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.
Every cryptocurrency holder has a private key that authenticates their identity and allows them to exchange units. Users can make up their own private keys, which are formatted as whole numbers between 1 and 78 digits long, or use a random number generator to create one.
