Some Common Types of Fog. The most common form of fog, known as radiation fog, typically occurs on clear nights as the earth's surface cools moist air immediately above it.

A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency.
Bitcoin is the preeminent cryptocurrency and first to be used widely. However, hundreds of cryptocurrencies exist, and more spring into being every month. Cryptocurrencies use cryptographic protocols, or extremely complex code systems that encrypt sensitive data transfers, to secure their units of exchange.
