What Is Bitcoin?
Bitcoin is a decentralized digital currency that allows people to send and receive money over the internet without relying on a central authority like a bank.
Launched in 2009 by an anonymous creator known as Satoshi Nakamoto, it operates on blockchain technology, which records every transaction in a secure, transparent, and immutable way.
Bitcoin is often seen as a store of value, like digital gold, and is used for everything from peer-to-peer transfers to long-term investment. Its limited supply—capped at 21 million coins—helps drive its value and appeal.
How Does Bitcoin Work?
Bitcoin relies on a decentralized system and cryptographic technology to enable secure, peer-to-peer transactions without intermediaries.

Limited Supply and Halving
Bitcoin has a capped supply of 21 million coins, which increases its scarcity and appeal.
Predictable Issuance: New bitcoins are introduced at a fixed rate through mining.
Halving Events: Every four years, the mining reward is cut in half, slowing supply growth.
Inflation Resistance: Unlike fiat currencies, Bitcoin cannot be printed or inflated by governments.
This scarcity model positions Bitcoin as a hedge against inflation and a long-term store of value, drawing comparisons to precious metals like gold.
Feature | Bitcoin (BTC) | Ethereum (ETH) | Litecoin (LTC) |
|---|---|---|---|
Max Supply | 21 million | No max cap | 84 million |
Inflation Rate | Deflationary (halving every ~4 yrs) | Currently inflationary (switching to deflationary under ETH 2.0) | Deflationary |
Primary Use Case | Store of value, digital gold | Smart contracts, DeFi, NFTs | Cheaper/faster Bitcoin alternative |
Halving Mechanism | Every 210,000 blocks | Not applicable | Every 840,000 blocks |

Blockchain Ledger System
Bitcoin operates on a public ledger known as the blockchain, which records every transaction in chronological order.
Immutable Records: Once a transaction is recorded on the blockchain, it cannot be changed or deleted.
Transparency: Anyone can view the blockchain, ensuring transparency and accountability.
Decentralized Nodes: Thousands of nodes maintain the ledger, helping to prevent fraud or tampering.
Because of this system, users can trust that the history of each Bitcoin is authentic and unaltered, reducing the risk of double-spending.
-
Mining and Proof of Work
Bitcoin transactions are verified through a process called mining, which uses computational power to solve complex mathematical problems.
Incentivized Mining: Miners receive newly minted bitcoins and transaction fees for validating blocks.
Security through Difficulty: The computational challenge helps secure the network from attacks.
Decentralized Participation: Anyone with the right hardware can become a miner and help maintain the network.
This system makes Bitcoin secure and resistant to manipulation because it would require immense resources to alter past transactions.
-
Private Keys and Wallets
Users store and access their Bitcoin using digital wallets secured by cryptographic private keys.
Ownership via Keys: Your private key gives you control over your Bitcoin.
Wallet Types: Wallets can be software-based (mobile apps, desktop) or hardware-based (cold storage).
Irreversibility: Losing your private key means permanently losing access to your Bitcoin.
Therefore, securely managing your private keys is essential for keeping your assets safe, especially since Bitcoin transactions are irreversible.
Platform | Supported Coins | Swap Fee | MetaMask Wallet | +16 | 0.875% |
|---|---|---|
Coinbase Wallet | +3,000 | 1% |
Trust Wallet | +5,000 | 0%
Users still need to pay blockchain network fees (gas fees) and potential liquidity provider fees when swapping assets |
Ledger Hardware Wallet | +5,000 | About 0.25%
The Swap service is facilitated by third-party providers such as Changelly and ParaSwap, each with their own fee structures. For instance, Changelly charges a transaction fee of approximately 0.25%. |
Exodus Wallet | +300 | 0%
Users still need to pay blockchain network fees (gas fees) and potential liquidity provider fees when swapping assets |
Crypto.com OnChain | +1,000 | 0.3% |

Peer-to-Peer Transactions
Bitcoin allows users to send money directly to one another without intermediaries like banks or payment processors.
Fast Transfers: Transactions are processed in minutes, regardless of location.
Low Fees: Especially for international payments, fees are often lower than traditional banking systems.
Borderless Payments: Anyone with internet access can use Bitcoin, promoting financial inclusion.
As a result, Bitcoin is particularly popular in countries with unstable currencies or restricted banking access.
Bitcoin Benefits & Risks: What Investors Should Know
Bitcoin can be a powerful investment, but it comes with both potential rewards and real risks that every investor should understand.
Benefits | Risks |
|---|---|
Store Of Value | Volatility |
Decentralization & Control | Regulatory Uncertainty |
Borderless Transactions | Cybersecurity Threats |
Growing Adoption | Loss Of Access |
Portfolio Diversification | Lack Of Consumer Protections |
- Store of Value
Bitcoin’s limited supply and deflationary model make it appealing as a long-term hedge against inflation—much like digital gold.
- Decentralization and Control
Because Bitcoin is not controlled by any government or central bank, users retain full control of their funds at all times.
- Borderless Transactions
Bitcoin allows fast, low-cost international transfers, making it useful for global remittances or sending funds across borders without banks
- Growing Adoption
Bitcoin is gaining mainstream acceptance from companies, financial institutions, and even some governments, which may increase demand and price.
- Portfolio Diversification
Including Bitcoin in a broader portfolio can reduce exposure to traditional financial markets, offering a new kind of uncorrelated asset.
- Volatility
Bitcoin’s price can swing wildly within hours, making it difficult for conservative investors to manage risk or time the market.
- Regulatory Uncertainty
As governments around the world explore crypto regulations, changes in law could impact Bitcoin's price or even restrict access.
- Cybersecurity Threats
While blockchain itself is secure, exchanges and wallets can be hacked, putting investor funds at risk without strong precautions.
- Loss of Access
If users misplace private keys or recovery phrases, their Bitcoin is irretrievably lost—with no support line to call.
- Lack of Consumer Protections
Unlike credit cards or banks, there’s no way to reverse transactions or recover funds if something goes wrong.

You can buy as little as one satoshi, which is one hundred millionth of a Bitcoin. Many platforms allow fractional purchases.
Once all coins are mined, miners will be incentivized solely through transaction fees, ensuring the network remains functional.
