Bitcoin has undergone tremendous growth and periods of disillusionment since its inception in 2009. Starting with a valuation of $0.08 per coin in 2010, Bitcoin has evolved into a successful institutional investment asset held by companies like Tesla, Square, and MicroStrategy. It’s also recognized as a global currency accepted by fintech giants such as PayPal and Mastercard. The year 2020 marked a significant milestone for Bitcoin as it achieved broader mainstream adoption and surpassed its 2017 all-time high before the historic crash.
Critics argue that Bitcoin’s price volatility makes it a speculative asset at best and a channel for criminal activities like money laundering at worst. However, proponents highlight Bitcoin’s resilience during the pandemic and its role as digital gold, signaling an inevitable shift in our perception of money.
Regardless of your stance, Bitcoin’s growing influence in an era of unprecedented fiscal policies and accelerated digital transformation is undeniable. While widespread acceptance as a monetary asset is still underway, Bitcoin challenges our understanding of decentralized currency and the traditional financial system.
Understanding Money: The Foundation of Bitcoin
Before diving into Bitcoin, it’s crucial to grasp the concept of money. Historically, money has taken various forms—from commodities (e.g., cattle, shells) to precious metals (e.g., silver, gold) and fiat currencies (e.g., USD). The modern financial system relies on centralized authorities (e.g., central banks) to maintain monetary functions. While efficient, this system carries risks, as seen in the 2008 financial crisis and hyperinflation episodes like Venezuela’s since 2016.
Key Functions of Money:
- Medium of exchange (facilitates transactions)
- Store of value (retains purchasing power)
- Unit of account (measures economic value)
Bitcoin redefines these functions through decentralization, eliminating reliance on intermediaries like banks.
What Is Bitcoin and How Does It Work?
Bitcoin is a decentralized digital asset operating on a blockchain network. Users store and transact Bitcoin via wallets (software/hardware-based, e.g., Coinbase, Ledger).
Bitcoin Transactions Explained
- Inputs: Existing Bitcoin funds tracked by the wallet.
- Outputs: Recipient’s address + change (if applicable).
Process:
- Ownership is verified via digital signatures.
- Outputs are generated, and fees are paid.
- Verified inputs transfer to the new owner’s address.

Bitcoin Mining: Building the Blockchain
Transactions are validated through Proof-of-Work (PoW):
- Miners solve complex math problems to verify transactions.
- Successful miners add blocks to the blockchain, earning new Bitcoin as a reward.
- Each block contains multiple transactions, creating an immutable ledger.
Key Insight:
- Mining ensures trustless consensus—no central authority is needed.
- Network security grows as more blocks are added (~6 confirmations make reversal nearly impossible).
Risks and Challenges
- Volatility: Prices can swing drastically within seconds.
- Scalability: Processes 3–7 transactions/second vs. Visa’s 24,000 TPS.
Security:
- Lost credentials = permanently lost Bitcoin.
- Exchange hacks (e.g., $292M stolen in 2019).
