How Bitcoin Works

• Bitcoin operates on a decentralized system known as blockchain technology, where transactions are verified and recorded across a distributed network of computers instead of a central authority.
• When a user sends Bitcoin, the transaction is broadcast to the network and grouped into blocks.
• These blocks are then validated by miners using computational power through a process called proof-of-work.
• Once verified, the block is added to the blockchain, creating a permanent and transparent record that cannot easily be altered.
• This system ensures trust without intermediaries like banks, making Bitcoin secure and censorship-resistant.
• Transactions typically take around 10 minutes to confirm, although this can vary depending on network congestion and fees paid.

The History and Development of Bitcoin

• Bitcoin was introduced in 2008 through a white paper titled Bitcoin: A Peer-to-Peer Electronic Cash System by Satoshi Nakamoto.
• In 2009, the first Bitcoin software was released, and the genesis block was mined, marking the beginning of the network.
• Early adopters like Hal Finney helped test and develop the system, while Gavin Andresen later became a leading figure in its development.
• Over time, Bitcoin gained traction as more businesses and users adopted it, especially between 2013 and 2017 when exchanges and payment processors expanded rapidly.
• Governments and financial institutions gradually began recognizing Bitcoin’s role, contributing to its growth as both a digital asset and an alternative financial system.
• Today, Bitcoin is widely regarded as the first successful cryptocurrency and remains the most dominant in market value and adoption.

What makes Bitcoin so valuable?

• One of the key factors that determines the value of Bitcoin is that it was the first cryptocurrency to be created, in addition to the fact that it is the first recognized currency over which no person, organization, or authority has control.
• It can be bought, sold, and received, but no one can be told what to do with it or how it should be spent or invested.
• Bitcoins are free from dictatorship, oppression, and hyperinflation. It serves a purpose as a safe haven for individuals who live and have lived under these circumstances.
• There is a limited supply of Bitcoin, which is another factor that makes it so valuable. There are only 21 million Bitcoins, and there will never be more created than this.
• In addition, there is complete transparency surrounding the knowledge of how many there are, the rate at which they are released, and when the last Bitcoin will be created or released.
• Bitcoin possesses a substantial amount of leverage over fiat currencies, as they can be controlled by central banks and governments, who have control over conventional monetary systems.
• Monetary systems are controlled and manipulated as there is a certain supply of money, and it is backed by the word of governments. This is only one of many controversial issues surrounding fiat currencies that cannot be applied to Bitcoin.
• Bitcoin presents a unique design, and it is poised to have an impact on the lives of people despite the unstable economies where monetary systems are greatly manipulated by key players such as banks and governments, among others.

Why is Bitcoin exchanged?

Bitcoin is an efficient way to make a profit. There is a lot of stigma that exists around how profit can be made from trading something that technically does not exist, as it cannot be seen, touched, or physically handled. There is also a lot of belief that the only way that profit can be made when trading currencies is when major currency pairs are traded, but this is slowly changing as more brokers and traders start embracing cross pairs between crypto and fiat currencies. Successful traders do not only focus on one currency pair through which to make a profit, and a lot of traders have started trading cross pairs. Cross pairs often provide a higher level of market volatility, and this is increasing as more of it is being traded in the markets.   The presence and onset of high volatility is but one reason why traders consider moving from fiat currency trading to trading cryptocurrencies or focusing more on cross pairs. Some of the main reasons surrounding this include:

• The market movements are easy to understand as the focus is not merely on major trends. Buying and selling Bitcoin is an easy way to make profits once traders have learned more about trading in theory and by practicing trading.
• The price of Bitcoin is less susceptible to high-impact news, and traders are not forced to spend as much time doing fundamental analysis.
• Bitcoin trading does not involve leverage as high as with other instruments, and this significantly reduces the risk of losses.
• There is a global market for Bitcoin as it is not centralized or based in one country's economy, as is the case with fiat currencies.
• The Cryptocurrency Market is open 24/7, unlike traditional markets such as Forex or stocks, and there is no official exchange. Instead, there are a variety of exchanges around the globe without fixed closing and/or opening times.
• The Bitcoin market is volatile and features quick bursts of up and down price movements in a short amount of time. This provides traders with ample opportunity to harness the volatility with strategies that accommodate the conditions.

How are new Bitcoins created and generated?

• All Bitcoin transactions are processed by miners. Miners secure the Bitcoin network and provide a level of security against attacks, as these would render the network vulnerable, and it would inevitably become useless.
• For their efforts, security, and processing services, miners are rewarded with both Bitcoins and a certain amount of transaction fees, which vary between brokers and exchanges.
• Every time a miner successfully solves the proof of work algorithm of Bitcoin, the miner has mined a block. The miner, or mining pool, is rewarded a block through what is commonly referred to as a ‘block reward’.
• The reward is made up of a set number of Bitcoins agreed upon by the network. It should be noted that the Bitcoins that make up the block reward are all new Bitcoins.
• There are 50 Bitcoins per block, and the blocks halve every 210,000 blocks. Every block up until this point rewards miners with 50 Bitcoins, and as soon as it is halved, for instance, when block 210,001 is mined, the reward would only be 25 Bitcoins.
• The process involved with mining Bitcoin presents some level of difficulty to ensure that blocks are only found on average every 10 minutes. When considering that blocks halve with every 210,000 blocks mined, it means that blocks halve every four years.
• There are, therefore, new Bitcoins generated every 10 minutes when a block is mined. This can be publicly verified by making use of a block explorer, and provides some insight into the level of transparency there is in Bitcoin trading.
• With the block reward halving a set number of times, the blocks will become so small in time that new Bitcoins cannot be created.

How is Bitcoin exchanged or traded?

    Bitcoin can be bought, sold, exchanged, and traded in a variety of ways, including:

• Trading Bitcoin – there are numerous brokers who make Bitcoin a part of their offering as a tradable financial instrument, such as CFDs.
• Bitcoin or cryptocurrency exchanges – such as Coinbase, Binance, Kraken, and others. Each exchange works in a different manner, and some are either decentralized or centralized.
• Peer-to-peer – sites such as LocalBitcoins allow for the buying and selling of Bitcoin directly between two participants with little to no intervention from the facilitator.
• Bitcoin ATM – these are quite popular in major cities around the world and offer the opportunity for Bitcoin to be bought and sold.

What is a Crypto or Bitcoin Wallet?

• As an actual wallet is used to store cash and bank cards, a Crypto wallet is used to store cryptocurrencies.
• It is a software program, due to the digital nature of cryptocurrencies, in which Bitcoin can be stored.
• Cryptocurrencies cannot be stored anywhere as they carry significant monetary value.
• They require safe storage that has a private key or secret number.
• These keys are designated for every individual who has a balance in a Bitcoin wallet.
• The key or number corresponds to the Bitcoin wallet address.
• Bitcoin wallets work for the sending and receiving of Bitcoin, in addition to providing ownership of the Bitcoin it contains to the user.
• Bitcoin wallets are not confined to only one given platform, and it is possible for a wallet to be accessed from a desktop, mobile device, a web browser, or even other hardware.
• To exchange Bitcoins, it is necessary for traders to be in possession of a Bitcoin wallet. Due to the digital nature of Bitcoin, it cannot be stored physically.
• Instead, the wallet stores relevant information such as private keys to Bitcoin addresses.

What are the different types of Bitcoin wallets available?

Desktop Wallets

• These wallets are created with the purpose of being downloadable onto and used by personal computers and laptops.
• These wallets can be accessed even when a trader is not connected to the internet.

  Desktop Wallets can be downloaded onto laptops and desktops that run the following operating systems:

• Ubuntu
• MacOS, and
• Microsoft Windows.

  One of the most popular and most used Bitcoin wallets on the market at the moment is Armory. It has vast and advanced safety features and ease of use.  

Mobile Wallets

• With the advent of technology and the move towards a more digitally portable trading industry, along with trades being executed on mobile devices, it is only fair that Bitcoin wallets can be accessed on mobile devices.
• Mobile Bitcoin wallets can be downloaded onto most smartphone devices. They offer a lot more convenient access to the wallet and provide ease of access, whether the trader is connected to the internet or not.
• Two of the most popular wallets developed for mobile devices are Blockchain and Mycelium. Both can be downloaded for use on Android and iOS devices.
• Users of BlackBerry mobile devices can make use of a Bitcoin app, which can be downloaded and installed.
• With mobile devices and the corresponding Bitcoin wallets, users can easily make use of QR codes, which allow them to make instant payments from their Bitcoin wallets, much like banking apps do.

Cold Wallets and Hot Wallets

• A Cold Bitcoin wallet refers to one that is not connected to the internet and thus offline.
• This type of wallet is considered the most secure of the two types as it provides added protection from hackers.
• A Hot wallet is an online wallet that is connected to the internet.
• This poses a security threat as they are mostly targeted by hackers.
• Traders are advised to keep both types of wallets. A cold wallet is recommended for the storage of larger sums of Bitcoin, whereas the hot wallet is merely used when transacting, trading, or making everyday purchases in Bitcoin.

Online Web Wallets

• These types of wallets are connected to the internet, as the name suggests.
• They are accessed through cloud services by third parties and grant traders access to their Bitcoin wallet.
• Developers and providers of such wallets include Circle and Coinbase.

Physical Wallets

Due to the nature of Bitcoin, this may seem to contradict; however, these wallets, also known as paper wallets, are generated by Blockchain.info and Bitaddress.org and feature a physical copy of the Bitcoin address and private keys, which can be printed and stored safely.  

Hardware Wallets

• These are small devices that store the user’s Bitcoin and can be used for sending and receiving Bitcoin through online transactions.
• One such device is Trezor, which is becoming an increasingly popular portable physical crypto wallet.

Bitcoin Clients

• These are the original wallets that were used by the founders of Bitcoin.
• The computers that have these wallets installed are being sold in the community and provide online trading clients with access to all transactions executed through the Blockchain.

How to Buy Bitcoin

• Buying Bitcoin has become increasingly accessible, especially in regions like South Africa, where multiple exchanges and platforms support local currency deposits.
• The process typically involves selecting a reputable cryptocurrency exchange, creating an account, and completing identity verification (KYC).
• After funding your account using bank transfer, card, or other supported methods, you can purchase Bitcoin at the current market price or set a custom order.
• Once purchased, it is strongly recommended to transfer your Bitcoin to a secure wallet rather than leaving it on an exchange.
• This reduces exposure to hacking risks and gives you full control over your assets.
• Some users also use peer-to-peer platforms or Bitcoin ATMs, though exchanges remain the most common and user-friendly method.

Is it better to pay in Bitcoin than other methods of payment?

• Paying with Bitcoin offers a different value proposition compared to traditional payment methods like bank transfers, cards, or e-wallets.
• Whether it is “better” depends on the use case — but Bitcoin stands out in areas like control, speed, and global accessibility.
• Unlike traditional finance systems, Bitcoin operates on a decentralized network, meaning users can send and receive payments without relying on banks or payment providers.
• This removes many of the restrictions, delays, and fees typically associated with fiat-based transactions.
• As adoption grows, more merchants worldwide are accepting Bitcoin, making it a practical alternative payment method in certain scenarios.
• However, Bitcoin is not always superior in every situation. While it offers strong advantages in privacy and cross-border transfers, it also comes with trade-offs such as price volatility and irreversible transactions.
• Understanding both sides is essential before choosing Bitcoin as a primary payment method.

How is Bitcoin bought, sold, traded, or exchanged?

Through a Cryptocurrency Exchange Platform

Considering that there is no singular or official exchange through which Bitcoin can be traded, sold, or bought, there are numerous cryptocurrency exchange platforms that facilitate such transactions.   The process involved with choosing a Cryptocurrency Exchange Platform is one that requires thorough research, and traders and investors need to consider a few vital factors, such as:

• Both the liquidity and the market depth of the exchange. There needs to be an adequate amount of both to ensure that orders can be filled. It also decreases the chances of a quick dip in the market that may result in losses.
• Trading or transaction fees are charged by the exchange for its services. Fees should be low, as it allows the trader to exit, despite how small the movements are, which will cover the fee and allow traders to make a small profit.
• The location of the exchange and whether it allows fiat deposits or withdrawals. This allows traders to deposit and/or withdraw in their own currency.
• Regulation and trust – the crypto market is, for the greater part, unregulated, but this does not mean that it cannot be trusted. Traders must investigate the history of the exchange and the current security measures that they have in place.

Brokers

• Bitcoin is offered by numerous brokers as a CFD instrument, and the process of choosing a broker may be tedious, as there are a great number of brokers in the industry.
• It is imperative for traders to look at several factors when considering trading through a broker, such as regulation, fees, spreads, commissions, funding options, education, and more.

  When using a broker to facilitate the trade in Bitcoin, traders need to ensure that they keep the following in mind:

• The amount and variety of Cryptocurrency pairs offered
• Accessible and reliable payment methods are offered
• The quality and usability of the trading platforms offered, and
• The level and quality of customer support offered.
