Cryptocurrency is a digital currency designed for secure online transactions, leveraging blockchain technology to record transactions transparently and immutably. Unlike traditional currencies, cryptocurrencies are decentralized, meaning they aren't controlled by any single entity like a central bank. This ensures security and makes counterfeiting nearly impossible.
What Is Blockchain?
Blockchain acts as a digital ledger for transactions, built using cryptography, computer networks, and electricity. Each verified entry is permanent and publicly stored—no one can alter or delete records without disrupting the chain. Modifying any data would break the blockchain's integrity.
Key Features of Blockchain:
- Immutability: Records cannot be changed retroactively.
- Decentralization: No central authority controls the data.
- Transparency: All transactions are visible on a public ledger.
Advantages of Cryptocurrency
- Anonymity: Transactions are pseudonymous, appealing to users prioritizing privacy.
- Transparency: While identities are hidden, transaction details are publicly verifiable via blockchain.
- Decentralization: Free from government interference or monetary policies.
- Profit Potential: High volatility can lead to rapid gains. For example, Bitcoin has seen daily surges exceeding 200%.

Disadvantages of Cryptocurrency
- Price Volatility: Values can plummet as quickly as they rise. Bitcoin dropped 50% in two months (April–June 2021) after a 100% surge earlier that year.
- High Production Costs: Mining consumes vast resources. Bitcoin alone uses 110 TWh annually—0.55% of global electricity, equivalent to small nations like Malaysia.
- Regulatory Risks: Lack of central oversight increases investment risks. Most governments haven’t fully regulated cryptocurrencies.
- Loss of Access: Losing private keys or hardware failures can permanently erase tokens, with no recovery options.
