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.
A brief attempt at explaining the madness of cryptocurrency. Cryptocurrency may as well be called cryptic currency, because it's nowhere near as easy to figure out as typical money. For one, while most of them (and yes, there's more than one) have names that end with -coin, they don't usually come in physical form.
