What is Bitcoin (BTC)?

1. What is Bitcoin? Background

Bitcoin (BTC) is the world’s first cryptocurrency (digital asset). Its concept was introduced in 2008 in a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” by a mysterious individual or group known as Satoshi Nakamoto.

In 2009, the first Bitcoin block (the genesis block) was mined, and the Bitcoin network officially went live.

Bitcoin was created to provide a decentralized digital currency that enables direct transactions between individuals without a central authority, allowing value to be stored and transferred independently of governments or banks.

2. Characteristics of Bitcoin

Bitcoin has several unique features that set it apart from other cryptocurrencies:

  • It operates without a central authority. Rather than being controlled by banks or governments, the network is maintained by all participants.
  • It uses blockchain technology. All transactions are recorded on a distributed ledger called a blockchain, which is designed to be tamper-proof.
  • Its supply is limited. The total supply of Bitcoin is capped at 21 million BTC, and the amount of new Bitcoin issued decreases over time through a process known as halving.
  • It is issued through mining. New Bitcoins are created via mining, where miners use computing power to verify transactions and receive newly issued Bitcoins as a reward.
  • It is highly secure. Strong cryptographic protocols make hacking and unauthorized access extremely difficult.

3. How Bitcoin Works

Bitcoin relies on a consensus algorithm known as Proof of Work (PoW) to ensure transaction validity.

  • Transaction approval: Transactions are verified by nodes (computers) in the network and then recorded on the blockchain.
  • Block creation: Miners solve complex computational puzzles to generate new blocks, which include the approved transactions.
  • Halving: Approximately every four years, a halving event occurs, reducing the reward for miners by half. This mechanism limits the issuance of new Bitcoins and increases their scarcity.

In 2012, the reward dropped from 50 BTC to 25 BTC.

In 2016, it fell from 25 BTC to 12.5 BTC.

In 2020, it decreased from 12.5 BTC to 6.25 BTC.

In 2024, the reward will drop from 6.25 BTC to 3.125 BTC.

Halving will continue periodically, and it is expected that all Bitcoins will have been mined by around the year 2140.

4. Price History of Bitcoin

Bitcoin’s price has experienced significant fluctuations over the years:

  • 2009: Bitcoin transactions began, and the price was nearly zero.
  • 2010: The first recorded price emerged when 10,000 BTC were exchanged for two pizzas (approximately $0.0025 per BTC).
  • 2013: Bitcoin surpassed $1,000 per BTC.
  • 2017: During the cryptocurrency boom, Bitcoin reached around $20,000 per BTC.
  • 2018: Following the bubble burst, the price fell sharply to the $3,000 range.
  • 2021: Bitcoin hit an all-time high of about $69,000 per BTC.
  • 2022: The collapse of FTX and other market downturns pushed Bitcoin down to the $15,000 range.
  • 2023–2024: Bitcoin recovered, trading in the $40,000 to $50,000 range.

Future prices will likely depend on regulatory developments, institutional investments, and the effects of halving.

5. What Beginners Should Know

Before investing in or using Bitcoin, consider the following points:

  • Bitcoin is highly volatile, with significant price swings over short periods. A long-term holding strategy is generally advisable.
  • Self-custody is crucial. Since there is no central authority managing Bitcoin, you are responsible for your own wallet. Storing Bitcoin on an exchange can expose you to hacking risks, so consider using a hardware wallet for added security.
  • Be cautious of scams. Avoid fraudulent investment schemes and fake websites by relying on official sources and trusted information.
  • Understand the tax implications. Profits from Bitcoin trading are taxable in many countries, so keep detailed transaction records and comply with tax reporting requirements.

6. The Future of Bitcoin (Outlook Beyond 2025)

Looking ahead, several trends may shape the Bitcoin market:

  • Increased institutional participation: The growing availability of Bitcoin ETFs may attract more institutional investors, potentially leading to greater price stability.
  • Tighter regulatory frameworks: As regulations become more established, they may help prevent illegal activities and increase transparency, though overly strict rules could negatively affect prices.
  • Post-halving price trends: Following the 2024 halving, the reduced supply of new Bitcoins may drive prices higher, based on historical patterns, though overall market conditions and macroeconomic factors must also be considered.
  • Broader adoption as a payment method: With countries like El Salvador already adopting Bitcoin as legal tender, more businesses and nations might begin to accept Bitcoin for payments in the future.

Conclusion

Bitcoin is the first decentralized digital currency, operating without a central authority. Its capped supply of 21 million BTC, coupled with periodic halving, contributes to its scarcity. Despite experiencing dramatic price fluctuations, Bitcoin continues to attract long-term interest from institutional investors. Future growth will be influenced by regulatory changes and technological innovations.
