Entering the cryptocurrency world a year ago marked the beginning of an irreversible journey. Recently, with global blockchain advocacy and increasing media coverage, Bitcoin and blockchain technology have gained broader acceptance. What was once dismissed as gambling by my father is now a topic of regular investment discussions among friends. This shift inspired me to share insights about Bitcoin and the crypto space.
The Origins of Bitcoin
Bitcoin (BTC) is a blockchain-based cryptocurrency created by Satoshi Nakamoto, who published the groundbreaking whitepaper, "Bitcoin: A Peer-to-Peer Electronic Cash System", in November 2008. Nakamoto vanished years later, leaving behind a legacy shrouded in mystery. Despite numerous claims (e.g., "Craig Wright"), Nakamoto’s true identity remains unknown. Clues suggest they may be British (based on use of British English) and not residing in Japan (due to inactivity during Japanese daytime hours).
Purpose of Bitcoin
Bitcoin was designed to function as a decentralized digital currency, enabling peer-to-peer (P2P) transactions without intermediaries like banks. Its goal is to facilitate cross-border payments—e.g., someone in Taiwan could instantly transact with someone in the UK or Congo using BTC.
Key Technologies and Features
Core Characteristics:
- Decentralization: No central authority controls the network.
- Transparency: All transactions are publicly recorded on the blockchain.
- Anonymity: Users interact via cryptographic addresses (e.g.,
1GhtqG8EMHP...). - Immutability: Altering past transactions requires consensus across the entire network, making fraud nearly impossible.
How It Works:
- The blockchain acts as a distributed ledger, where every participant maintains a copy of the transaction history.
- Transactions are verified by network nodes and grouped into "blocks," which are cryptographically linked ("chained") to ensure integrity.
Current Applications and Limitations
Challenges:
- Bitcoin processes ~7 transactions per second (TPS), leading to congestion.
- Scalability issues spurred alternatives like Ethereum (ETH) and EOS, which offer faster speeds and lower fees.
Practical Use Case: Cross-Border Currency Exchange
Example: Converting 1,000 GBP to TWD via Bitcoin (data from 2020):
- Traditional Bank: Fees include wire transfer charges (0.05% + fixed costs).
BTC Method: Purchase BTC locally, sell on platforms like LocalBitcoins for GBP.
- Cost: ~38,335 TWD (including fees).
- Time: ~30 minutes (longer during network congestion).

FAQ
Q1: Is Bitcoin legal?
A: Most countries permit BTC, but regulations vary. Some ban it entirely (e.g., China), while others classify it as property (e.g., USA).
Q2: How can I store Bitcoin safely?
A: Use hardware wallets (e.g., Ledger) or cold storage for maximum security.
Q3: Why does Bitcoin’s price fluctuate so much?
A: Limited supply (21 million BTC) and speculative demand drive volatility.
Q4: Can Bitcoin replace traditional currencies?
A: Unlikely in the short term due to scalability and regulatory hurdles, but it’s gaining traction as a store of value.
