What is Bitcoin?
A beginner-friendly guide to understanding Bitcoin, blockchain technology, and why it matters for Singapore investors in 2026.
Bitcoin in Simple Terms
Bitcoin (BTC) is a digital currency -- also called a cryptocurrency -- that allows you to send and receive value over the internet without needing a bank or middleman. It was created in 2009 by an anonymous person (or group) known as Satoshi Nakamoto.
Think of Bitcoin like digital gold: it's scarce (only 21 million will ever exist), it can be divided into tiny fractions (called satoshis), and it operates on a global network that runs 24/7, 365 days a year.
Bitcoin Key Facts
Maximum Supply

Year Created
By anonymous creator Satoshi Nakamoto
Block Time
New block every ~10 minutes
Peer-to-Peer
No banks or intermediaries needed
How Does Blockchain Work?
Bitcoin runs on a technology called blockchain -- a public, digital ledger that records every transaction ever made. Imagine a shared spreadsheet that thousands of computers maintain simultaneously, where no single person can alter past entries.
Transaction Initiated
You send Bitcoin to someone. The transaction is broadcast to the Bitcoin network.
Miners Verify
Thousands of computers (miners) compete to solve a mathematical puzzle and verify your transaction.
Block Created
Verified transactions are grouped into a "block" and added to the chain. Each block is linked to the previous one.
Transaction Complete
The transaction is now permanently recorded on the blockchain. It cannot be reversed or altered.
Why People Invest in Bitcoin
Store of Value
Like gold, Bitcoin's limited supply (21 million) makes it a hedge against inflation. As more money is printed globally, Bitcoin's scarcity becomes more valuable.
Decentralization
No single government or company controls Bitcoin. It operates on a global network of thousands of computers, making it resistant to censorship.
Portfolio Diversification
Bitcoin has a low correlation with traditional assets like stocks and bonds, making it a useful addition to a diversified investment portfolio.
Growing Adoption
Major institutions (BlackRock, Fidelity), countries (El Salvador), and companies (Tesla, MicroStrategy) now hold Bitcoin. Spot Bitcoin ETFs launched in 2024.
Bitcoin Halving
Every ~4 years, the reward miners receive for verifying transactions is cut in half. This event, called the "halving," reduces the rate of new Bitcoin entering circulation, increasing scarcity. The most recent halving occurred in April 2024, reducing the block reward from 6.25 BTC to 3.125 BTC.
Historical Pattern: Previous halvings (2012, 2016, 2020) have each been followed by significant price increases within 12-18 months. While past performance doesn't guarantee future results, many investors view the 2024 halving as bullish for Bitcoin's price in 2025-2026.
Risks to Consider
-
High Volatility
Bitcoin's price can swing 10-20% in a single day. Never invest more than you can afford to lose.
-
Security Risks
Lost private keys mean lost Bitcoin forever. Use strong passwords, 2FA, and consider hardware wallets.
-
Regulatory Changes
While Singapore is currently crypto-friendly, regulations can change. Stay informed about MAS updates.
-
Scams
Beware of fake exchanges, phishing emails, and "guaranteed return" schemes. Only use MAS-licensed platforms.
