What is the Bitcoin cryptocurrency?

Bitcoin is the first decentralized cryptocurrency and the largest crypto asset by market capitalization, ranked #1. Satoshi Nakamoto published the Bitcoin whitepaper on 31 October 2008 and mined the genesis block on 3 January 2009. BTC runs on a Proof-of-Work blockchain secured by SHA-256 mining. Bitcoin serves primarily as a fixed-supply store of value — the "digital gold" thesis — rather than a smart-contract platform.

How many bitcoins are there and what is Bitcoin's maximum supply?

Bitcoin has a fixed maximum supply of 21 million coins, hard-coded and unchangeable by any issuer. More than 95% of that supply has already been mined — the 20-millionth BTC was mined around March 2026. New BTC enters circulation only through mining, at a steadily decreasing rate. An estimated 3–4 million BTC are permanently lost, so the effective tradeable supply sits below the on-chain figure.

Why does Bitcoin have value and what backs it?

Bitcoin is backed by no government, company, or physical commodity — Bitcoin derives value from its monetary properties and network security. A fixed 21 million supply makes Bitcoin scarce, while Proof-of-Work mining across a decentralized node network makes Bitcoin costly to attack and impossible to counterfeit. Bitcoin value also reflects adoption — US spot ETF demand and corporate treasury holdings since 2024 widened the buyer base. No central party can inflate or freeze Bitcoin, which underpins the store-of-value thesis.

What is Bitcoin's all-time high (ATH) price?

Bitcoin reached an all-time high of $126,195.41 on 6 October 2025, per DropsTab price history. The prior cycle peak was near $69,000 in November 2021. Bitcoin's 2025 record followed US spot Bitcoin ETF launches in January 2024 and rising institutional demand. All-time-high figures are historical records and do not reflect Bitcoin's current price, shown live above.

When was Bitcoin created and what was its starting price?

Satoshi Nakamoto released the Bitcoin whitepaper on 31 October 2008 and launched the network with the genesis block on 3 January 2009. Bitcoin had no sale price at launch — early coins were mined, not bought. The first quoted exchange rate appeared in October 2009 at roughly $0.0008 per BTC, set by New Liberty Standard. Bitcoin held no ICO, presale, or investor allocation.

What is the Bitcoin halving and when is the next one?

The Bitcoin halving cuts the mining block reward in half every 210,000 blocks, roughly every four years. Four halvings have occurred — in 2012, 2016, 2020, and 2024. The current reward is 3.125 BTC per block following the April 2024 halving. The next halving is expected around April 2028, reducing the reward to 1.5625 BTC. Each halving slows new supply, tightening Bitcoin's scarcity over time.

How is Bitcoin mined and what consensus secures the network?

Bitcoin uses Proof-of-Work consensus secured by SHA-256 hashing, with miners competing to add a block roughly every 10 minutes. Miners earn the block reward plus transaction fees as compensation. Bitcoin has no staking, no validator allocation, and no insider issuance — every coin enters circulation through mining. As block rewards shrink with each halving, transaction fees increasingly fund Bitcoin's long-term network security.

What is Bitcoin dominance?

Bitcoin dominance measures BTC's share of the total cryptocurrency market capitalization. Traders read Bitcoin dominance as a sentiment signal — a rising figure suggests capital rotating into BTC over altcoins, while a falling figure often marks "altcoin season." Bitcoin holds the #1 market-cap rank across the market. DropsTab tracks Bitcoin's rank and lets users compare BTC against other assets and categories.

Where and how is Bitcoin traded across exchanges?

Bitcoin holds the deepest liquidity of any crypto asset, trading on centralized exchanges, derivative venues, and decentralized markets via wrapped representations. Per DropsTab data, BTC trades across more than 180 spot pairs and 60+ derivative markets, spanning USDT, USD, and major fiat quotes. The Lightning Network enables fast, low-cost off-chain BTC payments. Bitcoin's spread across many high-volume venues makes liquidity fragmentation a negligible risk versus small-cap tokens.

What is the Unisat point farming activity for Bitcoin?

Unisat point farming is an active campaign in the Bitcoin ecosystem, running since February 2023, that rewards users for interacting with Bitcoin through the Unisat Wallet. Participants mint BRC-20 tokens and inscribe .sats names, earning points redeemable toward future rewards. The campaign reflects Bitcoin's Ordinals and BRC-20 activity — token issuance built directly on the Bitcoin base layer. End date is not yet announced.
