Bitcoin (BTC) price and market data
Layer 1 network · Proof of Work
Short answer: Bitcoin is the first decentralized digital currency, with a fixed 21 million supply and proof-of-work security. The panel below loads its live price, market cap, volume, supply, and 24h/7d/30d performance from named public sources with the as-of time printed on it. The sections after it explain what Bitcoin is and how it works, without quoting prices that would go stale.
What is Bitcoin?
Bitcoin is the first decentralized digital currency, running since January 2009. It lets people send value to each other over the internet without a bank or payment company in the middle. Transfers are recorded on a public ledger, the blockchain, that thousands of independent computers keep in sync and anyone can audit.
BTC, the network's native asset, has a fixed maximum supply of 21 million coins. New coins enter circulation only as rewards to miners, and that reward halves roughly every four years, so issuance slows on a published schedule rather than by anyone's decision. That fixed, predictable supply is the core of the design, and it is why treasuries, funds, and public companies have adopted BTC as a reserve asset.
How Bitcoin works
- Miners compete to add blocks of transactions roughly every ten minutes, using proof of work (the SHA-256 hashing race) to make history expensive to rewrite.
- Every 210,000 blocks the block reward halves; it started at 50 BTC per block and declines toward zero, so total supply never exceeds 21 million.
- Transactions spend earlier outputs (the UTXO model). A payment is valid only if it references unspent outputs, which is how the ledger prevents double spending without a central operator.
- The network adjusts mining difficulty about every two weeks to keep block times near ten minutes as computing power joins or leaves.
The risk, in plain terms
BTC's price has repeatedly fallen 50 percent or more within a year. Nothing backs it except the network's continued operation and market demand.
Every figure on this page comes from the named public source printed beside it. If a feed fails, the panel says so instead of presenting old numbers as live. Read the methodology for how CryptosEyes sources market data, and the disclaimer before acting on anything you read here.
Bitcoin in Weekly Movers
In the Weekly Movers snapshot for the week ending October 3, 2026, Bitcoin changed +1.07% over seven days at rank #1 by market cap (frozen snapshot, CoinGecko public market data (coins/markets, USD, market-cap order)). Bitcoin is one of the two benchmark coins the desk reports every week regardless of whether it made the top-10 movers lists.

Bitcoin ETFs return to inflows as leverage builds into soft US jobs data
US spot Bitcoin ETFs took in $102.7 million on October 1 on the strength of one large fund, Ether funds kept bleeding, and derivatives leverage climbed into a soft jobs report that first lifted Bitcoin toward $87,000 and then gave the move back.

The SEC approved a Cboe listing rule for six triple-leveraged products, including the first US-listed 3x Bitcoin and Ether ETPs, but trading waits on a separate registration step, and the daily reset changes what triple leverage actually delivers.

Frequently asked questions
What is the current price of Bitcoin?
The live panel at the top of this page shows the latest BTC price in US dollars, loaded in your browser from the CoinGecko public market API with the CoinPaprika public API as fallback. It refreshes about every two minutes while the page is open and prints its source and as-of time beside the figures. An aggregator price is a market-wide average across exchanges; a single exchange can quote slightly higher or lower at the same moment.
How is Bitcoin's market cap calculated?
Market capitalization is the current price multiplied by the circulating supply, the amount of BTC in public hands as reported by the data source. Where the source publishes total and maximum supply, this page shows those beside the circulating figure so the gap is visible. Market cap values the circulating coins at today's price; it is not the amount of money anyone has invested in the asset, and it moves whenever either the price or the reported supply changes.
Is BTC a good investment?
CryptosEyes does not make that call for any asset. This page publishes market data with named sources and explains how Bitcoin works, so you can judge it against your own research. The risk to understand first: BTC's price has repeatedly fallen 50 percent or more within a year. Nothing backs it except the network's continued operation and market demand.
