# How is Bitcoin different from bank money?

A bank balance is a promise from your bank; self-custodied bitcoin is controlled directly by your keys. Compare freezing, supply, fees and reversals.

## What a bank balance really is
> Diagram: A bank payment passes through middlemen who can delay, block or reverse it — You → !Your bank: can freeze → Clearing: networks → Their bank → Recipient

> Diagram: A Bitcoin payment goes from your keys to the network, final once confirmed — *You: sign with your key → Network: thousands of nodes → Block: confirmed → Recipient: final

Your bank balance is a number in your bank's database: a promise that the bank owes you that money. The bank can freeze it, reverse payments, or limit withdrawals, and it decides who can open an account.

## What holding bitcoin is
Bitcoin you hold yourself isn't owed to you by anyone. It's recorded on the public [blockchain](https://mybitcoinexplorer.com/learn/what-is-the-blockchain) as spendable by your [keys](https://mybitcoinexplorer.com/learn/private-keys). Nobody can move it without those keys, and nobody can stop you moving it if you have them.

| | Bank money | Bitcoin (self-custody) |
|---|---|---|
| Who keeps the record | Your bank | Every [node](https://mybitcoinexplorer.com/learn/what-is-a-bitcoin-node) |
| Who can freeze it | The bank or authorities | No one, without your keys |
| Supply | Can grow over time | Fixed at about [21 million](https://mybitcoinexplorer.com/learn/bitcoin-supply-21-million) |
| Reversals | Possible (chargebacks) | Not after confirmation |
| Opening hours | Business days, cut-off times | Always on, 24/7 |
| If you lose access | The bank can reset your password | Lost keys mean lost coins |

## The trade-off
Self-custody gives you control, but also full responsibility. There is no help desk if you lose your [seed phrase](https://mybitcoinexplorer.com/learn/seed-phrases-bip39). Many people keep bitcoin on an exchange, which works more like a bank account. See [Self-custody vs custodial](https://mybitcoinexplorer.com/learn/self-custody-vs-custodial).


## Moving money abroad
Sending money internationally through banks can take days and pass through several intermediaries, each taking a fee and able to delay it. A Bitcoin payment costs the same to a neighbour or another continent, settles in about the same time, and works on weekends and holidays.

## Where banks are better
To be fair:
- **Mistakes can be fixed.** Banks can reverse fraud; Bitcoin can't.
- **Deposit insurance** protects many bank balances; nothing insures self-custodied bitcoin.
- **Price stability:** a bank balance holds its face value; bitcoin's price moves a lot.

Many people use both: a bank for daily spending, bitcoin as savings they control themselves.


## Key takeaways

- A bank balance is the bank's promise; self-custodied bitcoin is controlled directly by your keys.
- Confirmed Bitcoin payments can't be reversed or frozen by a third party.
- With control comes responsibility: lost keys can't be recovered.

## Common questions

### Is bitcoin on an exchange the same as owning bitcoin?

Not quite. The exchange holds the keys and owes you the balance, much like a bank.

### Can a Bitcoin payment be refunded?

Only if the receiver sends a new payment back. There is no built-in chargeback.

### Can the government freeze my bitcoin?

Bitcoin held with your own keys can't be frozen on the network. Bitcoin held on an exchange can be frozen by the exchange.

### Are Bitcoin payments cheaper than bank transfers?

Often for international payments. Fees depend on how busy the network is, not on the amount or the distance.
