The 15 Most Common Bitcoin Myths Fact-Checked

Are the common Bitcoin myths true? Mostly not, but almost every one has a grain of truth. Bitcoin is not anonymous, not hacked, not endlessly expandable and not mainly a tool for criminals. What is true: the price swings hard, the network uses a lot of electricity, and if you lose your keys, you lose your bitcoin. Here are 15 claims checked with figures.

"That's just for drug dealers." "It'll burst anyway." "It uses more electricity than a whole country." If you talk about Bitcoin, you will almost certainly hear these sentences. Maybe you think them yourself. Some are wrong, some half true. This fact check tests each one with figures and sources so you can judge for yourself. What Bitcoin actually is, is explained in the beginner's guide What is Bitcoin?.

The 15 Bitcoin myths at a glance

Myths about crime and security

1. "Bitcoin is only for criminals"

Criminals use bitcoin the way they use cash, bank accounts and gold. But the share is small. According to Chainalysis, about 0.14% of all crypto payments in 2024 went to known illicit addresses, and that already includes stablecoins and other coins. For comparison: the United Nations estimates that 2 to 5% of global economic output is laundered every year, mostly in traditional money.

For criminals, bitcoin also has a big drawback: every payment stays in the blockchain, public forever. Investigators can still trace it years later.

2. "Bitcoin is anonymous"

Bitcoin is pseudonymous, not anonymous. The blockchain contains no names, but it does contain every address and every amount. As soon as an address is linked to a person, for example through an exchange with ID checks, their money flows can be traced.

Two cases from the files of the US Department of Justice: in 2021 the FBI recovered 63.7 BTC of ransom from the attack on the Colonial Pipeline. In 2022 investigators seized about 94’000 BTC from the 2016 Bitfinex hack. Both succeeded because the trail was in the blockchain.

3. "Bitcoin has been hacked"

The Bitcoin network itself has never been cracked. Nobody has ever forged a signature or moved someone else's bitcoin without the key. There was one serious bug: in August 2010 a calculation error created 184 billion bitcoin out of nothing. Satoshi delivered a fix within a few hours, and the false coins do not exist today.

What got hacked were exchanges and services that held bitcoin for their customers, above all Mt. Gox in 2014. Anyone who kept bitcoin there owned only a promise from the exchange. What follows from these collapses is shown in Crypto exchange bankrupt: what you can learn from Mt. Gox to FTX.

4. "Bitcoin is backed by nothing"

True: there is no vault, no state and no company behind Bitcoin. But the same applies to the euro and the franc. Since 15 August 1971 the dollar can no longer be exchanged for gold, and so no other major currency system is tied to gold any more either. The euro and the franc are worth something because people and the state accept them.

Bitcoin is worth something because people value its properties: the supply is fixed, nobody can increase it, and you can own bitcoin without a bank and send it worldwide. How bitcoin, gold and the euro score on these properties is shown in What is good money?.

Myths about price and value

5. "Bitcoin is a bubble and will soon be dead"

The site 99Bitcoins counts over 400 obituaries for Bitcoin in newspapers and blogs. Bitcoin has been running without interruption since January 2009. There have still been crashes, and severe ones. This is what the big declines looked like in dollars:

Daily closing prices from the site's data, as of Nov 13, 2026.

A bubble in the classic sense rises once and never comes back. Bitcoin has reached a new high after every crash, so far. Nobody can promise that it will continue.

The Power Law model describes the long-term trend. Its lower line, the floor, was close to the actual price at the lows of 2015 and 2022. On Nov 13, 2026 one bitcoin costs $68’235, which is 0.63 times the trend and just above the floor.

Where the floor lies on any given date is calculated by the floor calculator.

6. "Bitcoin is pure speculation"

Many people buy bitcoin to sell it at a higher price. That is speculation, as with any share. It is also true that the price swings much more than shares or gold. But the swings are shrinking over the years. The annual volatility, calculated from the site's daily prices:

For people in countries with high inflation or without a reliable bank, bitcoin is not speculation but a way to hold their savings. If you hold for years and buy regularly, you are not speculating on next month.

7. "It's too late for Bitcoin, it's too expensive"

On Nov 13, 2026 one bitcoin costs about €61’580 or CHF 56’850. But you don't have to buy a whole one. One bitcoin has 100 million sats. For €50 you get about 81’000 sats, for CHF 50 about 88’000 sats.

Whether it is "too late" depends on how many people will hold bitcoin in future. The price of a whole coin says nothing about that. Why the unit doesn't matter is explained in Sats explained: why you don't need a whole bitcoin.

Myths about the environment, the state and technology

8. "Bitcoin is destroying the climate"

Bitcoin uses a lot of electricity. The Cambridge Centre for Alternative Finance most recently estimated 138 TWh a year, about 0.5% of the world's electricity. According to its survey of miners, 52.4% of it comes from hydro, wind, solar and nuclear power, and only 8.9% from coal.

The electricity is not a side effect but the network's protection: anyone wanting to forge the blockchain would have to do more computing work than all honest miners combined. Headlines such as "one transfer uses as much as a household in two months" calculate wrongly, because a block costs the same electricity no matter how many payments it contains. All the figures are in the fact check on Bitcoin's energy use.

9. "The state can simply ban Bitcoin"

A state can ban exchanges, banks, mining and payments within its own borders. China did so in 2021. The network kept running, and the miners moved to other countries. A single state cannot switch Bitcoin off, because the computers are spread all over the world.

In Germany, Austria and Switzerland, Bitcoin is legal and regulated. The EU has created its own rules for crypto assets with MiCA, Switzerland with its DLT Act. What a ban could achieve is in Can Bitcoin be banned?.

10. "Quantum computers will soon crack Bitcoin"

A sufficiently large quantum computer could calculate the private key from a public key. Mainly at risk would be coins whose public key is already in the blockchain: according to Glassnode, 35.4% of all bitcoin (as of Nov 10, 2026).

That machine doesn't exist yet. Estimates from 2026 put the requirement at 20’000 to 500’000 physical qubits; the best machines today have around 100 very accurate ones. Developers are working on quantum-safe addresses. The current state and what you can do today is shown in Quantum computers and Bitcoin.

11. "Bitcoin is too slow for payments"

Half true. A new block comes on average every ten minutes, and a block holds a few thousand payments. For a coffee at the till that is too slow. For large amounts that need to arrive worldwide without a bank and at the weekend, it is fast.

For everyday payments there is the Lightning Network. There a payment arrives in seconds and usually costs 1 to 10 sats. You pay with real bitcoin, just outside the blockchain.

Myths about rules and ownership

12. "More bitcoin can be created at any time"

No. Each new block may only contain a fixed amount of new bitcoin, and this halves roughly every four years. Together that adds up to just under 21 million. As of Nov 13, 2026 there are about 20.11 million, 95.8% of the final supply.

Every node checks every block. A miner who pays itself more bitcoin is ignored by all the others. How this works in detail is explained in Why there are only 21 million bitcoin.

13. "Someone controls Bitcoin"

There is no company, no boss and no headquarters. The inventor, Satoshi Nakamoto, withdrew in 2011. His roughly 1.1 million bitcoin from the first blocks have never moved. More on this in Satoshi Nakamoto and the origins of Bitcoin.

Developers propose changes, but every node decides for itself which software it runs. Miners order payments into blocks but cannot change any rules. Anyone who wants to change the rules has to convince the users. That is why Bitcoin changes slowly, and why many people trust it.

14. "Your bitcoin are in your wallet"

Your bitcoin are in the blockchain. The wallet only holds the key with which you can move them. Two things follow from this:

1. If your device breaks, your bitcoin are not gone. With your seed, the 12 or 24 words, you restore the key in another wallet.
2. If you lose both the seed and the device, they are gone. There is no bank to reset a password.

How to set up your first own wallet and back up the seed is shown in Setting up a bitcoin wallet.

15. "You always pay tax on bitcoin gains"

That depends on where you live (as of 2026):

Buying and holding does not trigger a tax on gains in any of the three countries. The rules for Germany in detail, with worked examples, are in Bitcoin taxes in Germany.

What is true about the myths

Behind most myths there is a real risk you should know about:

• The price can halve, and more than once. Only buy what you won't need for years.
• Mistakes are final. A lost seed or a payment to scammers cannot be reversed.
• Exchanges can go bust. Larger amounts belong in your own wallet.

If you decide how much you buy and how long you hold before the price puts you under pressure, you are prepared for most of these risks. My Goal helps you with that.
