Bitcoin is now on MetaMask
One home, many chains.

Bitcoin (BTC) is the world's first decentralised digital currency and the foundation of crypto's global ecosystem. Created in 2009 by the pseudonymous developer Satoshi Nakamoto, Bitcoin introduced a peer to peer payment system that eliminates the need for banks or intermediaries. Every Bitcoin transaction is verified and recorded on the blockchain, a transparent and immutable ledger accessible anywhere in the world.
Unlike traditional currencies controlled by central banks, Bitcoin operates on a limited supply model capped at 21 million coins, making it inherently scarce and deflationary. New BTC are issued through mining, a process where global participants use computational power to validate transactions and secure the blockchain. This proof‑of‑work (PoW) system ensures that Bitcoin remains secure, censorship resistant, and decentralised.Often referred to as digital gold, Bitcoin is used worldwide as a store of value. It powers everything from direct payments to decentralised finance (DeFi) applications, and wrapped Bitcoin products (like WBTC and tBTC) that bring BTC liquidity into other blockchain ecosystems such as Ethereum and Solana.
As an open source network, Bitcoin's development and governance are maintained by a distributed community of engineers, miners, and users. Network upgrades and optimisations are proposed through transparent Bitcoin Improvement Proposals (BIPs), preserving both technical stability and global neutrality.

Short-term momentum is present as Bitcoin trades at $70,570 (+1.03% 24h). Session gains reported up to +2.1% coincided with equities, indicating demand spillover. (Source)
Bitcoin's circulating supply crossed 20 million BTC this week, leaving roughly 1 million left to mine over the next ~114 years. The milestone has renewed media attention on Bitcoin's fixed-supply design as a differentiator from inflationary assets. (Source)
Scarcity narratives persist as on-chain data shows a significant share of Bitcoin supply has not moved in over a year. With BTC trading near or below estimated miner production costs (~$70,000), the market is in a range that has historically coincided with miner capitulation phases and and periods of reduced new supply entering exchanges.

Tight monetary conditions persist as the Fed holds rates steady amid geopolitical uncertainty. Arthur Hayes noted he is waiting for central bank liquidity expansion before buying, raising questions about the pace of institutional re-entry. (Source)
Geopolitical uncertainty continues to weigh on risk assets as ongoing conflicts sustain elevated oil prices. BTC has historically correlated with equities during macro stress events, and prolonged instability could delay the institutional inflows that many analysts expect to drive the next leg higher.

Fraud using Bitcoin payments remains active, with a $79,000 victim traced via wallet transfers. Persistent impersonation scams may prompt stricter KYC enforcement and slower onboarding. (Source)
