What Is a Coin?

Coin is a free mobile app that rewards users with digital assets for simply using their phone’s GPS to verify their location. The app is available on both iOS and Android and has been downloaded over a million times. The earnings users earn through Coin can be used to purchase a variety of digital and physical products, such as Bluetooth speakers. Coin has partnered with the XYO Foundation to ensure that its software can verify a user’s existence in their claimed location. This helps to prevent “location spoofing”, where users fake their location in order to earn more Coins.

A coin is a small piece of hard material, usually metal, in the shape of a disc, and issued by a government to be used as money in transactions. The value of a coin derives from the material it is made of, its history as currency, and its design. Coins are typically used for lower-valued units, while banknotes are used for higher values in most money systems. Coins are typically smaller than paper bills and have a fixed, standardized weight. They can be minted in large quantities and are often issued in multiple denominations.

The most commonly traded coins are precious metals, such as gold and silver. However, coins can also be made of non-precious metals such as copper or zinc. They may be stamped with images, numerals or text. Traditionally, the side of a coin bearing a bust of a monarch or other important person, or a national emblem, is known as the obverse, and the reverse is known as heads. A coin whose sides are identical is usually called a flat-sided coin, but bi-metallic coins such as the Canadian two-dollar toonie and Somalia’s guitar-shaped 10 zloty coin have also been used.

Coins are usually circular in shape, but some are shaped to resemble other objects, such as farming implements or weapons. Historically, coins have been standardized in size and weight and made to be easily exchanged for other goods or services. Their use as money became widespread around three thousand years ago, when the Lydian king Croesus introduced a silver coin called a croesid. Other forms of money were in use at the time, including cowrie shells from Africa and fei stones from Micronesia, but coins were more durable and portable than the aforementioned items. Coins also facilitated trade because they were more reliable than rumor or written promises.

The COIN framework enables people to discuss difficult topics and provide feedback in an effective way, and it is often used by business leaders in coaching their staff. The process starts with context: explaining the background and circumstances of the issue you want to discuss. It then moves on to observations, which are specific details of what happened. Finally, it outlines impact — the positive and negative effects on others in the team or organization. The aim is to encourage open and honest discussions that lead to positive, long-lasting change.
