ABOUT
About Bitcoin (BTC)
Bitcoin is a decentralized digital currency that allows people to transfer value through a global peer-to-peer network without relying on a central bank or payment company. It was introduced in a 2008 whitepaper by the pseudonymous Satoshi Nakamoto and launched in January 2009.
The network uses blockchain technology and Proof of Work to record and verify transactions. Miners process transactions and secure the network in return for block rewards, while Bitcoin’s fixed maximum supply of 21 million BTC and scheduled halvings control how new coins enter circulation.
Learn about Bitcoin’s origins, how the network operates and how BTC is used today. This profile follows its development from an experimental electronic cash system into a globally traded digital asset, while explaining its supply model, mining process, uses, risks and continuing role in the financial system.

Bitcoin at a Glance
Bitcoin is the first decentralized cryptocurrency, introduced by the pseudonymous Satoshi Nakamoto in a 2008 whitepaper. This profile covers its origins, purpose, supply model and the network structure behind BTC.

When Was Bitcoin Created?
Bitcoin was introduced on October 31, 2008, when Satoshi Nakamoto published a whitepaper proposing a peer-to-peer electronic cash system. The network launched with the Genesis Block on January 3, 2009.
Nine days later, Satoshi Nakamoto sent 10 BTC to Hal Finney in Bitcoin’s first recorded person-to-person transaction. These milestones mark Bitcoin’s progression from an idea to an operating payment network.
Bitcoin Network Launched
The Genesis Block, also known as block zero, launched the Bitcoin blockchain and began its recorded transaction history.
First Bitcoin Transfer
Satoshi Nakamoto sent 10 BTC to Hal Finney in the first recorded person-to-person transaction on the Bitcoin network.

Bitcoin Evolution
Bitcoin evolution has taken the network from an experimental electronic cash system to an established digital asset with payment, trading, and investment infrastructure. The underlying network remains decentralized, but the ways people access, use and trade Bitcoin have expanded considerably since its early years.
Several developments mark this transition. Commercial use demonstrated that Bitcoin could be exchanged for physical goods, scheduled halvings altered the rate of new supply and regulated financial products connected Bitcoin with traditional markets. These milestones show how Bitcoin’s role has evolved without changing its maximum supply or reliance on Proof of Work.
Bitcoin Was Used to Purchase Physical Goods
Laszlo Hanyecz reported trading 10,000 bitcoins for two pizzas in May 2010. The transaction became the earliest widely documented purchase of physical goods using Bitcoin.
Bitcoin Completed Its First Halving
Bitcoin’s first halving occurred after block 210,000. The block subsidy declined from 50 BTC to 25 BTC, following the issuance schedule built into the Bitcoin protocol.
Regulated Bitcoin Futures Launched
CME Group launched cash-settled Bitcoin futures on December 18, 2017. The contracts gave eligible market participants a regulated way to gain price exposure and manage Bitcoin-related risk without directly holding BTC.
US Spot Bitcoin Products Were Approved
The US Securities and Exchange Commission approved the listing and trading of multiple spot Bitcoin exchange-traded products on January 10, 2024. These products expanded the ways investors could gain regulated exposure to Bitcoin through traditional brokerage and securities-market infrastructure.
Understanding Bitcoin
How Does Bitcoin Work?
Bitcoin works through a peer-to-peer network that maintains a shared public record of confirmed transactions. Bitcoin wallets store the private keys used to authorize transfers, while the network checks that each transaction follows the protocol’s rules and does not attempt to spend the same Bitcoin twice.
Miners collect valid pending transactions into blocks and compete to produce the required Proof of Work. A completed block is broadcast to the network, where independently operated nodes verify it before accepting it as part of the blockchain. Additional blocks provide further confirmation that an earlier transaction has been recorded.
01
Sign the Transaction
The sender’s wallet uses a private key to authorize the transaction.
02
Broadcast to the Network
The signed transaction is shared with participating Bitcoin nodes.
03
Verify the Transaction
Nodes check the transaction against Bitcoin’s consensus rules.
04
Confirm in a Block
A miner includes the transaction in a block that nodes verify and add to the blockchain.
What Shapes Bitcoin’s Price?
Bitcoin’s price is determined by supply and demand across the markets where BTC is traded. Its issuance follows a predictable schedule, but the quantity available for sale depends on existing holders, while demand changes as market participants buy, sell or retain Bitcoin.
Liquidity, trading activity, regulatory developments, institutional investment products, market sentiment and broader financial conditions can all influence demand and short-term price movements. These forces operate across different platforms, which is why Bitcoin prices can vary slightly between exchanges at the same moment.
Bitcoin Supply
Bitcoin has a limited issuance schedule, and the number of new bitcoins created through mining decreases following each halving.
Market Demand
Demand can change as individuals, companies, funds and other market participants increase or reduce their Bitcoin exposure.
Market Liquidity
Markets with less available liquidity may experience larger price movements when substantial buy or sell orders are placed.
Regulation
Regulatory decisions can affect where Bitcoin is traded, how financial companies provide access and which investors can use particular Bitcoin products.
Institutional Flows
Purchases and sales connected to funds, exchange-traded products and other institutional vehicles can add to market demand or selling pressure.
Financial Conditions
Changes in risk appetite and global funding conditions may influence how much capital investors allocate to volatile assets such as Bitcoin.
What’s the Price of Bitcoin?
Bitcoin is currently priced at $83,845.36 USD, down 0.46% over the past 24 hours. The live Bitcoin Snapshot above provides additional BTC market data.
Will Bitcoin Go Back Up?
No one can know with certainty whether Bitcoin will go back up after a price decline. Previous recoveries do not guarantee future performance, and Bitcoin can remain below an earlier record for an extended period.
Is Bitcoin Dead?
No. Bitcoin remains an active network supported by independently operated nodes and miners that validate transactions and add new blocks. A falling Bitcoin price does not mean the network has stopped operating, although continued network activity does not guarantee future adoption, demand or price recovery.
Can You Cash Out Bitcoin for Real Money?
Yes. Bitcoin can be sold for government-issued fiat currency, such as US dollars or euros, through a supported exchange or financial service. The available currencies, withdrawal methods and service providers depend on the user’s location and the rules that apply in that jurisdiction.
The amount received depends on the Bitcoin price when the sale is executed, the quantity sold and any trading, conversion, network or withdrawal fees. A service may also require identity verification before it allows Bitcoin to be sold or funds to be withdrawn.
Choose a Supported Service
Select a service that supports Bitcoin sales and withdrawals in the required fiat currency. Check whether the provider operates in the relevant jurisdiction and review its fees, limits and verification requirements.
Transfer the Bitcoin
Send the BTC to the deposit address provided by the service. Confirm the address and transfer method carefully before approving the transaction because confirmed Bitcoin transfers generally cannot be reversed by a bank or payment provider.
Sell BTC for Fiat Currency
Place an order to sell the Bitcoin for a supported currency. The final exchange rate may depend on the order type, available market liquidity and the price at which the trade is completed.
Withdraw the Funds
Withdraw the proceeds through an available bank account, card or other supported payment method. Processing times, withdrawal limits and fees vary between providers and jurisdictions.
Cash-Out Checklist
Before You Cash Out Bitcoin
Before you cash out Bitcoin, compare the service’s availability, verification requirements, total fees and expected processing time. These details can affect how much money you receive, how quickly it arrives and whether the withdrawal can be completed in your location.
Confirm every wallet address and transfer method before sending BTC, and keep records of the sale, fees and funds received. Bitcoin transfers generally cannot be reversed once confirmed.
