In 2008, the global financial system nearly collapsed. Banks had taken enormous risks with people’s money, governments printed billions to bail them out, and ordinary people lost their savings, homes and jobs.
A mysterious person — or group — using the name Satoshi Nakamoto had seen enough. In October 2008, they published a document called the Bitcoin Whitepaper — just 9 pages that would change the world forever.
On January 3, 2009 — Bitcoin was born.
Bitcoin is digital money that exists only on the internet. But unlike PayPal, bank transfers or credit cards — nobody controls it.
Think of it this way:
When you send money via your bank — your bank can freeze it, reverse it, charge fees, or refuse the transaction. Bitcoin removes the bank completely. You send directly to another person — anywhere in the world — in minutes.
Bitcoin has three core properties that make it unique:
1. Decentralized
No government, bank or company controls Bitcoin. It runs on thousands of computers worldwide simultaneously. To shut it down — you would need to shut down the entire internet.
2. Fixed Supply
Only 21 million Bitcoin will ever exist. This is written into the code and cannot be changed. Compare this to the US dollar — where the government printed 40% of all dollars ever in existence in just 2020-2021.
3. Transparent
Every single Bitcoin transaction ever made is recorded on a public ledger called the blockchain. Anyone can verify any transaction. Nothing is hidden.
Many people ask — “but it’s not physical, why does it have value?”
The same question could be asked about paper money. A $100 bill is just paper — it has value because people agree it does.
Bitcoin has value because:
Bitcoin is often called Digital Gold — and for good reason:
Gold:
Bitcoin:
Bitcoin takes everything gold does well — and does it better in the digital age.
Every 4 years — the reward for mining new Bitcoin is cut in half. This is called the Halving.
This means Bitcoin becomes more scarce over time. Historically — every halving has been followed by a major price increase.
The next halving was in April 2024.
Bitcoin itself has never been hacked. The blockchain is mathematically secure.
However — exchanges and wallets can be hacked. This is why the golden rule is:
“Not your keys, not your coins” — if you don’t control your private key, you don’t truly own your Bitcoin.
In the next topic we will learn exactly how the blockchain works.
