Imagine money that truly belongs to you...
No bank can freeze it. No government can inflate it. No intermediary can block it.

That's Bitcoin in its purest form!

In 2009, at the height of the global financial crisis, an anonymous creator named Satoshi Nakamoto posed a radical question. What if money could move directly between people without banks or governments as middlemen?

The answer was Bitcoin (BTC). The world’s first and most valuable cryptocurrency. Running on a peer-to-peer network, Bitcoin allows users themselves, not institutions, to verify and confirm transactions. By removing gatekeepers, it unlocked new possibilities -  moving money faster, cheaper, and giving individuals unprecedented control over their wealth.

Think of Bitcoin as digital gold you can email. When you send Bitcoin, you don’t wait for a bank, business hours, or approval. Instead, you tap into a borderless financial network that runs 24/7 - always on, always open, for everyone.

Why Bitcoin is revolutionary:
• Limited supply - only 21 million will ever exist, making it truly scarce
• Global accessibility - send value anywhere, anytime, with minimal fees
• Transparent security - every transaction lives on an unchangeable public ledger
• True control - no bank can freeze it, no hidden fees can be added

What Bitcoin can be:
• An investment and hedge against inflation
• A store of value, like digital gold
• A way to transfer money worldwide instantly
• A gateway into the broader world of emerging technologies

Far from a fringe experiment, Bitcoin is now legal to use, hold, and trade in most major economies. Today, you can spend it on everything from everyday purchases to travel, or even donate it to global charities. It embodies all the functions of money - medium of exchange, store of value, unit of account - while existing entirely in digital form.

At its heart, Bitcoin offers something traditional finance never could... financial sovereignty.
Your money. Your rules. Your freedom.

Long story short, Bitcoin itself is incredibly secure.

The blockchain doesn't sleep, it doesn't make mistakes, and once a transaction is confirmed, it’s permanent, transparent, and tamper-proof. That's why Bitcoin is a true digital fortress - no hacker, no bank, and no government can simply take it away from you.

But here's the catch. The safety of your Bitcoin isn't only about the blockchain - it's also about where you keep it. A fortress is only as strong as the walls around it.

With Change, your Bitcoin gets bank-level protection plus peace of mind:
• Cold storage - assets stored offline, out of hackers' reach
• EU banking regulations - same legal safeguards as your bank account
• ISO27001 compliance - the gold standard for security management
• Multi-signature wallets - institutional-grade protection protocols
• Insurance coverage - an extra shield beyond regulation
• Segregated accounts - your assets always held separately from company funds

Bitcoin is your unbreakable safe.
Change is the bank vault around it, guarded 24/7 by lasers, cameras, and security experts.
You get all the freedom of Bitcoin without the stress of wondering if it’s really safe.

Absolutely!

Bitcoin isn't just legal - it's one of the most regulated asset classes in modern finance. Unlike traditional banks tied to decades-old frameworks, Bitcoin now operates under cutting-edge regulatory structures built for digital assets. You're not entering the Wild West of finance, you’re stepping into a transparent, globally recognised system where you can legally buy, hold, sell, and spend your Bitcoin.

Major economies - including all of Europe, the US, Canada, Japan, and Australia - recognise Bitcoin as a legitimate asset. Corporations hold it, banks offer services around it, and governments tax it like any other investment. Today, you can legally use Bitcoin to:
• Buy through licensed platforms
• Store it securely in digital wallets
• Convert it back to local currency
• Make purchases where accepted
• Include it in your investment portfolio

At Change, you’re fully protected across all 30 EEA countries:
• Dutch AFM licence – official financial services provider
• Estonian FIU licence – authorised crypto service operator
• MiFID II compliance – Europe’s strictest investor protection standards
• Local compliance – aligned with every national cryptocurrency regulation

You're not venturing into a legal grey zone.
You're investing in a legitimate, regulated asset class backed by full European legal protection.
Jak ₿itcoin funguje?

Have you ever wondered how Bitcoin can exist without banks, governments, or any central authority pulling the strings? It sounds impossible but the answer lies in one of the most brilliant technological ideas of the last century.

Bitcoin cracked a problem economists once thought unsolvable. How to create digital money that can’t be copied, faked, or spent twice without needing a trusted middleman to approve every transaction? The solution wasn't a new bank, but a new system. A system that runs not on trust in people or institutions, but on trust in mathematics, cryptography, and a global network of computers working together.

Bitcoin is like digital cash with superpowers.
• Like cash, you can send it directly to anyone - no bank required.
• Unlike cash, every transaction is permanently recorded, verified worldwide, and impossible to counterfeit.

Here's what makes it tick!

THE BLOCKCHAIN
Picture a book of accounts that everyone can read, but nobody can erase or forge. That's the blockchain. Every Bitcoin transaction is written into this shared public record, organized into blocks that link together in order. Once something is in, it's there forever. This creates trust without institutions you don't need to believe a bank's database. You can check the blockchain yourself.

DIGITAL WALLETS
Your Bitcoin wallet doesn't actually hold Bitcoin - it holds keys:
• A public key, like an account number, that others use to send you Bitcoin.
• A private key, like your PIN, which proves you own it and lets you spend it.

When you send Bitcoin, you're really signing a message with your private key. The coins don't "move" - ownership just shifts on the blockchain.

MINING
Who keeps the ledger safe? Miners do. Around the world, powerful computers compete to solve puzzles, validate transactions, and add new blocks. The winner earns new Bitcoin and, more importantly, locks in the integrity of the network. This process, called Proof of Work, makes Bitcoin extremely secure. To cheat the system, you'd need more computing power than the rest of the planet combined. Mining also controls supply -  new Bitcoin is released at a predictable rate, capped at 21 million forever - digital scarcity, hard-coded.

Why Bitcoin matters?
Bitcoin solved the "double-spending problem" and became the first digital money that works without middlemen. The result? A financial system that’s:
• Faster than banks - no waiting for business hours.
• Cheaper than international transfers.
• More secure - no single point of failure.
• Borderless - just an internet connection, no bank account required.

SIMPLE TO USE
The technology is complex, but using Bitcoin is simple.
With a platform like Change, it takes just a few steps:
1. Convert euros into Bitcoin at the current rate.
2. See Bitcoin in your wallet instantly.
3. Send it to anyone, anywhere, with their address.
4. Wait minutes (not days) for confirmation.
5. Rest easy knowing it's recorded forever on the blockchain.

MORE THAN JUST MONEY
Bitcoins strength grows with its community - more users mean more security, more liquidity, and more legitimacy. And beyond money, its underlying blockchain has inspired new innovations in finance, supply chains, identity, and beyond. When you buy Bitcoin, you're not just holding a digital asset - you're plugging into a global financial network that never sleeps, never discriminates, and never shuts down.

THE FUTURE IS ALREADY HERE
Bitcoin isn't an experiment anymore - it's proof that decentralized systems can thrive at global scale. And with platforms like Change, you can start with as little as €10, backed by the security of European regulation.

The future of money isn't coming. It’s already here.
