Bitcoin Fundamentals: Structure, Scarcity and Use |
Understanding the first and most established cryptocurrency
What is Bitcoin?
Bitcoin is a cryptocurrency designed to enable peer-to-peer transfers of value without reliance on centralized intermediaries such as banks or governments. Introduced in 2009, Bitcoin was the first application of blockchain technology and remains the most widely recognized cryptocurrency.1 Bitcoin exists on its own blockchain, a shared network that records and verifies transactions.1
How the Bitcoin Network Works
The Bitcoin blockchain functions as a decentralized ledger that records every transaction in chronological order. Transactions are grouped into “blocks,” validated by the network and added to the blockchain at regular intervals.
Key Features of the Bitcoin Network
Bitcoin and Digital Scarcity
A defining characteristic of Bitcoin is its fixed supply. The Bitcoin protocol limits total issuance to 21 million coins, a feature embedded in the network’s code. New Bitcoin is introduced at a predetermined pace that slows over time through a process known as block reward halving.2
Approximately 20 million Bitcoin—roughly 95% of the total eventual supply—have already been created as of early 2026.3 The remaining supply is scheduled to be issued gradually over the coming decades. This programmed scarcity has contributed to frequent comparisons between Bitcoin and scarce physical assets such as gold.
Bitcoin as an Asset
Bitcoin is commonly described as a digital commodity rather than a traditional currency. Market participants and regulators generally view it as a store of value or investment asset rather than as legal tender.4
Within financial markets, Bitcoin has exhibited significant price volatility, sensitivity to macroeconomic and regulatory developments and periods of low correlation with traditional asset classes. These characteristics have shaped how investors evaluate Bitcoin within broader portfolio discussions.4
Bitcoin at a Glance
| ATTRIBUTE | BITCOIN |
| Launch | 2009 |
| Primary role | Store of value / value transfer |
| Supply structure | Fixed (21 million maximum) |
| Network design | Decentralized, peer-to-peer |
| Transaction validation | Proof of work |
| Block creation | Approximately every 10 minutes |
Portfolio Applications
Some investors consider Bitcoin appropriate for a modest portfolio allocation, depending on their specific circumstances. Interest has increased alongside regulatory tailwinds in several jurisdictions, growing global adoption and continued development of market infrastructure such as custody, trading and settlement.
From an investment perspective, Bitcoin is often viewed as a potential source of capital appreciation, reflecting its fixed supply, increasing adoption and sensitivity to changes in investor demand. Its programmed scarcity and expanding participation have historically contributed to periods of significant price appreciation, though with substantial volatility. Bitcoin has also exhibited periods of low or variable correlation with traditional asset classes, leading some investors to evaluate its role as a potential portfolio diversifier.5
At the same time, Bitcoin remains volatile and subject to evolving regulatory, technological and market dynamics. It may not be suitable for all investors, and any role depends on individual objectives, risk tolerance, liquidity needs and time horizon.
| Key Takeaway | Bitcoin represents the earliest and most established application of blockchain technology. Its decentralized structure, fixed supply and independent network distinguish it from both traditional currencies and other digital assets. Understanding these foundational characteristics can help investors more thoughtfully assess Bitcoin’s potential role within an evolving financial landscape. |
