Bitcoin (BTC) was the first of its kind to be built on blockchain technology. Bitcoin was created to provide a decentralised electronic cash system that operates without the intervention of a centralised authority.

Bitcoin is a groundbreaking digital currency first introduced in 2008 by an anonymous individual or group under the pseudonym Satoshi Nakamoto. Unlike traditional currencies, Bitcoin operates without the need for central banks or governments. It functions as a decentralised system, where all transactions are recorded on a public digital ledger called the blockchain. This decentralisation ensures that no single entity controls the currency or its usage.
Users of the Bitcoin protocol collectively manage the system, following predefined rules encoded in software. These rules govern the total supply of Bitcoin, its creation, and how users trade it.
Bitcoin operates through its global network without government control. Its decentralised nature allows transactions to occur between wallets, verified by miners who secure the network through a consensus process. This decentralised agreement system ensures that users cannot manipulate or double-spend Bitcoin.
At the core of Bitcoin’s security are two key technologies: public-key cryptography and peer-to-peer networking. Wallet software assigns each Bitcoin owner a public key (used to verify ownership) and a private key (a password that secures access to their Bitcoin). Miners compete to add new blocks of transactions to the blockchain, ensuring the system remains decentralised and secure.
Bitcoin can be bought, sold, and traded on most cryptocurrency exchanges. New Bitcoin is generated through a process called mining, where powerful computers solve complex mathematical problems to maintain the network and validate transactions. The network then records these transactions on the blockchain ledger.
Miners are rewarded for maintaining the network by receiving newly minted Bitcoin through a process called mining. Bitcoin's supply is controlled through a halving mechanism that reduces block rewards over time, eventually capping the total supply at 21 million coins.
Satoshi Nakamoto is the pseudonym of the unknown individual or group who created Bitcoin and its blockchain technology.
Despite Bitcoin's widespread use and significant impact, the true identity of Satoshi Nakamoto remains unknown. Numerous individuals have claimed to be Nakamoto, but none have provided conclusive proof to verify their claims.
Nakamoto went to great lengths to remain anonymous, adding to the intrigue and mystique surrounding Bitcoin's origins. The first Bitcoin transaction, known as the Genesis Block, was mined on the 3rd of January 2009.
Prominent figures in the cryptography community from around the time of Bitcoin's creation, such as Nick Szabo and the late Hal Finney, are often speculated to be Nakamoto. Bitcoin's first real-world transaction occurred on the 22nd of May 2010, when developer Laszlo Hanyecz used 40,000 bitcoins to purchase two pizzas—a moment now celebrated as Bitcoin Pizza Day.
Nakamoto began working on Bitcoin's code as early as 2007, with the white paper outlining the system published in 2008. The first software version, Bitcoin 0.1, was released on the 9th of January 2009.
Before stepping away from the project in 2011, Nakamoto left behind a series of emails and forum posts discussing Bitcoin’s future. Today, the Bitcoin network benefits from the contributions of hundreds of developers who continuously enhance the system through bug fixes and efficiency improvements.
Bitcoin is built upon decades of cryptographic innovations aimed at creating digital money. These foundational projects include:
A proposed system for anonymous, distributed digital cash.
An effort to establish a type of scarce online commodity.
The pioneering attempt at creating anonymous online payments.
A proof-of-work system designed to prevent email spam.
Another distinctive feature of Bitcoin is its capped supply. Unlike fiat currencies, which can be printed at will by central authorities, Bitcoin has a fixed maximum supply of 21 million coins. This scarcity is designed to enhance Bitcoin's value over time, contrasting with fiat currencies that can suffer from inflation and devaluation as more money is issued.
Bitcoin transactions are recorded on a public ledger known as the blockchain, which ensures transparency. Anyone can view and track transactions on this open ledger, adding an extra layer of security and accountability.
In contrast, traditional currencies often lack such transparency, making it easier to conceal transactions and engage in illegal activities like money laundering. Bitcoin's public ledger makes all transactions visible and traceable.
Bitcoin transactions generally incur lower fees compared to traditional banking methods. This makes Bitcoin a more cost-effective option for international payments or transfers. Additionally, Bitcoin transactions are processed much faster, typically within an hour, compared to the 2-5 business days often required for international bank transfers.
Bitcoin transactions are safeguarded by advanced cryptographic techniques, making them highly secure and resistant to hacking. Furthermore, Bitcoin transactions are pseudonymous, allowing users to conduct transactions without disclosing their personal identities. This feature enhances privacy and security.
The decentralised nature of Bitcoin means it cannot be shut down or banned by any single entity. Its features—decentralisation, limited supply, transparency, lower fees, and strong security—make Bitcoin an appealing option for many users. As digital financial solutions continue to evolve, Bitcoin is well-positioned to play a significant role in the future of finance.
Bitcoin has several practical applications:
Users can transfer funds without needing third-party intermediaries like banks or payment processors. The decentralised network can complete transactions faster and more cheaply compared to traditional payment methods.
Due to its limited supply and decentralisation, many view Bitcoin as a stable and secure currency. Some people invest in Bitcoin, hoping its value will appreciate over time, though its price can be volatile.

High Volatility and Risk of Loss:
Investing in crypto assets involves significant risk, and may result in the loss of capital. Cryptocurrency markets are highly volatile and may experience sudden and substantial fluctuations in value. As such, there is a possibility that you may receive an amount less than your original investment or experience a complete loss of your initial investment's value.
Remember past performance doesn’t guarantee future results and we can’t guarantee returns since asset prices move based on supply and demand, so never trade with funds you can’t afford to lose.
Altify does not provide investment advice or recommendations. As an investor, you are responsible to make decisions regarding your investments. You should seek professional advice if you're uncertain about the suitability or appropriateness of any investment for your specific circumstances or needs.
Lack of Regulation and Protections:
While the cryptocurrency industry is gradually becoming more regulated, it remains largely unregulated. As a result, your holdings are not protected by any government-backed insurance scheme or financial services compensation scheme. In the event of a loss, theft, or cyber attack, there is no guarantee that you will be able to recover your funds.
Irreversibility of Transactions:
Crypto transactions are irreversible. Sending funds to an incorrect address or falling victim to fraudulent activities may result in the permanent loss of your assets. Ensure all transaction details are correct before proceeding.
Market Liquidity and Accessibility:
Under certain market conditions, it may be difficult or impossible to liquidate a position quickly at a reasonable price. The value of your crypto assets is driven by market demand, which can fluctuate and potentially result in a total loss of value.
Tax and Legal Considerations:
Investing in cryptocurrencies may result in tax liabilities. It is your responsibility to understand and comply with your local tax laws and regulations. Cryptocurrencies may also be subject to changes in legislation that could affect their use, value, and legality.
