Bitcoin White Paper
What Is Bitcoin?
Bitcoin is a decentralized digital currency operating on a public blockchain, independent of banks or single institutions. Anyone can generate a wallet to create a private key (for ownership) and an address (for receiving funds), enabling peer-to-peer transfers. Transactions are secured by cryptography and recorded on the blockchain.
Bitcoin uses a Proof of Work (PoW) consensus mechanism: miners compete using computational power to package transactions and create blocks, earning block rewards and transaction fees. The total supply of Bitcoin is capped at 21 million, making it scarce; it is commonly used for storing value and cross-border payments.
What Are the Current Price, Market Cap, and Circulating Supply of Bitcoin (BTC)?
As of December 25, 2025 (data sourced from platform market feeds), Bitcoin’s price is approximately $87,500.10. The circulating supply is about 19,966,834 BTC, matching the total supply, with a maximum supply of 21,000,000 BTC.
The current circulating market capitalization stands at around $1,747,099,971,683.40, and the fully diluted valuation (FDV) is also about $1,747,099,971,683.40. Because issuance is close to the cap, FDV and market cap are nearly identical. Bitcoin's market dominance is approximately 55.073%, reflecting its share in the overall crypto market.

Who Created Bitcoin (BTC), and When?
Bitcoin was proposed in a whitepaper published in 2008 by the pseudonymous Satoshi Nakamoto. It was launched as open-source software and spread globally through independent network nodes. The genesis block was mined in 2009, marking the official start of the network (referencing public sources: Bitcoin Whitepaper, 2008; Genesis Block, 2009-01-03).
This background explains Bitcoin’s design goals: to build a peer-to-peer electronic cash system independent of banks, while using transparent ledgers and algorithmic rules for issuance and validation.
How Does Bitcoin (BTC) Work?
Bitcoin runs on blockchain technology—a chronological sequence of “blocks,” each recording a batch of transactions and linked by hash pointers for tamper-resistance.
Proof of Work (PoW): Miners compete to find a hash meeting network difficulty targets; the winner earns block proposal rights along with block rewards and transaction fees. Network difficulty automatically adjusts to keep block times around 10 minutes.
Private keys, public keys, and addresses: Private keys authorize transactions via digital signatures; public keys are derived from private keys; addresses are simplified representations for receiving payments. If a private key is lost or compromised, assets become unrecoverable or may be stolen.
Halving mechanism: Block rewards are halved roughly every four years to control issuance rate, contributing to scarcity and supply expectations. Transaction fees (miner fees) are set by users; during network congestion, higher fees may be needed for faster confirmations.
What Can You Do With Bitcoin (BTC)?
Store of Value: With its capped supply and strong network effects, Bitcoin is often seen as “digital gold,” favored for long-term holding and portfolio diversification.
Cross-border Payments and Remittance: Transfers can be made globally without traditional banking channels; costs and speeds depend on network congestion and chosen methods.
Micro-Payments & Scaling: Integrations like Lightning Network enable fast, low-fee micro-transactions; on-chain transfers are suited for larger amounts or higher security confirmation needs.
Collateral & Settlement: In certain compliant contexts, Bitcoin may be used as collateral or a hedging asset; actual usage depends on local regulations and platform policies.
What Are the Main Risks and Regulatory Considerations for Bitcoin (BTC)?
Price Volatility: Crypto asset prices fluctuate due to market supply/demand and macro factors; short-term swings can be significant—manage position sizing and diversify accordingly.

Private Key & Account Security: Loss of private keys is irreversible—always back up mnemonic phrases offline and store securely. For exchange accounts, enable two-factor authentication (2FA), withdrawal whitelists, and anti-phishing codes to guard against social engineering and phishing attacks.
Platform & Counterparty Risks: Centralized custody involves counterparty and compliance risks—regularly audit account security and consider self-custody solutions.
Regulation & Taxation: Compliance requirements, reporting, and tax treatment vary by jurisdiction—follow local laws and retain transaction records.
Network & Fees: Peak periods may cause congestion and fee increases—double-check addresses and run small test transactions to avoid irreversible losses from errors.
What Is the Long-Term Value Proposition of Bitcoin (BTC)?
Scarcity & Rule-Based Supply: Capped at 21 million BTC with a transparent issuance curve governed by halving events—minimizing human intervention risk.
Security & Decentralization: PoW consensus backed by global mining power secures the network; distributed nodes ensure independent record-keeping beyond any single authority.
Network Effects & Liquidity: High market cap and deep liquidity support tradeability and usability, helping Bitcoin serve as a store of value in macro asset allocation.
Macro Narratives & Institutional Adoption: Bitcoin is increasingly included in diversified portfolios amid inflationary pressures and loose monetary policy environments.

Long-term value depends on regulatory developments, infrastructure maturity, and ongoing user education.
How Can I Buy and Securely Store Bitcoin (BTC) on Gate?
Step 1: Register for a Gate account and complete identity verification. Set a strong password, enable two-factor authentication (2FA), and anti-phishing codes to enhance login and transaction security.
Step 2: Fund your Gate account. You can use fiat quick buy or deposit USDT before exchanging it for BTC within the platform. Pay attention to deposit channel fees and processing times.
Step 3: Go to the spot market and search for “BTC/USDT.” Choose between market orders (executed at current prices) or limit orders (executed at your set price), confirm quantity and fees before placing your order.
Step 4: Withdraw to a self-custody wallet for better security. Create a wallet and back up your mnemonic phrase offline (write it down or use encrypted media), test withdrawals with small amounts first, then move larger sums once confirmed.
Step 5: Enable withdrawal whitelists and regularly verify addresses. Whitelists restrict withdrawals to preset addresses—reducing risks of mistakes or theft; always check the network type and address prefixes before each withdrawal.
Step 6: Stay compliant & keep records. Retain transaction receipts and withdrawal records for local reporting or tax purposes—helpful for future reconciliation or audits.
How Does Bitcoin (BTC) Differ From Ethereum?
Purpose & Goals: Bitcoin focuses on robust record-keeping for value storage and payments; Ethereum aims to be a universal smart contract platform supporting complex decentralized applications.
Consensus Mechanism: Bitcoin uses Proof of Work (PoW) secured by mining; Ethereum uses Proof of Stake (PoS), leveraging staking and validator systems for lower energy consumption.
Supply & Economic Model: Bitcoin is capped at 21 million with halving events; Ethereum has no fixed cap—EIP-1559 introduced fee burning so net supply depends on burn rates versus staking amounts.
Feature Complexity: Bitcoin’s scripting language is deliberately limited for security; its mainnet prioritizes simplicity. Ethereum natively supports smart contracts powering ecosystems such as DeFi, NFTs, and diverse protocols.
Fees & Scalability: Bitcoin’s on-chain fees are based on transaction data size—Lightning Network supports fast micro-payments; Ethereum uses a Gas fee model with various Layer 2 solutions boosting throughput.
Summary of Bitcoin (BTC)
