What Is Bitcoin?
Bitcoin is a decentralized digital currency that allows people to send and receive money over the internet without banks or central authorities. It operates on a public blockchain network where transactions are verified by distributed computers instead of a single institution.
Launched in 2009, Bitcoin introduced a new financial model based on transparency, scarcity, and mathematical rules rather than trust in intermediaries.
Bitcoin Explained in 4 Layers
1.Technology Layer
Bitcoin runs on blockchain technology and cryptographic verification.
2.Monetary Layer
Supply is capped at 21 million coins, creating digital scarcity.
3.Network Layer
Thousands of independent nodes validate transactions globally.
4.Market Layer
Price fluctuates based on supply, demand, sentiment, and liquidity.
1. Why Was Bitcoin Created?
Bitcoin was created in response to weaknesses in traditional financial systems. During financial crises, banks and institutions can fail, freeze withdrawals, or require government intervention. Bitcoin was designed to function independently of these systems.
Its goal was to create a form of money that follows transparent rules, cannot be easily manipulated, and does not rely on trust in a single authority.
2. How Bitcoin Works
Bitcoin operates on a public network known as a blockchain.When a transaction is confirmed, it becomes part of a block. Once added, blocks cannot be easily altered, making the system transparent and resistant to fraud.
3. What Is Bitcoin Mining?
Bitcoin transactions are verified through a process called mining. Miners use computing power to validate transactions and secure the network.
In return for their work, miners receive newly issued bitcoins. This process ensures that no single participant can control transaction history or create fake transactions.

4. Limited Supply and Scarcity
Bitcoin has a fixed supply limit of 21 million coins. This limit is enforced by the software and cannot be changed without network-wide agreement.
Unlike traditional currencies that can be printed in unlimited quantities, Bitcoin’s supply decreases over time, making it a scarce digital asset.
5. What Bitcoin Is Not
Bitcoin is often misunderstood. It is not a company, stock, or government-backed currency. It does not guarantee profits and does not eliminate financial risk.
Bitcoin should be viewed as a technology and an alternative monetary system, not as a promise of returns.
6. Why Do People Use Bitcoin?
People use Bitcoin for different reasons. Some use it for global value transfers, others for financial independence, and some for learning about decentralized systems.
Its open and permissionless nature allows anyone with internet access to participate.
