Faced with the rise of Bitcoin and cryptocurrencies, central banks have decided to fight back. Their weapon? CBDCs (Central Bank Digital Currencies) — digital versions of their traditional currency.

The digital euro, the digital yuan, the digital dollar... These projects are presented as a "modernization" of the financial system. But behind the marketing terms lies a fundamental issue: the level of control that states will have over your money.

In this article, we compare CBDCs and Bitcoin in detail — two digital technologies with diametrically opposed philosophies.

What Is a CBDC?

The digital euro arrives in 2029: total programmable surveillance.

Definition

A CBDC (Central Bank Digital Currency) is a digital currency issued and controlled by a central bank. It is the digital equivalent of banknotes and coins, but in electronic form.

What a CBDC is NOT:

• A private stablecoin (like USDT or USDC)
• A decentralized cryptocurrency (like Bitcoin)
• Commercial bank money (your checking account)

What a CBDC IS:

• A direct claim on the central bank
• A monetary policy tool
• A state-controlled payment system

Projects Around the World

Over 130 countries (representing 98% of world GDP) are currently exploring CBDCs.

The Digital Euro: Where Do We Stand?

The ECB (European Central Bank) is actively working on the digital euro:

Updated timeline (December 2025):

UPDATE October 2025: The ECB signed framework agreements with 10 tech giants to provide operational and infrastructural components for the digital euro. Contract value: over €1.1 billion.

"The ECB's work is done. The design of the digital euro, including its privacy features, is now in the hands of European legislators."

— Christine Lagarde, ECB President

December 2024 — EU Council Support:

The EU Council approved a version of the digital euro including:

• Online AND offline functionality (usable without connection)
• Promise of "cash-like privacy" for small transactions

Announced features:

• Accessible to all European citizens
• Usable online and offline
• Holding limit (€3,000 initially envisaged)
• No remuneration (or potentially negative)
• Coexistence with cash (for now)

Europe and Debt Without Consent

Even before the digital euro arrives, the European monetary system already allows citizens to be committed without their direct consent.

Recent example: The €90 billion for Ukraine (2024)

The European Union raised €90 billion in common debt to fund aid to Ukraine. This mechanism, called "Ukraine Facility," commits all European citizens:

• Who voted? European leaders, not citizens
• Who will repay? European taxpayers via future taxes
• Amount per citizen: ~€200 per EU inhabitant
• Duration: Repayment over several decades

This is the second time the EU has issued massive common debt (after the €750 billion COVID recovery plan). A precedent that opens the door to further borrowing... always without a referendum.

The link with CBDCs: With a digital euro, governments could go even further:

• Automatic deductions from your holdings for "exceptional contributions"
• Solidarity taxes levied directly on balances
• Impossible to opt out (no cash alternative)

The current system already commits you to debts without asking your opinion. The digital euro would make this power absolute and instantaneous.

The Digital Yuan: The Chinese Model

China is the most advanced country in deploying its CBDC:

Statistics (end of 2024):

• 260 million users
• 180 billion yuan in transactions
• Used in 26 pilot cities
• Integrated into popular apps (Alipay, WeChat)

Known features:

• Total transaction traceability
• Programmable expiration (money can have an expiry date)
• Possible geographic restrictions
• Integration with the social credit system

The digital yuan is often presented as the model other countries might follow.

The Fundamental Differences

Fixed vs infinite supply, decentralized vs centralized: two opposing philosophies.

Structural Comparison

Opposing Philosophies

Bitcoin was created to:

• Escape central bank control
• Enable transactions without intermediaries
• Offer a fixed-supply store of value
• Resist censorship and surveillance

CBDCs are created to:

• Maintain central bank control
• Replace cash (traceable)
• Enable more "efficient" monetary policies
• Monitor and potentially control financial flows

These are two diametrically opposed answers to the same question: "What is the future of money?"

The Risks of CBDCs

Surveillance, programmable money, negative rates: total control over your spending.

1. Total Surveillance

Unlike cash (anonymous) or even bank transfers (traceable but with limits), a CBDC enables complete, real-time surveillance of all your transactions.

What the state could know:

• Every purchase you make
• Every person you send money to
• Your consumption habits
• Your opinions (donations to organizations)
• Your movements (localized payments)
• Your addictions (tobacco, alcohol, gambling)

Potential applications:

• Automated commercial profiling
• Chinese-style social score
• Detection of "suspicious" activities
• Personalized tax targeting

Financial privacy, already eroded, would completely disappear.

2. Spending Control: Programmable Money

A programmable CBDC would allow controlling what you can buy. This is not science fiction — tests are already underway.

Real Cases of Programmable Money

China - Suzhou (2023): In a pilot program, residents received digital yuan envelopes usable only within a defined geographic area. The money could only be spent in shops within the participating neighborhood. Leave the zone? The money is unusable.

China - Shenzhen (2020-2022): Distribution of digital yuan "lotteries" with expiry dates. Winners received 200 yuan (~€25) that had to be spent within 7 days, in participating shops only.

Australia - "Income Management" Pilot (existing): The "BasicsCard" for welfare recipients already limits purchases: impossible to buy alcohol, tobacco, or gambling. The CBDC would extend this control to everyone.

United Kingdom - Official Proposals: The Bank of England governor explicitly mentioned that CBDCs could be "programmed" for certain restrictions.

Individual Carbon Quotas

Several European countries are studying the idea of personal carbon quotas — and CBDCs would be the ideal tool to implement them:

• Every citizen would have an annual "carbon budget"
• Every fuel purchase, flight, or red meat purchase would be debited
• Exceeded quota? Purchase blocking or automatic surcharge
• The CBDC would track every transaction and calculate the footprint in real time

What it is presented as: An ecological measure. What it actually is: Total control over consumption behavior.

Theoretical Examples (but Technically Possible)

Beyond current tests, here is what a CBDC could do:

• Block purchases of certain products (tobacco, alcohol, weapons)
• Limit fuel purchases based on your quota
• Ban donations to certain organizations or parties
• Block purchases abroad or in foreign currencies
• Force spending in certain sectors ("buy local")
• Limit withdrawals or transfers to other countries
• Dynamically adjust your limits based on your social "score"

3. Negative Interest Rates

Currently, if banks impose negative rates, you can withdraw your money as cash. With a CBDC and the disappearance of cash, this option vanishes.

Possible scenario:

• The ECB imposes a -2% rate on CBDC deposits
• Your balance of €10,000 becomes €9,800 in one year
• You cannot withdraw as cash (it no longer exists)
• You are forced to spend or invest

This is the "efficient" monetary policy some economists dream of.

4. Money Expiration

The digital yuan has already experimented with money with expiry dates:

• You receive €100 in aid
• It must be spent within 3 months
• After that, the money disappears

Official justification: Stimulate consumption. Reality: Force behavior, prevent saving.

5. Instant Account Freezing

We saw it with the Canadian trucker convoy: governments can already freeze bank accounts. With a CBDC, it would be:

• Faster (one click)
• Broader (all your funds, not just one account)
• More permanent (no cash alternative)

A political dissident, an inconvenient journalist, or simply someone who protests, could be financially annihilated in seconds.

Expert Warnings (2025)

Experts warn: unprecedented control in human history.

Dr. Patrick Schueffel — "Unprecedented Surveillance"

Dr. Patrick Schueffel, professor of finance and fintech expert, sounds the alarm:

"With a CBDC infrastructure such as that underpinning the digital euro, a technology will be deployed that can be used for surveillance and control like no other in human history."

Human Rights Foundation — "Threats to Fundamental Rights"

According to the Human Rights Foundation, CBDCs pose major risks:

German Informatics Society (GI) — "The Transparent Citizen"

The Gesellschaft für Informatik (German equivalent of a Computer Science Society) warns against the "Gläserner Mensch" — the "glass citizen":

"The introduction of a digital euro and the simultaneous decline of cash constitute a threat to informational self-determination and privacy."

The US vs Europe Contrast

Remarkably: the United States blocked the introduction of a digital dollar.

Argument of American legislators:

"Money must be free from political manipulation and government surveillance."

Meanwhile, European decision-makers have not paused to reflect on these implications. The project continues at full speed.

Possible "Orwellian" Features

According to experts, the underlying technology would enable features that "border on the Orwellian":

• Automatic expiry dates on money
• Spending limits by category
• Real-time spending tracking
• Financial behavior monitoring
• Geographic restrictions on payments

"Although these possibilities are downplayed in official central bank communications, they could very well be integrated into the design of the digital euro."

Arguments in Favor of CBDCs

Inclusion, efficiency, fraud prevention: the official promises.

To be balanced, here are the arguments put forward by CBDC proponents:

1. Financial Inclusion

Argument: CBDCs would allow the unbanked to access digital payments.

Counter-argument: The unbanked already have access to solutions (mobile money, cash). CBDCs would surveil them where they were previously free.

2. Payment Efficiency

Argument: Instant payments, 24/7, without banking intermediaries.

Counter-argument: SEPA Instant already offers this. Bitcoin and Lightning do too. No need for a CBDC.

3. Fraud Prevention

Argument: Total traceability would reduce tax fraud and money laundering.

Counter-argument: Mass surveillance of honest citizens to catch a minority of fraudsters is disproportionate. Major fraudsters will find other means.

4. Targeted Monetary Policy

Argument: Being able to send aid directly to citizens, bypassing banks.

Counter-argument: This works both ways — also being able to confiscate directly.

5. Monetary Sovereignty

Argument: Competing with the dollar, Bitcoin, and private stablecoins.

Counter-argument: State sovereignty should not come at the expense of citizen freedom.

Bitcoin: The Sovereign Alternative

A currency that no one controls, censors, or confiscates.

Facing the risks of CBDCs, Bitcoin represents a fundamentally different alternative.

Protective Properties

Bitcoin's Limitations as Protection

Let's be honest about the challenges:

Volatility: Bitcoin remains volatile, making it difficult as a daily currency.

Learning curve: Using Bitcoin correctly requires education.

Entry/exit points: Exchanges are regulated and can refuse clients.

On-chain traceability: Bitcoin transactions are public (though pseudonymous).

Regulatory pressure: States can make using Bitcoin increasingly difficult.

The Best of Both Worlds?

Some envision a future where:

• CBDCs are used for "official" transactions (taxes, salaries)
• Bitcoin is used for savings and private transactions
• Both coexist, offering choice to citizens

This optimistic scenario assumes that states tolerate this coexistence. History suggests they might rather seek to eliminate competition.

How to Prepare?

Learn Bitcoin now, defend cash, diversify your holdings.

Practical Strategies

1. Learn to Use Bitcoin Now

When CBDCs are deployed, learning will be more difficult (increased surveillance, potential restrictions).

Actions:

• Create a Bitcoin wallet
• Buy a small amount
• Practice transactions
• Understand self-custody

2. Diversify Your Holdings

Don't put all your eggs in one basket:

• Traditional bank account (necessary for daily life)
• Physical cash (last bastion of privacy)
• Bitcoin (sovereign store of value)
• Physical gold (traditional alternative)

3. Understand Self-Custody

Your bitcoins on an exchange can be seized or frozen. Your bitcoins on a hardware wallet with a recovery phrase that only you know are safe.

Invest in a hardware wallet and learn to use it.

4. Defend Cash

Cash is the last legal anonymous payment method. Its disappearance would set a dangerous precedent.

Citizen actions:

• Continue using cash
• Support merchants who accept it
• Politically oppose its elimination
• Raise awareness among those around you

5. Stay Informed and Inform Others

The best defense is an informed population that understands the stakes. Share this information with those around you.

FAQ: Your Questions About CBDCs

Will the digital euro replace cash?

The ECB claims that the digital euro will coexist with cash. But:

• Cash is expensive to manage (printing, transport, security)
• Digital payments are more traceable
• The global trend is toward the disappearance of cash
• Today's guarantees can change tomorrow

Officially: coexistence. Practically: cash will be gradually marginalized.

Are CBDCs on blockchain?

Generally no. Most CBDCs do not use a decentralized blockchain.

They use centralized distributed ledgers (permissioned DLTs) entirely controlled by the central bank.

"Blockchain" technology is used as a marketing term, but the principle of decentralization is absent.

Can I refuse to use a CBDC?

Theoretically yes, practically it will depend:

• If cash is eliminated, no alternative for legal payments
• If salaries and taxes are in CBDC, no choice
• If merchants are forced to accept it, no escape

Bitcoin offers an exit door from the system, but its use could be made difficult.

Are CBDCs safer than cryptocurrencies?

"Safer" for whom?

• For the state: Yes, total control
• For banks: Yes, maintaining their role
• For your purchasing power: No, same inflation as the current euro
• For your privacy: No, increased surveillance
• For your freedom: No, possible spending control

CBDCs are "safe" in the sense that you won't lose your money in a hack. But you could lose it through legal confiscation or inflation.

Can Bitcoin be banned when CBDCs arrive?

Technically, banning Bitcoin is very difficult:

• Decentralized global network
• No central server to shut down
• Satellite, mesh, and radio transactions possible

Practically, states can:

• Ban exchanges (already done in China)
• Block fiat gateways
• Make usage illegal (with penalties)
• Monitor on-chain transactions

A total ban is unlikely in democracies, but regulatory friction is certain.

Are there "good" CBDCs?

A privacy-respecting CBDC is theoretically possible:

• Anonymous transactions up to a threshold
• No restrictive programmability
• No expiration
• Guaranteed coexistence with cash

Some projects (like Switzerland's) explore more respectful CBDCs.

But the power of surveillance being too tempting, it is unlikely that states will resist in the long term.

Conclusion: Two Visions of the Future

CBDCs and Bitcoin represent two possible futures for money:

The CBDC Future

• Total transaction surveillance
• Possible spending control
• Monetary policies "optimized" (for the state)
• Disappearance of financial privacy
• Citizens dependent on the state's goodwill

The Bitcoin Future

• Pseudonymous and non-censorable transactions
• Fixed supply protecting purchasing power
• Self-custody impossible to seize
• Individual financial freedom
• Citizens sovereign over their money

The Choice

The battle between these two visions is underway. It will play out:

• In legislation (crypto regulation, cash protection)
• In adoption (how many people use Bitcoin)
• In technology (privacy improvements)
• In collective awareness (understanding of the stakes)

Your role:

• Inform yourself about CBDCs and their implications
• Learn to use Bitcoin as an alternative
• Defend cash and anonymous payment methods
• Share this information with those around you

The future of money is not yet written. But it is being decided now.
