Using Bitcoin in the Real World

When Bitcoin was introduced in 2009, the only way to "use" it was to mine it yourself or swap it with fellow enthusiasts on internet forums. The most famous early real-world transaction — 10,000 Bitcoin exchanged for two pizzas in May 2010 — is now commemorated annually as Pizza Day. Today those coins would be worth hundreds of millions of dollars.

That story captures two things about Bitcoin's real-world utility: it has come an enormous distance, and it still has a long way to go. Where you can spend it today depends heavily on where you live, what you are buying, and whether you need the payment to settle in seconds or minutes.

Can I Spend Bitcoin?

Yes — but not everywhere, and not always conveniently.

The clearest use cases in 2025 are:

Online merchants. A growing number of e-commerce businesses accept Bitcoin directly, particularly in technology, privacy-focused services, and international trade. Payment processors such as BitPay, OpenNode, and the self-hosted BTCPay Server allow any merchant to accept Bitcoin and, if they choose, automatically convert it to local currency. The merchant receives euros or francs; you pay in Bitcoin.

Gift card platforms. Services like Bitrefill and The Bitcoin Company (in the US context) allow you to buy gift cards for hundreds of major retailers using Bitcoin. In practice this means you can use Bitcoin to shop at stores that do not accept Bitcoin directly — from supermarkets to travel bookings to streaming services. For Swiss users, this is one of the most practical daily-use options.

Peer-to-peer transfers. Anyone with a Bitcoin wallet can receive Bitcoin from anyone else, anywhere in the world, without a bank or payment processor involved. This works regardless of whether the recipient's country has a functioning banking system or whether the sender and recipient have any formal financial relationship.

In-person payments. Some physical shops, particularly in cities with active crypto communities, accept Bitcoin directly. In Zug, Switzerland — often called Crypto Valley — a meaningful number of restaurants, hotels, and service providers have accepted Bitcoin for years. Coverage elsewhere in Switzerland and Europe is uneven.

The Lightning Network: Bitcoin for Everyday Payments

On-chain Bitcoin transactions — transactions recorded directly on the Bitcoin blockchain — have two characteristics that make them unsuitable for small, everyday payments: they take minutes to confirm, and fees during busy periods can rival the value of what you are buying.

The Lightning Network solves this. Lightning is a second layer built on top of Bitcoin that enables near-instant payments for tiny fees — typically well under a centime per transaction.

The mechanism: two parties open a payment channel between them by locking some Bitcoin in a shared on-chain transaction. Once the channel is open, they can transact back and forth instantly and nearly for free, without touching the blockchain. When they are done, they close the channel and the final balance settles on-chain in a single transaction.

More significantly, you do not need a direct channel with every person you want to pay. Lightning payments route through a network of interconnected channels. Pay someone across the world by routing through a few intermediary nodes — the payment settles in seconds.

In 2025, Lightning Network capacity stands at approximately 3,850 to 4,200 BTC across the network. Apps like Phoenix Wallet, Breez, and Strike handle the complexity automatically. For the end user, the experience is similar to any mobile payment: scan a code, confirm the amount, done.

Lightning is the practical tool for buying that coffee, tipping a content creator, paying a small freelance invoice, or using Bitcoin for any purchase where speed and low cost matter.

Remittances: Sending Money Across Borders

One of Bitcoin's clearest real-world applications is cross-border money transfer. A traditional bank wire from Switzerland to a family member in a developing country typically costs 5 to 10 percent of the amount sent and takes one to five business days. On top of that, the recipient may face additional fees converting foreign currency.

Bitcoin can reduce this significantly. Sending 0.01 BTC on-chain costs the same regardless of whether the recipient is in Zurich or Nairobi. On Lightning, the fee for a cross-border transfer is negligible.

The practical friction point is the "last mile" — the recipient must have a way to convert Bitcoin to local currency. In countries with active Bitcoin adoption, peer-to-peer markets and local exchanges fill this role. In countries without this infrastructure, the usefulness is more limited.

Fees and Confirmation Times in Practice

For on-chain transactions in 2025, average fees under normal network conditions run roughly USD 1.50 to USD 2.00 per transaction. This is the equivalent of a few CHF. Most wallet software suggests appropriate fees automatically and lets you choose between faster (higher fee) and slower (lower fee) confirmation.

Practical guidance:

For purchases or time-sensitive payments, use the standard or fast fee — roughly CHF 1.50 to CHF 4 depending on conditions.

For non-urgent transfers to your own wallet or a known recipient, a lower fee is fine. The transaction will confirm within a few hours at most during normal conditions.

For very small amounts — under CHF 5 — on-chain fees make direct Bitcoin transactions impractical. Use Lightning instead.

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

This is an area where the rules matter, change regularly, and vary by country. The following reflects the situation as of 2025. Consult a qualified tax adviser for guidance specific to your situation.

Switzerland. Bitcoin is treated as a moveable asset (Vermögenswert). Private capital gains from Bitcoin trading are generally tax-free for natural persons not operating as professional traders. However, Bitcoin holdings are subject to annual wealth tax and must be declared on your tax return at the year-end value. The Swiss Federal Tax Administration (ESTV/AFC) publishes official year-end exchange rates for Bitcoin and other digital assets each year for this purpose.

European Union. The EU's Crypto-Asset Reporting Framework (CARF), aligned with the OECD's international framework updated in July 2025, requires crypto exchanges and service providers to report user transaction data to tax authorities. The EU's DAC8 directive mandates this reporting and member states must implement it by 31 December 2025, with the first reporting year being 2026. This means your transactions on European exchanges will be automatically shared with your national tax authority starting from the 2026 reporting cycle.

El Salvador. A notable international data point: after striking a deal with the IMF in 2025, El Salvador made Bitcoin acceptance voluntary rather than mandatory. The country remains a legal-tender jurisdiction for Bitcoin, but businesses are no longer required to accept it.

Practical step: Keep records of every Bitcoin purchase, sale, and significant transaction. Record the date, the CHF or EUR equivalent at the time, and the nature of the transaction. This is the foundation of any tax reporting you may need to do, regardless of which country you live in.

Risk Note

Merchants can stop accepting Bitcoin at any time. Fees and confirmation times vary with network conditions and can spike during busy periods. Regulation and tax treatment differ significantly between countries and are actively evolving. Every Bitcoin user should understand the rules that apply to them.

Reader Takeaway

• Bitcoin can be spent online, peer-to-peer, via gift cards, and at an increasing number of physical locations.
• Use Lightning Network for small, fast payments. On-chain is better suited for larger or less time-sensitive transfers.
• Cross-border payments are one of Bitcoin's strongest real-world use cases, though the last-mile cash-out remains a friction point.
• In Switzerland, Bitcoin holdings are subject to wealth tax. In the EU, reporting requirements are tightening under DAC8 from 2026.
• Keep records of all your transactions. Consult a tax professional if you are actively trading.

Chapter Summary

• Bitcoin can be used for online purchases, gift cards, peer-to-peer transfers, and at some physical merchants — particularly in crypto-friendly locations like Zug.
• Lightning Network enables near-instant, near-free payments for small amounts and is the practical choice for everyday Bitcoin spending.
• Average on-chain fees in 2025 run roughly USD 1.50 to USD 2.00 under normal conditions. Fees spike during high-demand periods.
• Switzerland treats Bitcoin as a wealth-tax-liable asset with tax-free private capital gains (for non-professional traders). EU countries are implementing mandatory crypto tax reporting from 2026 under DAC8.
• Keeping accurate records of all transactions is essential for any tax jurisdiction.
