The difference between Bitcoin and CBDCs

Our world is becoming increasingly digital, and so is our money.

That begs the question: what do we want our digital money to look like?

Many countries are exploring issuing a Central Bank Digital Currency (CBDC) which is a fully digital form of our existing government currency.

Let's take a look at the difference between two forms of digital money: Bitcoin & Central Bank Digital Currencies (CBDCs).

BITCOIN
Spend without permission
CBDC
Requires permission to spend

Nobody can stop you from transacting with Bitcoin. CBDCs are designed so governments and central banks can control every payment, limiting your privacy and freedom.

BITCOIN
Your money never expires
CBDC
Your money can expire

Bitcoin never expires and has no monthly fees. CBDCs can be programmed to expire, preventing you from saving for the future.

BITCOIN
Fixed supply of 21M BTC
CBDC
No limit on total supply

Bitcoin has a hard cap of 21 million BTC. CBDCs have no cap on supply, allowing governments to expand money at will — which causes inflation.

BITCOIN
Pseudonymous
CBDC
Linked to government ID

Bitcoin addresses aren't tied to your real identity. CBDCs link directly to government ID, enabling mass financial surveillance and censorship.

BITCOIN
Decentralized
CBDC
Centralized

Bitcoin's rules are validated by tens of thousands of independent nodes. CBDCs are centralized in government and central-bank hands, which hold complete control over the network.

BITCOIN
Users can run nodes
CBDC
Users can't run nodes

Anyone can run a Bitcoin node to verify the rules of the network. CBDCs don't allow users to run nodes — you have to trust the central authority.

BITCOIN
Can't be frozen
CBDC
Easily frozen

Self-custodied Bitcoin can't be frozen by anyone. CBDCs are designed so governments and central banks can freeze accounts instantly.

BITCOIN
Can be self-custodied
CBDC
Must trust custodians

Bitcoin gives you full control over your money when you self-custody it with a wallet. CBDCs require trusting custodians like banks or governments to hold your money for you.

BITCOIN
Predictable monetary policy
CBDC
Changing monetary policy

Bitcoin's monetary policy is fixed in code and can't be changed. CBDCs can be reprogrammed at will by politicians, causing inflation when too much money gets printed.

BITCOIN
Secure
CBDC
Insecure

Bitcoin is the most secure computing network ever built and has never been hacked. CBDCs rely on banks and governments that have been hacked countless times.
