Popular understanding of digital currency

Digital currency is a decentralized, anonymous, non-tamperable digital asset that does not rely on a central bank or financial institution and uses distributed ledger technology for generation, management and transactions. Its key features include: Decentralization: managed by a distributed network. Anonymity: Often using pseudo-anonymous accounts or encryption technology. Non-tamperability: Based on blockchain technology. Transparency: All transactions are publicly recorded on the blockchain. Digital currency types include cryptocurrencies, stablecoins and central bank digital currencies. Its advantages include convenience, speed, low cost and security, while disadvantages include volatility, poor regulation, anonymity that can lead to illegal activities, and limited accessibility.

What is digital currency?

Digital currency is a digital asset that uses cryptography technology to generate, manage and trade. Unlike traditional fiat currencies, digital currencies do not rely on a central bank or financial institution, but use distributed ledger technology, such as blockchain, to record and verify transactions.

Key Features:

• Decentralization: Digital currencies are managed by a distributed network rather than a central entity.
• Anonymity: Normally, digital currency transactions use pseudo-anonymous accounts or encryption technology to protect user privacy.
• Untamperability: Blockchain technology ensures the integrity and tamper resistance of transaction records.
• Transparency: All transactions are publicly recorded on the blockchain and can be viewed by anyone.

Type:

• Cryptocurrency: Use strong cryptography to secure transactions and control issuance, like Bitcoin and Ethereum.
• Stablecoins: Aimed to anchor value to a stable asset (such as fiat currency or gold) to reduce price volatility.
• Central Bank Digital Currency (CBDC): A digital currency issued by a central bank that is designed to supplement or replace traditional fiat currencies.

Advantages:

• Convenience: Digital currencies can be easily sent and received online without being restricted by geographical location.
• Speed: Digital currency transactions are typically much faster than traditional fiat currency transactions.
• Low cost: Digital currency transaction fees are often lower compared to traditional bank transfers.
• Security: Digital currency’s encryption technology helps prevent fraud and information theft.

Cons:

• Volatility: The price of cryptocurrencies can be highly volatile, making it an unstable investment.
• Regulation: Regulation of the digital currency market is still in its early stages and regulatory changes may occur.
• Anonymity: While anonymity protects privacy, it can also be used for illegal activities.
• Accessibility: Not everyone has easy access to digital currencies, especially older or less tech-savvy people.
