC P2P is usually lawful,
cashing out to banks may face stricter rules.
Always check local law if you’re moving significant value.
10. Practical Example Flows
Example A: Worker in Europe sending funds to Egypt (family remittance)
Buy BTC on a regulated exchange.
Transfer to a Lightning wallet.
Send a Lightning payment to family’s wallet.
Family converts to EGP through a local exchange or P2P service (or spends via BTC-friendly shops).
Lightning keeps fees low and settlement instant.

Example B: Business paying an overseas contractor
Business buys BTC or uses treasury BTC.
Sends on-chain for a large invoice, or Lightning for smaller frequent invoices.
Contractor holds BTC or sells locally.
Cross-border crypto flow research shows businesses increasingly use crypto rails where legacy banking is costly or unreliable.

The process is straightforward:
Get a reliable wallet.
Buy BTC.
Choose on-chain for bigger, slower settlements or Lightning for fast, cheap ones.
Send to the recipient’s correct address/invoice.
Convert locally if needed.
Follow good security and understand your jurisdiction’s rules.
Bitcoin doesn’t eliminate every friction—volatility and compliance still matter—but it gives you something traditional finance rarely offers: a global payment network that works the same way for everyone, everywhere, all the time. If you use it with care, it can be one of the most efficient ways to move value across borders in 2025 and beyond.
