What Is Bitcoin? BTC Explained, Value & Risks

What Is Bitcoin?

Bitcoin is a decentralized payment network, protocol and digital asset. The term Bitcoin, with a capital B, commonly refers to the network and protocol. Bitcoin, bitcoin or BTC may also refer to the network's native unit, depending on context.

Bitcoin was introduced as a peer-to-peer electronic cash system that allows online payments to be sent without relying on a traditional financial institution to process every transaction. Its network uses proof-of-work mining to confirm transactions and protect the blockchain's transaction history.

What Is BTC?

BTC is the commonly used ticker symbol for bitcoin — the native asset of the Bitcoin blockchain. It is used to:

Transfer value
Pay transaction fees
Reward miners
Participate in the Bitcoin economy
Hold an asset independently through a compatible wallet

Bitcoin can be divided into smaller units. The smallest unit recorded by the Bitcoin blockchain is called a satoshi. One bitcoin equals 100 million satoshis.

Is Bitcoin a Coin or a Token?

Bitcoin is generally classified as a coin because BTC is the native asset of the Bitcoin blockchain. It is not a token created through a smart contract on another blockchain.

However, tokenized representations of Bitcoin can exist on other networks. These wrapped or bridged assets are not identical to native BTC held on the Bitcoin blockchain. They can introduce additional issuer, custodian, bridge or smart-contract risks.

What Gives Bitcoin Value?

Bitcoin does not represent ownership in a company and does not produce corporate earnings. Market participants may value it based on factors such as:

Limited protocol-controlled issuance
Network adoption
Transferability
Liquidity
Security history
Decentralized operation
Recognizability
Demand for an asset outside traditional payment networks
Expectations about future use

Its market price is determined by supply and demand and can change substantially over short periods.

Major Bitcoin Risks

Significant price volatility
Loss of private keys or recovery phrases
Theft or fraud
Custodian or exchange failure
Transaction mistakes
Regulatory changes
Network congestion
Transaction-fee changes
Misleading investment claims
Irreversible transfers

Bitcoin transactions generally cannot be canceled through a bank-style chargeback process once they have been confirmed. Users should verify wallet addresses, networks and transaction details before sending funds.
