A cryptocurrency is a digital or virtual currency that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralised networks based on blockchain technology—a distributed ledger enforced by a disparate network of computers. A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.
- A cryptocurrency is a form of digital asset based on a network that is distributed across a large number of computers. This decentralised structure allows them to exist outside the control of governments and central authorities.
- Experts believe that blockchain and related technology will disrupt many industries, including finance and law.
- The advantages of cryptocurrencies include cheaper and faster money transfers and decentralised systems that do not collapse at a single point of failure.
- The disadvantages of cryptocurrencies include their price volatility, high energy consumption for mining activities, and use in criminal activities.
