# Bitcoin vs other cryptocurrencies Source URL: https://help.blockstream.com/education/fundamentals/bitcoin-questions/bitcoin-vs-other-cryptocurrencies Updated: 2026-07-29T18:47:06.000Z Category: Fundamentals Section: Common Questions --- **TL;DR:** Bitcoin differs from other cryptocurrencies in kind. It launched in 2009 with no premine, no token sale, and no founder allocation; its 21 million supply cap has never changed; its proof-of-work security has accumulated more computational work than any system in history; and no company or foundation steers its development. Most other digital assets reverse at least one of those properties by design, which changes the trust model an owner accepts. **The comparison in one sentence:** Bitcoin is a neutral monetary network whose rules nobody can change alone, while most other digital assets are projects, with teams, treasuries, and roadmaps, whose rules evolve under identifiable leadership. Neither description is an insult; they describe different engineering goals. This article describes the structural differences by category, so that readers can evaluate any specific asset against them. ## One Word, Two Different Kinds of Thing Thousands of digital assets share the label "cryptocurrency" with Bitcoin, and the shared label obscures how little else they share. Grouping bitcoin with the rest of the digital asset market is like grouping gold with mining-company stocks: the same industry, profoundly different things to own. The differences fall into five structural categories: how the asset launched, how its supply is governed, how the network is secured, who controls its development, and what the protocol is designed to do. Each is examined below. The comparisons describe categories of design, such as proof-of-stake systems or smart-contract platforms, rather than grading individual projects; the goal is a framework, and any specific asset can be measured against it using public information. ## A Launch With No Premine Bitcoin launched on January 3, 2009, when Satoshi Nakamoto mined the [genesis block](https://help.blockstream.com/education/glossary/genesis-block). No coins existed before the network opened, and there was no token sale or allocation to founders or investors. Anyone could mine from the first day under the same rules, and early participants earned coins by contributing the same work later participants did. Satoshi mined alongside everyone else, then disappeared in 2011 without spending the coins attributed to that early mining. The full story is told in [Who Created Bitcoin?](https://help.blockstream.com/education/fundamentals/getting-started/who-created-bitcoin) Most digital assets launched since then follow a different template: a portion of the supply is created at the start and allocated to founders, employees, and venture investors, with the remainder sold to the public or released over time. The practice is legal and openly disclosed in most cases, but its consequence is structural: insiders hold a large, cheaply acquired share of the asset, and the public buys in at prices the insiders set. It also concentrates governance influence wherever token holdings carry voting weight. A fair launch cannot be retrofitted. Whatever else a newer project improves, it cannot reproduce the distribution that comes from starting with zero coins and no privileged parties. Bitcoin's launch happened once, under conditions of total obscurity, and that distribution is part of why no party today holds protocol-level influence over it. ## Fixed Monetary Policy Bitcoin's supply schedule was set in the first version of the software and has never changed: 21 million coins, issued through block rewards that drop by half every 210,000 blocks in the [halving](https://help.blockstream.com/education/glossary/halving). The cap is enforced as a consensus rule by every node, as detailed in Why Is the Bitcoin Supply Limited? Across the rest of the industry, monetary policy is typically a parameter that governance can adjust. Ethereum, the largest non-Bitcoin network, has changed its issuance several times through protocol upgrades, has no fixed supply cap, and burns a portion of fees, so its long-run supply depends on future usage and future governance decisions. Many smaller assets give a foundation or development company explicit authority to mint, allocate, or unlock tokens on a schedule it controls. Adjustable policy is a coherent design choice: a network that pays validators from issuance may need flexibility. But it places holders in a different position. An owner of bitcoin knows the supply schedule to the year 2140 with certainty backed by consensus rules. An owner of an asset with governable issuance holds something whose scarcity depends on decisions other people have not made yet. ## The Deepest Proof-of-Work Security Bitcoin is secured by [proof-of-work](https://help.blockstream.com/education/glossary/proof-of-work): miners spend electricity to find valid blocks, and rewriting history would require redoing that work faster than the honest network extends it. The cumulative [hashrate](https://help.blockstream.com/education/glossary/hashrate) behind Bitcoin exceeds that of every other proof-of-work network combined, by a wide margin, making its settlement assurances the strongest in the industry. Many other networks use proof-of-stake instead, in which validators lock up the network's own token and are penalized in that token for misbehavior. Ethereum, the largest, made this transition in September 2022, documented on the [Ethereum project's own pages](https://ethereum.org/en/roadmap/merge/), and the switch cut its energy use sharply, a real advantage of the model. The trade is in the security model. Proof-of-work anchors the ledger to a resource outside the system: real-world energy and hardware that an attacker must acquire regardless of what happens inside the network. Proof-of-stake designs anchor security to the token itself, which means influence follows token concentration and a party that accumulates enough stake gains power over validation. Neither model is free; they buy different guarantees at different costs, and the comparison is examined in depth in Proof-of-Work vs Proof-of-Stake. Bitcoin's security budget is the largest, its model is the most battle-tested, and its cost of attack is the highest of any digital asset network. ## No Company at the Helm Bitcoin has no CEO and no marketing department, and no foundation holds a treasury or maintains a headquarters for it. Its creator has been absent since 2011\. Development happens in the open across independent contributors and organizations, and no change activates without broad voluntary adoption by node operators, a process described in How Do Bitcoin Upgrades Work? This [decentralization](https://help.blockstream.com/education/glossary/decentralization) of control is what makes Bitcoin's other properties credible: a fixed supply only binds if nobody has the authority to unfix it. Most other digital assets are stewarded by an identifiable organization: a foundation that funds development and holds a treasury, a company that employs the core team, or both. Stewardship has real benefits, including faster shipping, coordinated upgrades, and someone to answer regulators. It also creates exactly what Bitcoin was designed to eliminate: a point of control. An organization can be pressured, sued, acquired, or simply change its mind, and the protocol follows. The deliberateness of Bitcoin's development process is a frequent target of criticism from faster-moving projects, and the criticism mistakes the design for a defect. Changes to a monetary network holding trillions of dollars in value carry risks that move-fast engineering cultures are not built to manage. Bitcoin's process demands overwhelming consensus precisely so that the rules its holders rely on cannot drift underneath them. The reasoning is laid out in Why Doesn't Bitcoin Have More Features? ## Narrow Scripting by Design Bitcoin transactions are governed by [Bitcoin Script](https://help.blockstream.com/education/glossary/bitcoin-script), a deliberately constrained language that supports signatures, timelocks, multisignature arrangements, and similar spending conditions, while excluding loops and unbounded computation. Smart-contract platforms take the opposite approach: a general-purpose virtual machine on which developers can deploy arbitrary programs. The trade-off has real costs on both sides. General-purpose programmability enables applications that Bitcoin's base layer cannot host: automated lending markets, programmable tokens, on-chain exchanges. The price is a larger attack surface, since every expressive contract is a potential exploit, and a heavier validation burden that tends to push nodes toward professional operators. Bitcoin's narrowness keeps every transaction cheap to verify on modest hardware, keeps the base layer's behavior predictable, and confines complexity to where it can fail safely. Bitcoin's answer to programmability is layered architecture rather than base-layer expansion. Payment channels on the Lightning Network deliver instant payments, and sidechains such as the Liquid Network add asset issuance and stronger scripting, in each case without loading risk onto the consensus layer that secures the money itself. The design philosophy is covered in Why Does Bitcoin Use Layers? ## Why the Distinction Matters The structural differences carry practical consequences that show up far from protocol design. **Regulatory treatment.** U.S. regulators have treated bitcoin as a commodity since 2015, when the CFTC first classified it as one. That gives bitcoin the longest-settled commodity treatment of any digital asset, across a decade of enforcement, and the earliest spot exchange-traded products. Many other assets have faced securities analysis for a reason rooted in this article's subject: where an identifiable team raised money from the public and works to increase a token's value, securities law has questions it does not have for a network with no issuer. **Institutional behavior.** Corporate treasuries, ETF issuers, and sovereign-scale holders have overwhelmingly concentrated on bitcoin rather than the broader market, because the properties institutions need (predictable supply, no controlling counterparty, the deepest liquidity) are the properties this article describes. **The vocabulary itself.** The umbrella word "crypto" folds bitcoin into a category dominated by assets with issuers, treasuries, and roadmaps. Blockstream's editorial practice, reflected across this education hub, is to say Bitcoin when meaning Bitcoin. Precision in language follows from precision in the underlying facts: an asset with no issuer behaves differently from assets with one, and a reader evaluating any digital asset can start by asking which of the five properties above it actually has.

Bitcoin is a monetary network with a fixed 21 million supply, proof-of-work security, and no controlling organization. Ethereum is a general-purpose smart-contract platform whose monetary policy has changed several times and which moved to proof-of-stake in 2022\. They pursue different goals with different designs and trust models. ### Are all cryptocurrencies decentralized like Bitcoin? No. Decentralization varies enormously. Most digital assets have an identifiable founding team, a foundation holding a treasury, or a token distribution concentrated among early insiders, any of which creates a point of control. Bitcoin's creator is absent, its launch allocated nothing to insiders, and rule changes require broad voluntary consensus. ### Why doesn't Bitcoin have smart contracts like other blockchains? Bitcoin includes a scripting language, but it is deliberately narrow. Restricting what scripts can do keeps every transaction cheap to verify, keeps the attack surface small, and protects the monetary base layer. More expressive functionality is built on layers above the protocol, such as Lightning and sidechains, rather than into consensus. ### Is Bitcoin safer than other cryptocurrencies? Bitcoin has the longest operating history, the most accumulated proof-of-work, and the most widely reviewed codebase in the industry, which makes its settlement assurances the strongest available. Safety for a holder still depends on custody: a compromised exchange account or lost recovery phrase loses bitcoin as surely as any other asset. ### Is bitcoin a cryptocurrency? Bitcoin fits the dictionary definition, and regulators group it that way, but the label hides more than it reveals. U.S. regulators classify bitcoin as a commodity, while many other digital assets have faced securities analysis because an identifiable team raised funds and steers the project. The economic and legal differences are categorical.
