Bitcoin is an innovative payment network that leverages peer-to-peer transactions to remove the need for a central bank. Bitcoin has revolutionized the core principles of value exchange by showing that a network of fully independent nodes can operate payments in a trustless and secure way.
This article explores the basic concepts of Bitcoin and answers some of the common questions people often have when learning about Bitcoin for the first time.

Understanding Bitcoin
Bitcoin, often abbreviated as BTC, is a digital currency. (We use the lower-case bitcoin to refer to the currency and Bitcoin when referring to the network underpinning it.)
Unlike traditional currencies issued by governments, bitcoin exists as a global network of nodes, which are computers whose job is to check the validity of transactions sent by users and record them on a public ledger called blockchain.
The strength of Bitcoin is that anybody with a computer can run a node and take part in the protocol, thus checking that other nodes behave legitimately. This means no single entity controls it — neither governments nor banks nor large corporations.
Registering transactions on the blockchain is an irreversible operation. Nobody can tamper with the historical data to cheat, which makes the Bitcoin protocol very secure.
Is Bitcoin money?
To understand Bitcoin’s role as money, we need to consider its functions:
- Medium of exchange: Bitcoin can be used to buy goods and services from a growing list of merchants and service providers. This includes everything from online retailers to local shops accepting bitcoin as a form of payment.
- Store of value: Many see bitcoin as digital gold, holding value over time and providing a hedge against inflation. Despite its digital nature, creating new bitcoins is a lengthy and expensive process. Together with the fact that the total supply is limited by the protocol, this contributes to bitcoin’s value retention.
- Unit of account: While less common, bitcoin is sometimes used to price goods and services, particularly in digital and tech-savvy markets. This means prices can be denominated in bitcoin instead of traditional currencies.
Who created Bitcoin?
Bitcoin was created by a pseudonymous person (or group of people) known as Satoshi Nakamoto. The concept of Bitcoin draws from earlier work by cryptographers like Wei Dai and the cypherpunks, a group advocating for the use of cryptography to enhance privacy and security in the digital age. Satoshi Nakamoto published the Bitcoin whitepaper in 2008 and launched the Bitcoin network in 2009. Since then, bitcoin’s price and adoption have grown significantly, attracting attention from both individual and institutional investors.
Who controls Bitcoin?
One of the most compelling aspects of Bitcoin is its decentralized nature. Unlike traditional currencies, bitcoin is not controlled by any central authority. Instead, it is based on an open-source protocol maintained and run by a global network of developers and contributors. This decentralized network ensures that Bitcoin remains open, secure, and free from central control.
The heart of the protocol is a consensus mechanism, an algorithm allowing the network of peers to decide on which transactions are valid and can be recorded on the blockchain. The whole process is transparent and verifiable, so that peers are disincentivized from acting maliciously.
Is Bitcoin anonymous?
A common misconception is that Bitcoin is entirely anonymous. In reality, while Bitcoin transactions do not contain personal information, they are recorded on a public ledger for everybody to check and track. This means that while identities are not directly linked to transactions, patterns can potentially be found through blockchain analysis.
For example, it is possible to check each and every transaction associated with a certain Bitcoin address. If that was ever associated with a person (for instance, because it was published online) the whole history of payments would be revealed.
Ongoing developments aim to enhance privacy and security further, with technologies like CoinJoin and the Lightning Network providing additional layers of privacy.
Is Bitcoin secure?
Bitcoin is designed to be secure. The underlying blockchain technology ensures that once a transaction is recorded, it cannot be altered or reversed. This immutability, combined with cryptographic security, makes Bitcoin transactions safe from fraud and manipulation. Additionally, Bitcoin’s decentralized nature reduces the risk of centralized points of failure, enhancing the overall security of the network. Since its creation, no major hacks to the protocol itself have been recorded.
This doesn’t mean Bitcoin is completely immune from any fraud or theft: Like any real-world system, its biggest weakness is individual users. The vast majority of stolen bitcoins can be traced back to poor security practices, from weak passwords to bugs in software used to store bitcoins.
Is Bitcoin legal?
In the vast majority of countries, Bitcoin is legal. However, regulatory environments vary. Some countries have embraced Bitcoin, recognizing it as a legitimate form of currency and investment, while others impose strict controls. For example, countries like the United States and Japan have established clear regulations for Bitcoin, whereas others like China have imposed bans on cryptocurrencies.
In general, Bitcoin transactions and holdings are subject to taxes, much like other financial assets, therefore it is advisable to understand the specific regulations in your Country.
How can you use Bitcoin?
Bitcoin’s uses are diverse and expanding. Major corporations like Wikimedia, Microsoft, AMC, AT&T, and Proton accept bitcoin as a payment method. Additionally, bitcoin is widely used for:
- Investment: Many view bitcoin as a long-term investment, akin to digital gold, with the possibility of price appreciation.
- Remittances: Bitcoin offers a fast and cost-effective way to send money across borders, reducing fees and transaction times compared to traditional remittance services.
- Exchanges: Platforms allow users to buy and sell bitcoin or exchange it for other cryptocurrencies, facilitating entry and exit from the market.
- Peer-to-peer transactions: Bitcoin enables direct transactions between individuals without intermediaries, promoting financial autonomy and reducing reliance on traditional banking systems. This might sound marginal, but this can be the only way to exchange (digital) money in countries where an authoritarian regime is in power and bank account freezes and seizures are ordinary.
The world Bitcoin is trying to build
At its core, Bitcoin aims to foster financial freedom. By providing a decentralized, secure, and open financial system, Bitcoin empowers individuals and businesses to conduct transactions freely and transparently. This vision aligns with broader goals of promoting financial inclusivity and autonomy in a digitized world. Bitcoin’s potential to offer a stable and accessible financial system is particularly significant in regions with underdeveloped banking infrastructure, unstable national currencies, or authoritarian control over financial institutions.
Bitcoin represents a groundbreaking shift in the way we think about and use money. From its decentralized pseudonymous nature to its growing acceptance and use cases, Bitcoin continues to strive for financial innovation. Whether as a medium of exchange, a store of value, or an investment vehicle, Bitcoin is likely to play a significant role in the future of global finance.
