FUNDAMENTALS OF CRYPTO
What is Bitcoin?
The Original Cryptocurrency
Every movement starts with a spark. For crypto, that spark was Bitcoin. In 2008, during the peak of the global financial crisis, an anonymous figure or group using the name Satoshi Nakamoto published a nine-page document titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” The idea was simple but revolutionary: create a digital currency that allows people to send money directly to each other without going through a bank, government, or payment processor. What followed was not just the creation of a new form of money. It was the birth of an entirely new industry, a new philosophy about value and ownership, and a technological breakthrough that continues to reshape how the world thinks about finance, trust, and sovereignty over one’s own wealth. This guide explains what Bitcoin is, how it works, why it was created, and why it remains the foundation of everything built in the crypto ecosystem today.
🤝 Decentralisation: No central authority could control or issue Bitcoin. The network runs on thousands of independent nodes worldwide.
🔒 Fixed Supply: Only 21 million Bitcoins will ever exist, protecting it from inflation.
📑 Transparency and Security: Every transaction is publicly recorded, but identities remain pseudonymous.
🧩 Proof of Work: Transactions are verified and added to the blockchain by miners solving complex mathematical puzzles. This process ensures the network’s security.
The Problem Bitcoin Was Designed to Solve
To understand why Bitcoin matters, you first need to understand the problem it was created to solve. For decades before Bitcoin existed, the concept of digital money had been technically possible in theory but practically impossible without a centralised intermediary. The reason came down to what computer scientists called the double-spend problem.
Physical cash solves the double-spend problem naturally. If you hand someone a AUD $50 note, you no longer have it. The transfer is final and self-evident. Digital files, however, can be copied infinitely at zero cost. If you sent someone a digital token representing $50, what was to stop you from sending the same token to someone else simultaneously, or keeping a copy for yourself? Nothing, unless a trusted third party, a bank, a payment processor, or some other intermediary, was responsible for maintaining a ledger of who owned what and ensuring the same unit of value was not spent twice.
This is why every form of digital payment that existed before Bitcoin required trust in a centralised authority. When you pay with a credit card, you trust Visa or Mastercard to verify the transaction. When you transfer money via a bank, you trust the bank to deduct it from your account and credit it to the recipient’s. The entire global financial system was built on this model: centralised ledgers maintained by institutions whose integrity you trusted, or were compelled to trust, because there was no alternative.
The 2008 global financial crisis exposed the fragility of that trust in the most dramatic possible way. Banks that had been considered too large and too sophisticated to fail revealed themselves to be operating on foundations of extraordinary fragility and mismanagement. Governments responded by using taxpayer money to bail out the very institutions whose recklessness had caused the crisis. Ordinary people absorbed the losses while the institutions responsible were rescued. Satoshi Nakamoto watched all of this and embedded a message in the very first block of the Bitcoin blockchain, known as the genesis block: a newspaper headline reading “Chancellor on brink of second bailout for banks.” The message was a declaration of intent. Bitcoin was not simply an experiment in digital payments. It was a direct response to a financial system that had demonstrated its inability to be trusted with the money of ordinary people.
The Whitepaper: Nine Pages That Changed Everything
On the 31st of October 2008, Satoshi Nakamoto published the Bitcoin whitepaper to a cryptography mailing list. At nine pages, it is one of the most consequential documents in the history of technology and finance. The paper described a solution to the double-spend problem that required no trusted third party whatsoever.
Satoshi’s solution was the blockchain: a distributed ledger that records every Bitcoin transaction ever made in a chain of blocks, each one cryptographically linked to the one before it. Rather than maintaining the ledger on a single server owned by a single company, the blockchain would be maintained simultaneously by thousands of independent computers around the world, each holding a complete copy of the entire transaction history.
The genius of this design was its resistance to manipulation. To alter any transaction in the blockchain, an attacker would need to alter every subsequent block in the chain simultaneously, and do so faster than the rest of the network was adding new blocks. On a network of thousands of independent nodes, this is computationally infeasible. The transaction history is effectively immutable: once a transaction is confirmed and buried under enough subsequent blocks, it is permanent and irreversible.
To verify and add new transactions to the blockchain, Satoshi designed a competitive process called proof of work. Participants called miners compete to solve complex cryptographic puzzles using computational power. The first miner to solve the puzzle is permitted to add the next block of transactions to the chain and is rewarded with a specific number of newly created Bitcoin. This reward system serves two purposes: it incentivises miners to participate honestly, and it is the mechanism through which new Bitcoin enters circulation.
What made this an understanding-worthy crypto whitepaper was that it solved a decades-old computer science problem in a way that was simultaneously technically elegant, economically incentivised, and practically implementable. The blockchain consensus mechanism Satoshi described became the template for an entirely new category of technology.
Bitcoin's Core Design Principles
Bitcoin was not designed by accident. Every aspect of its architecture reflects deliberate choices made to serve specific goals. Understanding those design principles explains why Bitcoin behaves the way it does and why its properties make it uniquely suited to its role as a foundational monetary asset.
Decentralisation
No central authority controls or issues Bitcoin. The network runs on thousands of independent nodes worldwide, each holding a complete copy of the blockchain and validating transactions according to the same set of rules encoded in the Bitcoin protocol. No government, company, or individual can unilaterally change those rules, freeze accounts, reverse transactions, or create new Bitcoin outside the protocol’s defined issuance schedule. The network has no headquarters, no CEO, and no single point of failure.
This decentralisation is Bitcoin’s most fundamental property and the one that most directly addresses the trust problem that motivated its creation. You do not need to trust any institution when using Bitcoin. You need only trust the mathematics underlying the protocol, which you can verify independently. This is why the phrase “don’t trust, verify” is so central to Bitcoin’s culture and philosophy.
Fixed Supply
Only 21 million Bitcoin will ever exist. This is not a policy that can be changed by a vote or a decree. It is hardcoded into the Bitcoin protocol, and changing it would require the agreement of the vast majority of the network’s participants, who have every incentive to preserve the scarcity that underpins Bitcoin’s value. As of 2024, approximately 19.7 million Bitcoin have already been mined. The remaining supply will be issued gradually through the mining reward process over the coming century, with the last Bitcoin expected to be mined around the year 2140.
This fixed supply is the foundation of Bitcoin’s monetary properties. Unlike every fiat currency in history, which has been subject to inflationary expansion by the issuing authority, Bitcoin cannot be inflated. No central bank can decide to print more of it. No government can debase it to finance spending. The purchasing power of each unit is protected by mathematical scarcity in a way that no human-governed monetary system has ever achieved. This is the core of the Bitcoin as digital gold thesis that has attracted investors seeking a hedge against monetary debasement.
Transparency and Pseudonymity
Every Bitcoin transaction ever made is recorded publicly on the blockchain and is permanently visible to anyone who wants to look. You can examine the full transaction history of any Bitcoin address using a blockchain explorer, seeing exactly how much Bitcoin moved, when, and between which addresses.
At the same time, those addresses are not inherently linked to real-world identities. Bitcoin is pseudonymous rather than anonymous: transactions are publicly visible but the people behind the addresses are not automatically identifiable. This balance between transparency and pseudonymity makes Bitcoin uniquely auditable: the supply can be verified precisely, no hidden creation of Bitcoin is possible, and the integrity of the ledger can be checked by anyone at any time.
Proof of Work
The mechanism by which Bitcoin transactions are verified and added to the blockchain is called proof of work, which is Bitcoin’s consensus mechanism. Miners compete to solve a cryptographic puzzle whose difficulty automatically adjusts every two weeks to ensure that a new block is added approximately every 10 minutes regardless of how much total mining power is on the network. The winner adds the block and receives the block reward.
Proof of work requires the expenditure of real-world energy and computational resources to participate in network security. This energy cost is not a flaw. It is the mechanism that makes attacking the network prohibitively expensive. To rewrite the Bitcoin blockchain, an attacker would need to expend more computational power than the entire rest of the network combined, an investment that would cost billions of dollars and whose only reward would be the destruction of the asset whose value makes the attack worthwhile in the first place. The economic incentives make honest participation overwhelmingly more rational than dishonest attack.
The Bitcoin Halving and Its Economic Significance
Built into Bitcoin’s protocol is one of its most important and most discussed features: the Bitcoin halving. Approximately every four years, or precisely every 210,000 blocks, the reward paid to miners for adding a new block to the blockchain is reduced by 50 percent.
When Bitcoin launched in January 2009, the block reward was 50 BTC. In 2012 it halved to 25 BTC. In 2016 it halved again to 12.5 BTC. In 2020 it dropped to 6.25 BTC. The April 2024 halving reduced it to 3.125 BTC. This process will continue until all 21 million Bitcoin have been issued, with the block reward approaching zero asymptotically over the next century.
The halving has profound economic implications. It reduces the rate at which new Bitcoin enters circulation by half overnight, creating a structural supply shock that has historically been a major driver of Bitcoin’s price cycles. If demand remains constant or grows while new supply is suddenly cut in half, basic economics dictates that price must rise to establish a new equilibrium. Each of Bitcoin’s four halvings to date has preceded a period of significant price appreciation, a pattern that has become the basis for the four year Bitcoin halving cycle that many investors and analysts use as a macro framework for understanding Bitcoin’s market behaviour.
The halving also directly affects Bitcoin’s tokenomics and its stock-to-flow ratio, which measures the existing supply of an asset relative to its annual new production. After the 2024 halving, Bitcoin’s stock-to-flow ratio exceeded that of gold for the first time in history, meaning Bitcoin is now scarcer in flow terms than the metal that has served as humanity’s primary monetary store of value for millennia.
How Bitcoin Transactions Actually Work
When you send Bitcoin to another person, what actually happens? Understanding the mechanics of a Bitcoin transaction demystifies the technology and helps you appreciate both its elegance and its implications.
Every Bitcoin user has a wallet that contains one or more pairs of cryptographic keys: a public key, which functions like a bank account number and can be shared freely with anyone who wants to send you Bitcoin, and a private key, which functions like a PIN and must never be shared with anyone because it is the only proof of ownership of the Bitcoin associated with that address.
When you send Bitcoin, you broadcast a transaction to the network stating that you are transferring a specific amount from your address to the recipient’s address. This transaction is signed with your private key, providing cryptographic proof that you authorised the transfer. Nodes on the network verify that the signature is valid and that the address you are sending from actually holds the Bitcoin you are claiming to send. Valid transactions are broadcast across the network and collected by miners into a pool of pending transactions.
Miners select transactions from this pool, typically prioritising those with higher gas fees attached, and include them in the block they are competing to add to the blockchain. Once your transaction is included in a confirmed block, it is part of the permanent, immutable record. After a few additional blocks are added on top of it, the transaction is considered irreversible. The full journey from broadcast to irreversible confirmation typically takes between 10 minutes and an hour depending on network congestion and the fee you attached.
This process, fully described in our guide on how cryptocurrency transactions work, eliminates every intermediary that traditional payments require. No bank approves your transaction. No payment processor validates your identity. No government can block or reverse the transfer. The mathematics of cryptography and the distributed consensus of the network are the only authorities involved.
Bitcoin as a Store of Value: Digital Gold
Bitcoin began its life as an experiment in peer-to-peer electronic cash, and for its first few years it was used primarily as a medium of exchange within niche online communities. The famous story of the first commercial Bitcoin transaction, 10,000 BTC exchanged for two pizzas in 2010, illustrates both how far Bitcoin has come and how the market’s understanding of its primary use case has evolved.
Over time, as Bitcoin’s price appreciation became evident and its monetary properties became more widely understood, the dominant narrative shifted. Most people do not use Bitcoin primarily to buy things day to day. They hold it as a store of value, a long-term savings vehicle that protects purchasing power over time in a way that government-issued currencies, subject to continuous inflation, cannot.
The comparison to gold is instructive. Gold has served as a store of value for thousands of years because of its scarcity, its durability, its fungibility, and its resistance to the control of any single authority. Bitcoin shares all of these properties in digital form, and in some respects improves upon them. Bitcoin is more portable than gold: transferring billions of dollars worth of Bitcoin across the world takes minutes and costs a few dollars. Bitcoin is more divisible than gold: it can be divided into units as small as one hundred-millionth of a Bitcoin, called a satoshi. Bitcoin is more verifiable than gold: its supply can be audited precisely by anyone at any time using publicly available blockchain data, while verifying the authenticity of physical gold requires specialist equipment and expertise.
These properties have attracted an increasingly diverse range of investors and institutions to Bitcoin as a portfolio asset. From individual retail investors in Australia seeking exposure to a non-correlated asset, to publicly listed companies holding Bitcoin as a treasury reserve, to sovereign wealth funds and national governments exploring Bitcoin as a reserve asset, the recognition of Bitcoin’s monetary properties has expanded dramatically across every cycle. The comparison of Bitcoin against other asset classes provides further context for how it fits within a diversified investment portfolio.
Bitcoin and the Ecosystem It Created
Bitcoin’s most profound contribution to the world extends beyond its own monetary properties. By proving that a decentralised, trustless digital ledger was technically and economically viable, Bitcoin opened the door to an entirely new category of technology and finance.
Ethereum, launched in 2015 by Vitalik Buterin and a team of developers, extended Bitcoin’s foundational concept of a decentralised ledger into a general-purpose programmable platform. Where Bitcoin’s blockchain is designed primarily to record and transfer value, Ethereum’s blockchain can execute smart contracts: self-executing programs that run exactly as coded without any possibility of censorship, downtime, or third-party interference. Smart contracts became the foundation for decentralised finance, NFTs, DAOs, and thousands of other applications.
Solana, altcoins, stablecoins, layer 2 solutions, DeFi protocols, play-to-earn gaming, and the entire infrastructure of Web3 identity all trace their lineage directly back to the breakthrough Satoshi Nakamoto described in those nine pages in 2008. Bitcoin did not just create a new currency. It created a new paradigm for how software, money, and human coordination can interact without requiring trust in centralised authorities.
The difference between coins and tokens that now characterises the crypto ecosystem, the proliferation of crypto ICOs and presales, the emergence of blockchain explorers as tools for auditing and transparency: all of these are downstream consequences of the single foundational breakthrough that Bitcoin represented.
Bitcoin's Role in the Australian Context
For Australians, Bitcoin is increasingly accessible, legally recognised, and taxable. The Australian Taxation Office treats Bitcoin and other cryptocurrencies as property for tax purposes, meaning capital gains tax applies to disposals and ordinary income tax applies to Bitcoin received as income, payment, or mining rewards. Understanding cryptocurrency tax in Australia and the specific ATO crypto rules that apply to Bitcoin holdings is essential for any Australian investor.
Australians can purchase Bitcoin through a range of regulated, AUSTRAC-registered exchanges. Our how to buy Bitcoin in Australia guide covers the step-by-step process in full, including which platforms offer the best combination of fees, security, and ease of use for Australian investors. For those new to crypto more broadly, our guide on how to buy cryptocurrency for the first time provides a complete beginner’s framework.
Once purchased, Bitcoin should be held in a secure cryptocurrency wallet. The choice between hot wallets, software wallets, and cold wallets reflects a trade-off between convenience and security that every Bitcoin holder needs to understand. The principle of not your keys, not your crypto is particularly relevant for Bitcoin, where the consequences of losing access to private keys or seed phrases is permanent and irreversible loss of the associated holdings.
For investors building long-term Bitcoin exposure as part of a broader strategy, approaches like dollar-cost averaging and understanding risk management provide the strategic foundation for participating in Bitcoin’s long-term trajectory without being destroyed by its short-term volatility. The decision of investing in Bitcoin versus altcoins is one of the most fundamental portfolio questions every crypto investor eventually faces, and understanding Bitcoin’s unique properties as the market’s foundational asset is essential context for making that decision well.
Bitcoin's Challenges and Criticisms
No honest account of Bitcoin is complete without acknowledging the genuine criticisms and challenges it faces. Understanding these is as important as understanding Bitcoin’s strengths, because they shape the risks that Bitcoin investors carry and the uncertainties that remain about its long-term trajectory.
Energy Consumption
Bitcoin’s proof of work consensus mechanism requires enormous amounts of electrical energy to operate. The global Bitcoin mining network consumes approximately as much electricity as some medium-sized countries, a fact that attracts significant criticism from environmental advocates. Supporters argue that an increasing proportion of that energy comes from renewable sources, that the energy expenditure is the deliberate security cost of a decentralised monetary network, and that the traditional banking system consumes comparable or greater energy when its full infrastructure is accounted for. This debate is ongoing and its resolution will likely influence Bitcoin’s regulatory treatment in various jurisdictions.
Volatility
Bitcoin’s price volatility is extreme by the standards of traditional asset classes. Drawdowns of 50 to 85 percent from peak to trough have been a recurring feature of every market cycle. For investors with shorter time horizons or lower risk tolerance, this volatility can make Bitcoin unsuitable as a primary store of value in the near term, even if its long-term trajectory has been consistently upward. Understanding market cycles and the psychology of fear and greed helps contextualise this volatility as a feature of the asset’s maturation process rather than evidence of fundamental instability.
Regulatory Risk
Bitcoin operates in a regulatory environment that varies significantly across jurisdictions and continues to evolve. While Australia has a relatively clear and progressively developing regulatory framework for crypto, other major economies have taken more restrictive approaches at various points. The risk that a major jurisdiction introduces regulations that significantly restrict Bitcoin’s use, accessibility, or tax treatment is a genuine risk that investors must account for in their assessment of the asset.
Scalability
Bitcoin’s base layer can process approximately seven transactions per second, which is far below the capacity required for it to function as a global medium of exchange for everyday transactions. The Bitcoin halving and block size debates that have shaped Bitcoin’s development reflect the genuine tension between security, decentralisation, and scalability that is often described as the blockchain trilemma. Solutions including the Lightning Network, a layer 2 payment channel network built on top of Bitcoin, are addressing this limitation, but scaling Bitcoin while preserving its core properties remains an active area of development.

Bitcoin: The Pioneer of the Digital Currency Revolution
Bitcoin was created in 2008 by the pseudonymous Satoshi Nakamoto as a direct response to the failures of the centralised financial system exposed by the global financial crisis. It solved the double-spend problem that had made trustless digital money impossible by inventing the blockchain: a distributed, immutable ledger maintained simultaneously by thousands of independent nodes worldwide. By doing so, it eliminated the need for any trusted third party in financial transactions for the first time in history, replacing institutional trust with mathematical certainty.
Bitcoin’s core design principles, decentralisation, a fixed supply of 21 million coins, transparent pseudonymous transactions, and proof of work consensus, were not accidental. They were deliberate choices that give Bitcoin its unique monetary properties: resistance to inflation, censorship resistance, global accessibility, and the ability to be verified and audited by anyone at any time. These properties underpin the Bitcoin as digital gold thesis that has attracted an increasingly broad range of investors and institutions to hold Bitcoin as a long-term store of value.
The Bitcoin halving, which reduces the block reward by 50 percent every four years, creates a programmatic and predictable supply shock that has historically been a primary driver of Bitcoin’s market cycles. Each halving has preceded a period of significant price appreciation as reduced new supply meets sustained or growing demand. Combined with the broader macro environment shaped by central bank monetary policy, the four year halving cycle provides one of the most useful frameworks available for contextualising Bitcoin’s long-term price behaviour.
Bitcoin’s most enduring contribution is the paradigm it created. By proving that a decentralised, trustless digital ledger was viable, it opened the door to Ethereum, smart contracts, DeFi, NFTs, and the entire ecosystem of blockchain innovation that has followed. Everything built in crypto today traces its lineage back to those nine pages published on the 31st of October 2008. Bitcoin did not just create a new currency. It created a new way of thinking about money, ownership, and trust that continues to reshape the global financial system more than fifteen years after its creation.
What is Bitcoin?
Bitcoin is a form of digital money that exists entirely on the internet, allowing people to send value directly to one another without needing a bank or a central authority. It was created to provide a sovereign alternative to traditional currencies, meaning it is not controlled by any government. By using a shared digital record book called a blockchain, Bitcoin ensures that every transaction is permanent and transparent, making it the first successful system for digital scarcity.
Why does Bitcoin have value?
Bitcoin has value because it is both useful and scarce. Unlike traditional money, which can be printed in unlimited amounts, there will only ever be 21 million Bitcoins. This fixed supply makes it a hard asset, similar to physical gold, and is a key part of understanding market capitalisation in crypto. Its value also comes from its utility: it allows anyone with an internet connection to move large amounts of wealth across borders instantly, securely, and without needing permission from a third party.
Is Bitcoin legal in Australia?
Yes, Bitcoin is completely legal to own and trade in Australia. In 2026, the Australian government treats Bitcoin as a digital asset rather than a foreign currency. Under the latest ASIC frameworks, exchanges operating in Australia must follow strict rules to protect consumers. While it is legal, the government and the ATO monitor transactions to ensure they are used for legitimate purposes and that taxes are paid correctly. For a full breakdown of how Australian law applies to your holdings, see our guide to crypto tax and regulations.
Who controls the Bitcoin network?
No single person, company, or government controls Bitcoin. Instead, it is run by a global network of thousands of independent computers (nodes) that all follow the same set of mathematical rules. This is known as decentralisation. Because control is spread out across the world, it is nearly impossible for any single group to change the rules or shut the network down, ensuring it remains an open system for everyone. This stands in direct contrast to the institutions covered in our centralised finance explained guide.
How is Bitcoin different from the Australian Dollar?
The main difference is who manages the supply and the rules of the money. The Australian Dollar (AUD) is a fiat currency, managed by the Reserve Bank of Australia, which can increase the supply of money to manage the economy. Bitcoin is a digital commodity with a fixed supply that no one can change. While AUD is designed for local stability and everyday spending, Bitcoin is designed to be a global store of value that cannot be devalued by inflation. Our economics and macro category explores this relationship in depth.

What is Bitcoin mining?
Mining is the process that secures the Bitcoin network and brings new coins into circulation. Instead of a bank verifying transactions, miners use powerful computers to solve complex mathematical puzzles. This work proves that transactions are real and prevents anyone from spending the same Bitcoin twice. As a reward for this service, miners receive newly created Bitcoins, which is why the process is called mining: it takes real effort to extract new value from the system.
What is the halving?
The halving is a pre-programmed event that occurs every four years, where the reward given to Bitcoin miners is cut in half. This exists to ensure that Bitcoin remains scarce and that the total supply of 21 million coins is released slowly over time. In 2026, we are navigating the post-2024 halving environment, where the reduced supply of new Bitcoin often acts as a catalyst for increased value as demand grows. Understanding the halving is fundamental to any serious investment strategy in this asset class.
Is Bitcoin safe from hackers?
The Bitcoin network itself is considered one of the most secure computer networks in history. Because it is decentralised, a hacker would need to take control of more than half of all the computers in the world simultaneously to manipulate the ledger, which is practically impossible. However, while the network is safe, your individual holdings are only as safe as your storage method. If you use a secure cold wallet, your Bitcoin is extremely difficult to steal. Our wallets and security category covers exactly how to protect your holdings.
Can I lose my Bitcoin?
Yes, it is possible to lose access to your Bitcoin if you do not manage your security correctly. Because there is no “forgot password” option in the world of decentralised finance, you are responsible for your own private keys, which function as a complex digital password. If you lose these keys or the seed phrase for your wallet, your Bitcoin remains on the blockchain, but you will never be able to move or spend it again. This is one of the most important concepts covered in our wallets and security guides.
Protecting your Bitcoin starts with the right knowledge. Shepley Capital’s Runite membership gives you structured access to our full security and self-custody content, built for everyday Australians who want to hold crypto the right way.
How do I pay tax on Bitcoin in Australia?
In Australia, the ATO views Bitcoin as an asset for Capital Gains Tax (CGT) purposes. This means that if you sell Bitcoin for more than you paid for it, you must pay tax on the profit. In 2026, the ATO has sophisticated systems to track trades made on Australian exchanges. It is vital to keep accurate records of your cost base, meaning the price you paid in AUD, so you can correctly report your gains or losses at the end of the financial year. Our crypto tax and regulations category covers Australian CGT obligations in full detail.
What can I actually buy with Bitcoin?
While Bitcoin is primarily used as a long-term store of value in 2026, its use as a payment method is growing. Many Australian retailers now accept Bitcoin via payment processors, and it is frequently used for high-value international transactions. However, most people choose not to spend their Bitcoin on small daily purchases, preferring to hold it for its potential long-term growth. Our real world adoption category tracks how Bitcoin and other digital assets are being integrated into everyday commerce and institutional finance.
If you are holding Bitcoin as a long-term asset and want to build a structured strategy around it, Shepley Capital’s Black Emerald membership provides deeper market analysis, investment strategy content, and priority access to new research from our team.
Can I buy a fraction of a Bitcoin?
Yes. You do not need to buy a whole Bitcoin, which is a common misconception among new investors. A single Bitcoin can be divided into 100 million smaller units called Satoshis. This means you can start with as little as $10 or $50 AUD at a time. This divisibility makes Bitcoin accessible to everyone regardless of budget, and is one of the reasons the total value locked across the broader crypto ecosystem continues to grow as more everyday Australians enter the market.
