Bitcoin (BTC) stands as the original and the most significant cryptocurrency, boasting a market capitalization of approximately $826 billion as of February 7, 2022. However, Bitcoin’s significance extends beyond mere cryptocurrency; it is the bedrock upon which thousands of other digital currencies have been built, following in its decentralized, digital footsteps.

How Does Bitcoin Work?

Comprehending the workings of Bitcoin is akin to deciphering the underpinnings of the broader cryptocurrency ecosystem.

How Does Bitcoin Work

Bitcoin relies on blockchain technology, a transparent, open-source digital ledger that meticulously records every transaction. Its decentralized nature means it operates via a sprawling network of powerful computers, often referred to as miners or nodes. These miners validate transactions through a proof-of-work (PoW) consensus mechanism. This peer-to-peer network of miners is self-regulating, obviating the need for intermediaries such as banks or financial institutions.

In stark contrast to traditional currencies like the U.S. dollar, Bitcoin is not overseen, issued, or regulated by a central authority. Instead, Bitcoin laid the groundwork for the cryptographic and consensus-driven systems that are the bedrock of most contemporary cryptocurrencies.

The Significance of Bitcoin Mining

Bitcoin mining serves a dual role; it is the process through which new BTC is created and the mechanism through which transactions are validated, enhancing network security.

When a Bitcoin transaction is initiated, it is forwarded to miners for validation. These miners utilize robust computers, often referred to as mining rigs, to perform the complex PoW calculations necessary for confirming each transaction on the blockchain.

Miners who successfully validate a block of transactions (typically 1 MB in size) receive newly created Bitcoin as a reward. The competitive nature of mining, coupled with the fact that mining rewards halve approximately every 210,000 blocks, currently yielding 6.25 BTC, underscores the significance of mining to maintain network security. For a malevolent entity to seize control of the blockchain and pilfer Bitcoin, they would need to commandeer over 51% of the network, offering miners a substantial incentive to uphold network integrity.

Peer-to-Peer Technology

Bitcoin was a trailblazer in harnessing peer-to-peer (P2P) technology for facilitating rapid payments and transactions, devoid of intermediaries like banks. The foundation for this system can be traced back to the 2008 whitepaper, “Bitcoin: A Peer-to-Peer Electronic Cash System.” This framework aimed to resolve the age-old double-spend problem, a historical stumbling block in digital currency development.

The whitepaper elucidated this concept by stating, “A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work.”

This P2P verification system hinges on encryption and blockchain technology to enable secure transactions between two parties without the need for a third party. This not only enhances security but also makes fraudulent transactions exceptionally difficult.

As of the first quarter of 2022, the U.S. Securities and Exchange Commission (SEC) deliberated on cryptocurrency regulation.

Who Created Bitcoin (BTC)?

In 2008, an individual or group operating under the pseudonym Satoshi Nakamoto published the seminal whitepaper, “Bitcoin: A Peer-to-Peer Electronic Cash System.” This groundbreaking document proposed a trustless system for electronic transactions. By doing so, it eliminated the necessity for third-party oversight while simultaneously resolving the double-spend problem, ensuring the permanence and transparency of all Bitcoin transactions.

Bitcoin’s Historical Timeline

Understanding Bitcoin’s evolution in the financial landscape requires a glimpse into its early history:

  • August 18, 2008: The domain name Bitcoin.org was registered, although the identity of the registrant remained undisclosed.
  • October 31, 2008: Satoshi Nakamoto, a pseudonymous entity, released the whitepaper “Bitcoin: A Peer-to-Peer Electronic Cash System,” a document that laid the foundation for Bitcoin and the broader crypto market.
  • January 3, 2009: The genesis block, or Block 0, was mined. Notably, it contained a reference to a headline from that day, potentially denoting the date of mining or a political commentary.
  • May 22, 2010: Celebrated as Bitcoin Pizza Day, a Florida-based early Bitcoin adopter exchanged 10,000 BTC for two pizzas, marking one of the earliest instances of a real-world trade involving Bitcoin.
  • 2011: Bitcoin’s value exceeded $1, while other cryptocurrencies such as Ethereum and Litecoin emerged, showcasing the expanding potential of crypto and blockchain technology.
  • 2013: Bitcoin witnessed a surge, reaching $200 in February and subsequently surging to $1,000 in November, emblematic of the volatility characterizing most cryptocurrencies.

Why Does Bitcoin (BTC) Possess Value?

Bitcoin shares traits with both commodities and fiat currencies, which have collectively endowed it with value. These traits include durability, portability, acceptability, and scarcity.

  • Durability: Each Bitcoin, residing on the blockchain, is resistant to replication, much like a physical dollar’s durability. BTC private keys, comprising alphanumeric characters, can be engraved on stainless steel, backed up, or divided into segments, further enhancing their longevity.
  • Portability: Bitcoin’s digital nature, coupled with the individual private keys associated with each coin, enables users to carry their assets wherever they go, whether through a cold wallet, a hot wallet on a mobile device, or an exchange.
  • Acceptability: Bitcoin is listed on numerous crypto exchanges and is recognized as a store of value. Notably, it is increasingly accepted for real-world transactions, with thousands of individuals and vendors now embracing it as a payment method.
  • Scarcity: A key allure of Bitcoin lies in its limited supply. A mere 21 million BTC will ever circulate. As of February 2022, nearly 19 million BTC have been mined, but the rate of new coin issuance halves approximately every four years. This scarcity ensures that the total supply remains finite.

Bitcoin’s Price

As of February 7, 2022, Bitcoin’s price stood at approximately $43,000, with a market capitalization exceeding $817 billion. Its circulating supply was over 18.95 million BTC. However, the highly volatile nature of Bitcoin was evident in 2021 when its price ranged from a low of about $29,800 in July to a peak of over $68,000 in November.

Why Use Bitcoin (BTC)?

Bitcoin’s status as the oldest and most recognized cryptocurrency lends it an edge over its competitors. It is widely available for trading on most exchanges, serves as a store of value, and is increasingly embraced by companies for the purchase of goods and services. Primarily, people employ Bitcoin as an alternative investment, diversifying their portfolios beyond conventional assets such as stocks, bonds, mutual funds, and ETFs.

  2. Complete the Trade: Upon the completion of the transaction, the funds will remain within your Invest Account.
  3. Tax Considerations: Be vigilant about tax implications associated with cryptocurrency transactions.

How to Store Bitcoin?

Ensuring the security of your Bitcoin involves safeguarding it against theft, fraud, and hacking. To store Bitcoin securely, you can choose between hot wallets and cold wallets:

  • Hot Wallet: Digital currency is stored in the cloud on reputable exchanges or service providers and is accessible via the internet, either through a computer or a mobile app. However, hot wallets are susceptible to online vulnerabilities.
  • Cold Wallet: These encrypted portable devices, akin to thumb drives, allow the download of private keys for Bitcoin. They are not connected to the internet but can be vulnerable to physical loss.

It is worth noting that you typically need a hot wallet to transfer Bitcoin to a cold wallet for long-term storage.

Other Bitcoin Investment Avenues

Apart from direct buying and selling of BTC, you can explore investment opportunities through Bitcoin-related exchange-traded funds (ETFs). Notably, these ETFs provide indirect exposure to Bitcoin and its underlying technology due to regulatory debates concerning the classification of crypto as securities.

Debate About Crypto’s Regulatory Status

Numerous endeavors have been made to create crypto-related securities since Bitcoin’s inception in 2009. Yet, the U.S. Securities and Exchange Commission (SEC) has been cautious about granting approval. This hesitancy arises from the unregulated nature of Bitcoin and most other cryptocurrencies. As of now, the SEC treats Bitcoin more as a commodity that serves as a store of value, similar to assets like gold or oil, rather than a security. The ongoing debate bears significant implications for the cryptocurrency landscape.

Bitcoin ETFs

In October and November 2021, the first three Bitcoin ETFs became available in the United States. These ETFs are linked to Bitcoin futures contracts rather than the daily market price of Bitcoin. It’s essential to comprehend that these funds do not invest in physical Bitcoin assets but focus on cash-settled contracts traded on the Chicago Mercantile Exchange (CME).

No Staking in Bitcoin

Bitcoin operates on a proof-of-work consensus mechanism, rather than proof-of-stake, precluding investors from staking Bitcoin for rewards.


Bitcoin’s significance extends far beyond being the first and foremost cryptocurrency. Since its inception in January 2009, Bitcoin has not only laid the foundation for the broader cryptocurrency ecosystem but has also propelled the development of blockchain technology, decentralized networks, and various innovations like decentralized applications (dApps), smart contracts, and non-fungible tokens (NFTs).

This enduring legacy of Bitcoin, originating as an idea in the anonymous whitepaper of 2008, has profoundly shaped the financial landscape, offering a decentralized form of currency underpinned by blockchain technology and governed by a peer-to-peer network. Today, this concept is no longer novel, as it has fostered the growth of a vast ecosystem comprising cryptocurrencies, altcoins, tokens, and more.
