Myths & Misconceptions

Bitcoin: myths vs. reality #

Money without central control irritates, provokes, and gets misunderstood. The most common misconceptions, and the facts behind them:

1. “Bitcoin is destroying the environment” #

The misconception: Bitcoin uses too much energy and damages the climate.

The facts: The 2025 Cambridge report estimates annual electricity use at 138 TWh, roughly 0.5% of global consumption. Surveyed mining companies reported a combined 52.4% share of renewables and nuclear energy.

Miners seek cheap energy. Depending on the location, they can use surplus power and respond to grid shortages by switching off.

We weigh the energy use alongside what it enables: an open, censorship-resistant monetary system.

2. “Bitcoin has no intrinsic value” #

The misconception: You can’t touch it, so it’s worthless.

The facts: “Intrinsic value” is itself a misconception. No good has objectively built-in value. Value arises because people find something useful.

What makes Bitcoin useful? Absolute scarcity: a fixed limit of 21 million. Censorship resistance. Sovereignty without permission. Portability: you can carry billions as a seed phrase in your head across any border.

Gold doesn’t have “intrinsic value” either. Its value as money comes from being scarce, durable, and divisible. Bitcoin has the same properties in better form: stricter scarcity, easier transport, simpler divisibility. Plus one property that neither gold nor the euro has: neutrality. No state issues it, no company controls it. Much like the meter is a universal unit of length, Bitcoin has the potential to become a universal unit of value.

3. “Bitcoin is too expensive and too volatile” #

The misconception: One bitcoin costs tens of thousands of euros, and the price swings too wildly.

The facts: 1 bitcoin = 100,000,000 satoshis. You can start with EUR 10. You can buy a gram of gold instead of an entire bar. The price of a whole bitcoin is irrelevant for using small amounts.

Bitcoin’s exchange rate fluctuates sharply. You can lose purchasing power even over longer periods. A limited supply alone does not make the exchange rate stable.

4. “Bitcoin will be banned” #

The misconception: Governments will shut Bitcoin down sooner or later.

The facts: A decentralized network cannot be shut down. Bitcoin runs on tens of thousands of computers worldwide. No central server, no off switch.

A ban can restrict use and access without shutting down the global network. The EU regulates crypto services through the MiCA regulation, whose main provisions apply from 30 December 2024.

The picture is mixed: Texas created a legal framework for a strategic Bitcoin reserve through Senate Bill 21 (2025).

5. “Bitcoin is too slow” #

The misconception: Only 7 transactions per second. Visa handles thousands.

The facts: The Bitcoin blockchain is the network’s shared settlement layer. It transfers money directly, without banks having to settle with each other afterward. A new block arrives every ten minutes on average; further confirmations increase the security of a payment.

For everyday use, the Lightning Network can deliver payments in seconds when sufficient liquidity is available. Fees depend on the route and wallet.

6. “Bitcoin is a Ponzi scheme” #

The misconception: Only early investors profit, like a pyramid scheme.

The facts: In a Ponzi, a central entity pays returns from new investors’ money. Bitcoin has no central entity. Nobody pays “returns.” Nobody promises yields. No multi-level distribution structure exists.

7. “Only criminals use Bitcoin” #

The misconception: Bitcoin primarily serves money laundering and terrorism financing.

The facts: Cash is more anonymous. Bitcoin transactions are visible on the blockchain, forever, while cash leaves no trace.

The initial Chainalysis assessment for 2024 attributed 0.14% of recorded transaction volume to known illicit activity, with stablecoins accounting for 63% of that illicit volume. The figures cover multiple crypto assets, not just Bitcoin, and are revised later.

8. “An exchange hack means Bitcoin has been hacked” #

The misconception: If a Bitcoin exchange is hacked, the network is insecure too.

The facts: Exchange hacks, phishing and stolen seed phrases concern custody and use. How to protect yourself: the Security Guide.

Bitcoin software can contain critical bugs. In 2018, Bitcoin Core disclosed an inflation and denial-of-service vulnerability. A 51% attack is only one class of attack; high costs do not make every attack impossible or irrational.

Tens of thousands of nodes secure the network, with no single point of failure. Critical protocol updates require broad network consensus. Nobody can push through changes alone.

9. “Bitcoin is a speculative bubble” #

The misconception: Bitcoin is like tulip mania. The bubble will pop eventually.

The facts: Bitcoin has existed since 2009 and gone through several price cycles. Speculative bubbles are possible. Throughout those cycles, the network serves a purpose: people can hold their own money and send it directly to others.

Add network effects: every new user and every new node makes the network more valuable and more resilient. That distinguishes Bitcoin from one-off speculative phenomena.

Speculation and actual use coexist. We value the long-term usefulness of a monetary system that operates without central control.

10. “Bitcoin has no practical use” #

The misconception: Bitcoin is a speculative asset with no real-world utility.

The facts: People use Bitcoin for far more than exchange trading.

Bitcoin is capped at 21 million units. Central banks can expand the money supply; the Bitcoin supply cannot. A recurring purchase plan lets you buy fractions regularly.

With Lightning, you can send money in seconds, worldwide, without SWIFT and without correspondent banks. This matters most where traditional banking infrastructure doesn’t exist or has failed.

Companies worldwide hold part of their reserves in Bitcoin, as a complement to traditional reserves. Civil society organizations use Bitcoin as a donation channel that can’t be cut off by banks. Bitcoin Austria itself is funded exclusively through Bitcoin donations.

So why doesn’t everyone pay with Bitcoin day-to-day? Someone expecting Bitcoin to rise in value may prefer not to spend it. More on practical use for individuals and businesses.

FAQ #

What about quantum computers? #

Sufficiently capable quantum computers could attack parts of Bitcoin’s cryptography. Their timeline is uncertain. A migration would be technically and organisationally demanding, not automatic. NIST is developing post-quantum standards; those standards alone do not solve migration of existing bitcoin holdings.
