Bitcoin is the first and most well-known digital currency in the world. It allows people to send money directly to each other, without needing banks, governments, or middlemen.
Created in 2009 by Satoshi Nakamoto, Bitcoin uses a public ledger called the blockchain to record every transaction. This system keeps the network open, transparent, and nearly impossible to alter.
Today, Bitcoin is more than just online money. It’s a global financial network that challenges how traditional money works. From saving and investing to payments and remittances, Bitcoin gives users full control over their funds, anytime, anywhere.

Understanding Bitcoin
What Is Bitcoin?
Bitcoin is a digital currency that operates on a peer-to-peer network. This means users can send or receive coins directly, without going through a bank. Each transaction is verified by thousands of computers (called nodes) that maintain the same copy of the ledger, known as the blockchain.
Bitcoin is limited to 21 million coins, which keeps it scarce, similar to gold. People can store Bitcoin in digital wallets and use it for payments, trading, or as an investment.
Why Bitcoin Matters
Bitcoin represents a new kind of money, open, borderless, and transparent. It allows anyone with internet access to move value globally in minutes. For many, it offers a financial alternative when banks are slow, expensive, or unavailable.
How Bitcoin Works
We should look into the mining process and the wallet to understand how Bitcoin works.
Bitcoin Mining
Bitcoin relies on a consensus known as proof-of-work (PoW), where network contributors are known as “miners.” Miners receive newly-mined Bitcoin whenever they add new blocks to the network.
Bitcoin has a capped total supply of 21 million coins. Once miners mine all these coins, the network will stop minting new ones.
The Bitcoin network goes through a halving process that reduces the amount of Bitcoin miners receive over time. Lowering the Bitcoin supply will support the price of BTC based on the forces of supply and demand.
The most recent halving process happened on April 20, 2024. After this event, half of the miner rewards were slashed from 6.25 BTC to 3.125 BTC. The next event will occur after four years or after the Bitcoin network processes another 210,000 blocks.
Bitcoin price gains have historically followed the halving event. As demand grows against a reducing supply, investor sentiment turns bullish, with BTC recording fresh all-time highs shortly after.
Bitcoin wallets and Keys
The Bitcoin wallet secures cryptographic keys, a special type of password. These keys prove the ownership of a given amount of Bitcoin on the blockchain. It would be best if you kept your private keys safe. You should also note down your keyphrase (password) in a place where you can retrieve it quickly to avoid losing your Bitcoin.
Executing Bitcoin transactions involves two types of keys: a private key and a public key. The keys contain random alphanumeric characters to encrypt and decrypt transactions on the network.
The public-key cryptography (PKC) conserves the authenticity of the Bitcoin blockchain through unassailable transactions. PKC also grants exclusivity to those with the correct number of keys, granting ingress to specific coins.
The Benefits of Bitcoin
Financial Independence
Bitcoin allows users to control their own money without relying on banks or governments. With just a mobile phone and internet connection, anyone can send or receive value worldwide, anytime, without permission or restrictions.
Transparency and Security
Every transaction is recorded on the blockchain, which anyone can view. This open record keeps Bitcoin secure, making it nearly impossible to fake or alter a transaction. Cryptography protects users, while decentralisation removes single points of failure.
Inflation Protection
Unlike traditional currencies that can be printed endlessly, Bitcoin’s supply is fixed at 21 million coins. This scarcity helps it act as a hedge against inflation, especially in countries where local money loses value quickly.
Global Accessibility
Bitcoin works the same in every country. Whether someone lives in New York, Lagos, or Manila, they can use Bitcoin for payments, savings, or remittances, without exchange barriers or banking delays.
Investment and Innovation
Bitcoin has inspired thousands of new projects in blockchain technology, finance, and digital identity. It remains the foundation of the crypto ecosystem, driving both innovation and investor confidence worldwide.
How to Acquire and Store Bitcoin
If you want to acquire Bitcoin, you can do so through a cryptocurrency exchange. With these platforms, users can hold, buy and sell Bitcoin.
Cryptocurrency exchanges have a similar operational mechanism to that of traditional brokerage platforms. Regulators mandate these platforms to verify user identities and deposit fiat that is later traded for Bitcoin or other cryptocurrencies.
Selecting a cryptocurrency exchange depends on security, a friendly user interface, and market influence.
How to Buy Bitcoin on a Cryptocurrency Exchange
If you want to buy Bitcoin through a cryptocurrency exchange, the first thing to do is to create an account. The account creation process is easy for most exchanges, as you only need an email address and phone number.
However, to transact on an exchange, you must submit documents verifying your identity, such as a government-issued ID, driver’s license, passport, etc. You will also be prompted to create a strong password for your account. Some exchanges allow you to secure your account using biometrics for enhanced security.
Once you open an account, the next step is to fund the account. You can do that using your credit card. Link your credit card to your account and deposit the money you want to use to buy Bitcoin.
After depositing funds, go to the trading page on your exchange account or search “Bitcoin” on the exchange’s search bar, and you will get an option to buy. Create a buy order, and once it is fulfilled, you will see the Bitcoin you purchased in your account.
How to Store Bitcoin
You can store Bitcoin in a cryptocurrency wallet, either a hot or cold wallet. In the case of a hot wallet, the exchange or cloud provider will store your Bitcoin online for easy retrieval.
Cold wallets come in handy for long-term secure storage. You can also choose a hardware wallet if you are not planning to sell your Bitcoin in the near term. The most popular hardware wallets are Ledger and Trezor.
Once you store your Bitcoin in a wallet, preserve the integrity of your password. You should complete regular upgrades to patch any bugs. You should also adopt safe internet practices to avoid your Bitcoin falling into the wrong hands. Hackers are always looking for loopholes to access Bitcoin, either through phishing campaigns or malware.
The Role Of Bitcoin In The Financial Landscape
Bitcoin has a scarce supply, as only 21 million coins can ever exist. Its capped supply and increasing demand make it “digital gold.”
Bitcoin proponents claim it is a better alternative to fiat currency, which often depreciates. Bitcoin’s demand will grow with time as supply remains constant, which positions it as a store of value and a hedge against inflation.
Bitcoin transactions do not need a central authority. This feature makes Bitcoin ideal for cross-border transactions. It also makes the coin accessible to unbanked populations who do not own bank accounts.
Besides being used as a currency, Bitcoin is quickly gaining usage as an investment product. The asset can be traded in the same way as other traditional financial assets, including stocks.
While Bitcoin can be used as a source of investment, it often ranks as a high-risk asset. The price can change quickly, making it more volatile than other investment products like stocks.
Moreover, Bitcoin’s use case as an investment remains highly unregulated. Countries such as China have banned Bitcoin because of its speculative nature. Recently, reports circulated on the possibility of Russia also banning Bitcoin.
Despite these bouts of lack of confidence in Bitcoin, its use case as an investment class has continued to grow. Its ability to deliver quick returns within a short period has also made it a popular asset class for investors with a high-risk appetite.
The Integration of Bitcoin into Traditional Finance
Bitcoin has slowly been finding its way into the traditional finance industry for over a decade. For instance, BlackRock, the world’s largest asset manager with more than $10 trillion in assets under management, is paving the way for BTC’s relevance in the traditional financial system.
In January 2024, BlackRock launched spot Bitcoin exchange-traded funds (ETFs) that have amassed billions of dollars in inflows since their launch. Data from its website shows that the giant asset manager holds more than 274,000 BTC, which is worth over $17 billion.
The other major Wall Street players offering Bitcoin products to their clients include Fidelity.
The launch of spot Bitcoin ETFs after approval by the US Securities and Exchange Commission (SEC) marked a significant endorsement for Bitcoin. It also marked a shift in the regulatory framework as the asset was previously associated with criminal activities.
Risks and Challenges of Bitcoin
Market Volatility
Bitcoin’s price can move sharply in a short time. This volatility attracts traders but worries long-term investors. Prices are influenced by news, regulation, and large market players. Managing risk through research and patience is key.
Security and Theft Risks
While the blockchain itself is secure, users can still lose funds through phishing scams, fake exchanges, or lost private keys. Once Bitcoin is stolen, it’s nearly impossible to recover. Using hardware wallets and two-factor authentication offers stronger protection.
Regulatory Uncertainty
Governments continue to debate how to regulate cryptocurrencies. Some countries support innovation, while others limit use or impose taxes. Regulations affect price, accessibility, and how easily businesses can accept Bitcoin.
Environmental Concerns
Bitcoin mining uses high computing power and energy. Although renewable energy use is growing, the network’s carbon footprint still draws criticism. Newer technologies and green mining initiatives aim to make Bitcoin cleaner and more efficient.
Knowledge Gap
Many new users still struggle to understand how Bitcoin works. Without proper education, people fall for scams or lose access to their wallets. The best defence is learning before investing and using only verified platforms.
The CEO of JPMorgan, Jamie Dimon, believes that Bitcoin’s continued use in illegal activities makes it a fraud and a Ponzi scheme. Nevertheless, he acknowledges the potential of blockchain technology and its impact on finance.
Impact of Bitcoin on Society
Bitcoin is challenging the traditional ethos of finance. It gives people sway in their financial lives through autonomy and decentralisation. Bitcoin is also more unassailable than fiat because of blockchain technology.
Bitcoin has played a significant role in helping the unbanked become part of the financial system by enabling cross-border payments. With Bitcoin, people do not need to have a bank account. Instead, they can own a crypto wallet and start transacting in Bitcoin.
Traditional banking systems are making progress with digitisation. However, they still lag behind Bitcoin. Bitcoin’s superiority over fiat is evident because of improved efficiency and cross-border transactions.
Blockchain technology also powers smart contracts and decentralised applications. It is behind innovative solutions like decentralised finance (DeFi), non-fungible tokens (NFTs), and Web3 games.
With the increased adoption of blockchain technology across multiple industries and the steady integration of Bitcoin into traditional finance, it is easy to see that digital currencies will shape the future of finance.
Final Thoughts
Bitcoin started as a small idea in 2009 but has grown into a global movement. It changed how people think about money, giving control back to users, not banks. Through the blockchain, it proved that a secure and transparent financial system can run without middlemen.
In 2025, Bitcoin stands as both an investment asset and a technology platform shaping new forms of trust. It carries risks, from price swings to regulation, yet its long-term promise remains clear: open access to money for everyone, everywhere.
