Basically, fog forms when warm air meets colder air. When this happens, water vapor in the air â a gas â is cooled enough for the gas to turn to a liquid in the form of tiny water droplets. This process is called condensation.. We see those groups of tiny droplets as clouds or, when they're close to the ground, as fog.
What is a 'Cryptocurrency'. A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Cryptocurrencies take their name from their use of cryptography. Cryptography is the study of the methods of encrypting information, primarily with the intention of sending a message securely and privately but also for tasks such as data security and authentication.
