What is Bitcoin?

Bitcoin is the world’s first cryptocurrency, created in 2009 by an anonymous individual or group known as Satoshi Nakamoto. Built on blockchain technology, Bitcoin laid the foundation for the massive growth of today’s crypto industry. Unlike traditional currencies, Bitcoin operates through a decentralized peer-to-peer network, bypassing intermediaries like banks and financial institutions.

A key feature of Bitcoin is its finite supply of 21 million BTC, ensuring scarcity and long-term value. As of March 2024, around 19.6 million BTC have already been mined, leaving just ~1 million BTC to be created.

Additionally, Bitcoin can be broken down into smaller units called Satoshis (named after its creator). One Bitcoin equals 100 million Satoshis, or 1 Satoshi = 0.00000001 BTC.

How Bitcoin Works

Bitcoin operates on a decentralized public ledger called the blockchain. Each transaction is recorded in a block and linked to previous blocks, forming a chain. The system relies on thousands of nodes (computers) worldwide to verify and store these transactions.

When a transaction is initiated, it is broadcast to the network, where nodes validate its legitimacy by confirming the ownership of the Bitcoin being transferred and verifying the digital signature. Once approved, the transaction is added to a new block, which is appended to the blockchain.

The process of transaction verification and block creation is performed by Bitcoin miners. These miners use computational power to solve complex mathematical problems, a process known as mining. Successful miners are rewarded with newly minted Bitcoin, ensuring a secure and decentralized transaction process.

What Makes Bitcoin Valuable?

Bitcoin’s value stems from several key factors:

1. Decentralization

Bitcoin is free from the control of any central authority, government, or financial institution. Transactions are validated through a consensus mechanism involving multiple nodes globally, ensuring a transparent and democratic process. No single entity can manipulate the network, making Bitcoin resistant to censorship and external control.

2. Security

Bitcoin’s network security is unparalleled due to two main factors:

• Decentralization: To attack Bitcoin, a malicious entity would need to control 51% of the network’s computational power (hashrate). This is virtually impossible due to the enormous cost and infrastructure required. Current estimates suggest that attacking the Bitcoin network for just one hour would cost over $700,000 USD.
• SHA-256 Encryption: Bitcoin employs a highly secure cryptographic algorithm. Even advanced technologies like quantum computing are far from being capable of breaching its defenses. For instance, experts from the University of Sussex estimate that a quantum computer would need 317 million qubits to hack Bitcoin in an hour, whereas today’s most powerful quantum computer has just 127 qubits.

3. Transparency

Unlike traditional currencies, whose supply and usage are often opaque, Bitcoin transactions and supply are fully transparent. All transaction details are stored on the blockchain, which anyone can view, ensuring public accountability.

4. Low Transaction Fees

Bitcoin offers a cost-effective solution for international transactions compared to traditional banking systems. While banks charge a percentage-based fee for cross-border payments, Bitcoin transactions have fixed, relatively low fees, often around $1 per transaction, regardless of the amount sent.

5. Scarcity and Mining Difficulty

Bitcoin’s scarcity (limited to 21 million coins) gives it characteristics similar to digital gold. As Bitcoin’s popularity grows, mining becomes increasingly difficult due to the rising network hashrate. This scarcity, combined with rising mining difficulty, contributes to Bitcoin’s long-term value.

Bitcoin’s Limitations

Despite its success, Bitcoin faces certain challenges:

• Limited block size: Each block can store only 1 MB of data, limiting the number of transactions processed per second.
• Low transaction speed: The network can handle 7 transactions per second, much slower than competitors like Ethereum or traditional payment systems like Visa.
• No smart contract functionality: Unlike Ethereum, Bitcoin does not support smart contracts, limiting its utility beyond being a store of value and medium of exchange.

To address these limitations, solutions like SegWit (Segregated Witness), SegWit2x, and Lightning Network have been proposed and partially implemented.

Ways to Profit from Bitcoin

1. Bitcoin Mining

Mining involves verifying transactions and adding them to the blockchain. Miners are rewarded with two forms of compensation:

• Transaction fees: Paid by users to prioritize their transactions.
• Block rewards: Newly minted Bitcoin given to miners who successfully mine a block.

As Bitcoin matures, block rewards will gradually decrease due to halving events, which occur approximately every four years.

2. Buying and Holding Bitcoin (HODL)

Many investors choose to buy Bitcoin and hold it for the long term, anticipating price appreciation. This strategy relies more on fundamental analysis than technical indicators, requiring confidence in Bitcoin’s long-term growth potential.

How to Store Bitcoin

1. Exchange Storage

Most centralized exchanges (CEXs) like Binance, Coinbase, and OKX offer Bitcoin storage. However, storing large amounts of Bitcoin on exchanges is risky, as demonstrated by the collapse of platforms like FTX.

2. Non-Custodial Wallets

Non-custodial wallets, such as Metamask or Trust Wallet, provide full control over your assets. They come with a public address and a private key or passphrase, which users must store securely. If lost, private keys cannot be recovered, leading to permanent loss of assets.

Risks of Holding Bitcoin

1. Market Volatility

Bitcoin is known for its price volatility, making it a high-risk asset. Historical price fluctuations include:

• April 2021: $63,000 (peak)
• July 2021: $31,000 (drop)
• November 2021: $67,000 (all-time high)
• January 2023: $16,000 (low point)

2. Security Risks

Poor security practices can lead to significant asset losses. Investors are advised to follow best practices, including enabling two-factor authentication (2FA) and using hardware wallets for long-term storage.

3. Regulatory Risks

Bitcoin’s legal status varies by country. Investors should be aware of local regulations to avoid legal complications.

Why Was Bitcoin Created, and What Gives It Value?

Bitcoin’s primary value lies in its decentralization, offering freedom from traditional financial systems. Unlike fiat currencies, which are prone to inflation, Bitcoin’s fixed supply ensures scarcity. For many wealthy individuals, assets like Bitcoin, gold, and real estate provide protection against currency depreciation.

Despite its digital nature, Bitcoin’s immutability and inability to be counterfeited make it an attractive investment. As long as there’s internet access, Bitcoin can be accessed globally without interference.

Institutional Bitcoin Holdings

Many corporations and institutions, including MicroStrategy, Tesla, and Square, hold significant amounts of Bitcoin. While individual holdings are harder to track due to third-party custody services, blockchain data reveals:

• Top 10 holders control 5.4% of the total BTC supply.
• Top 20 holders control 7.4%.
• Top 50 holders control 10.7%.

This distribution indicates Bitcoin’s decentralized ownership, preventing any single entity from dominating the market.

Conclusion: Should You Invest in Bitcoin?

Bitcoin represents a unique opportunity as a decentralized, scarce digital asset with long-term growth potential. However, its volatility, security risks, and regulatory uncertainties necessitate careful consideration and thorough research. By understanding its fundamentals and implementing proper risk management, investors can navigate the Bitcoin market with greater confidence.

As Bitcoin continues to evolve, its role as “digital gold” and a hedge against inflation could further solidify its place in global finance.
