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. If just enough light wind is present â a couple of mph, at most â this chilled air can be gently stirred through a deeper layer, forming a deeper radiation fog.
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 widely regarded as the first modern cryptocurrency â the first publicly used means of exchange to combine decentralized control, user anonymity, record-keeping via a block chain, and built-in scarcity. It was first outlined in a 2008 white paper published by Satoshi Nakamoto, a pseudonymous person or group.
