Using Bitcoin in the Real World

Laszlo Hanyecz paid 10,000 BTC for two pizzas in May 2010. At today's price those coins would buy a small island. The Bitcoin community celebrates it as Pizza Day, and I think about it every time someone asks me whether Bitcoin is "actually usable" yet.

The honest read on that story: Bitcoin has travelled a long way as money, and it still has further to go. Where you can spend it depends on where you live, what you are buying, and whether you need the payment to clear in seconds or minutes. I work in the crypto self-custody space, and I get this question from Swiss friends almost weekly. So let me answer it the way I would over coffee.

Can I Spend Bitcoin?

Yes, though not everywhere and not always with grace.

The four practical paths today:

Online merchants. A merchant can offer Bitcoin at checkout. How it receives the money depends on its setup: BTCPay Server sends payments directly to the merchant's wallet, with fiat conversion available through plugins. Paying in BTC does not automatically mean the merchant receives francs or euros.

Gift card platforms. Bitrefill's Swiss catalogue lets you buy gift cards using Bitcoin or Lightning. You then redeem the card with the retailer. This is an indirect way to spend Bitcoin, subject to the card's terms and available balance.

Peer-to-peer transfers. Any wallet can receive Bitcoin from any other wallet, anywhere on the planet, with no bank or processor between them. It works whether or not the recipient's country has a functioning banking system, and whether or not the sender and recipient know each other.

In-person payments. Some physical shops accept Bitcoin. Lugano's Plan B merchant directory is one place to look for participating businesses. Confirm the payment method with the shop before ordering.

Bitcoin in Switzerland: More Than Crypto Valley

These Swiss examples illustrate different uses of Bitcoin: buying it, paying a public invoice, and shopping through a gift card. The service details below were checked on 16 September 2026.

SBB (Swiss Federal Railways). SBB advertises Bitcoin paper wallets for CHF 20–500 at its ticket machines, with a Swiss mobile-provider number required. Its product page lists cash, PostFinance Card and Maestro debit cards as payment methods. Buying Bitcoin there is different from paying for travel: SBB's published ticket-payment methods do not list direct Bitcoin payment.

Bitcoin ATMs. Värdex's ATM service offers Bitcoin purchases and sales for CHF cash, with cash-out waiting for blockchain confirmation. It advertises cash purchases below CHF 1,000 without KYC registration; a phone number is still required. Värdex's terms set a cash-transaction limit of CHF 1,000 per person over 30 days. Check the machine's availability, limits and quoted exchange rate before using it: Värdex includes its commission in that rate. An ATM is not a promise of unlimited or anonymous exchange.

Zug ("Crypto Valley"). The city began a Bitcoin-payment pilot in 2016 with a CHF 200 ceiling, as the canton's Finance Directorate recounts. Tax payments are a separate service: the cantonal tax administration has accepted Bitcoin and Ether since February 2021, with a current limit of CHF 1.5 million per transaction. This covers taxes invoiced by the canton, including municipal taxes it collects; it does not cover taxes invoiced separately by municipalities.

Lugano Plan B. Lugano launched Plan B with Tether in March 2022. For a concrete public-service use, the city accepts Bitcoin, Lightning and USDT for all city-issued invoices, including taxes, fees and fines, without an amount ceiling. The city lists a 1% conversion fee charged by its payment partner, included in the exchange rate. Merchant participation is separate from municipal invoice payment. Check a transport or utility provider's own payment options rather than assuming the city scheme covers it.

Bitrefill and gift cards. At the check, Bitrefill listed Swiss Coop cards in CHF 20–100 denominations and IKEA cards for CHF 10–300, payable with Bitcoin or Lightning. Check the country, redemption rules and expiry before buying. Purchase limits vary by account and product, and identity verification may be requested. A gift-card purchase does not mean the retailer accepts Bitcoin directly.

For everyday use, the useful question is whether your specific shop or bill supports the payment you want to make, at a total cost you accept.

The Lightning Network: Bitcoin for Everyday Payments

On-chain confirmation arrives with a mined block, and during congestion the fee can rival the price of your coffee. A busy checkout needs a faster way to confirm payment.

Lightning is a second layer that can complete payments in seconds. Routing fees are often small, but wallet service charges, swaps and channel funding can add to the total. Check the quote for your payment.

Two parties open a payment channel with an on-chain funding transaction. They can then update their balances repeatedly without paying a miner for each update. A cooperative close pays out the final balances in another on-chain transaction. Resizing a channel or resolving a forced closure can add transactions and costs.

You do not need a direct channel with everyone you pay. Lightning routes through interconnected channels when a path with enough liquidity is available. A payment can fail or remain pending, so wait for its final status before retrying. Lightning Labs explains routing and payment states.

The mempool.space Lightning API, checked on 13 September 2026, returned an observation dated 30 August 2026 at 00:00 UTC: 16,242 nodes, 32,678 channels and about 3,795 BTC in capacity. That is a public-graph snapshot at a point in time, excluding private channels. It measures capacity rather than transaction volume or total adoption.

Wallets hide much of this complexity, but their designs differ. Phoenix runs native Lightning channels; Misty Breez's Liquid implementation uses swaps; Wallet of Satoshi now offers Spark self-custody alongside region-dependent custodial service. Read Chapter 10 before choosing a wallet or assuming every version has the same custody and recovery model.

Lightning can suit a coffee, a tip or a small freelance invoice when the recipient supports it and the total fee makes sense.

Remittances: Sending Money Across Borders

Bitcoin can move value across borders without a bank wire, but compare the complete cost and delivery time for the route you need. An on-chain transaction's network fee depends on its size and chosen fee rate, not the recipient's country. Lightning routing also works across borders, while wallet and conversion charges can still apply.

The friction is often the last mile. If the recipient needs local currency, buying Bitcoin at one end and selling it at the other introduces exchange spreads, service fees and availability constraints. Check how much usable local money arrives. A provider's global Bitcoin payment reach does not mean it offers accounts or bank payouts in every destination country.

Fees and Confirmation Times in Practice

On-chain fee estimates change with demand for block space. At the 13 September 2026 check, mempool.space's recommended-fee API returned 1 sat/vB for its fastest, half-hour and hour targets. This was a retrieved estimate, not a guaranteed confirmation time or a typical fee for the year. A transaction of 140 virtual bytes at that rate would pay 140 sats in miner fees; your transaction size and provider charges may differ.

For a time-sensitive payment, inspect the wallet's current estimate and full fee before sending. A higher fee can improve its chance of inclusion, but blocks arrive at irregular intervals. Bitcoin.org explains confirmation times and fees.

For a non-urgent transfer, a lower fee may be suitable if I can tolerate a longer wait. For a small purchase, I compare the Lightning quote with the on-chain quote, including any setup or liquidity charges. There is no fixed CHF amount below which one route is always cheaper.

Regulation and Taxes: What Swiss and European Holders Need to Know

This is the area where rules matter, change often, and vary by country. The framework below reflects mid-2026. Talk to a qualified tax adviser for your situation.

Switzerland. Bitcoin counts as a moveable asset (Vermögenswert). Private capital gains from Bitcoin trading are tax-free for natural persons who do not qualify as professional traders. Bitcoin holdings face annual wealth tax and must appear on your tax return at year-end value. The Swiss Federal Tax Administration (ESTV/AFC) publishes official year-end exchange rates for Bitcoin and other digital assets for exactly this purpose.

European Union. The European Commission’s DAC8 guidance, checked September 13, 2026, sets 2026 as the first reporting year for reportable crypto-asset transactions of EU-resident users, including through relevant non-EU operators. The first exchanges between EU tax authorities are due by September 30, 2027. This does not establish a Swiss CARF exchange for 2026: Switzerland has a separate timetable and partner-activation process, explained in Chapter 19.

El Salvador. A useful international data point: El Salvador made Bitcoin legal tender in 2021. Following an IMF agreement in December 2024 and a parliamentary amendment in January 2025, Bitcoin's legal-tender status was rescinded with effect from 1 May 2025. Bitcoin acceptance there is now voluntary. The lesson I take from it: even "permanent" policy victories revert when bigger creditors lean on the country.

Practical step. Keep records of every Bitcoin purchase, sale, and meaningful transaction. Log the date, the CHF or EUR equivalent at that moment, and the nature of the transaction. That log is the foundation of any tax filing you ever do, in any country.

Risk Note

Merchants stop accepting Bitcoin at any time. Fees and confirmation times move with network conditions and spike during busy periods. Regulation and tax treatment shift between countries and within them. Every Bitcoin user should know the rules that apply to them.

Reader Takeaway

• You can spend Bitcoin online, peer-to-peer, via gift cards, and at participating physical shops.
• Use Lightning for small fast payments. On-chain suits larger or less time-sensitive transfers.
• Cross-border payment is one of Bitcoin's strongest real-world cases, though the last-mile cash-out remains a friction point.
• Swiss holdings face wealth tax. EU DAC8 reporting requirements are live, with the 2026 tax year as the first full reporting cycle.
• Log every transaction. Talk to a tax professional if you trade actively.

Chapter Summary

• You can use Bitcoin for online purchases, gift cards, peer-to-peer transfers, and at participating physical merchants. Check each service's availability and terms.
• Lightning can complete everyday payments in seconds. Compare routing, wallet and liquidity fees, and check that the payment succeeded.
• On-chain costs depend on transaction size and the current fee rate. Check mempool.space and the wallet quote before sending; a snapshot is not a guarantee of future fees or confirmation time.
• Switzerland treats Bitcoin as a wealth-tax-liable asset with tax-free private capital gains for non-professional traders. EU countries are now enforcing mandatory crypto tax reporting under DAC8. The 2026 tax year is the first full reporting cycle.
• Accurate transaction records are non-negotiable in any tax jurisdiction.
