Coin Currency
Coin currency is a type of money made from metals or an alloy. It is a type of fiat money, meaning it has value only because it is backed by a government’s promise to pay. It is generally used in conjunction with paper money to make transactions. In ancient times, coins were often minted from precious metals, but these days most countries use base metals such as copper and nickel. In the past, precious metal-based coins incurred high costs and were susceptible to manipulations such as clipping (cutting off small amounts of metal from a coin), which reduced their intrinsic value. These problems led many monarchs to reduce the amount of precious metal in circulating coins, a process called debasement.
Modern coins are usually minted from copper or a mixture of metals such as aluminium, zinc, and nickel, and some also have trace amounts of silver. They are pressed into the desired shape from large sheets of metal rolled into coils. The coins are then struck against a die to create the desired design. Most modern coins are round, but some are shaped like polygons, have wavy edges, or have holes in them. The holes in some coins allow them to be strung on cords for carrying or storage. They may also help distinguish different types of coins of the same type and size.
Historically, the most valuable coins were those made of precious metals. However, it was often difficult to produce enough of these coins to meet demand. Therefore, some monarchs decided to debase their coins by replacing a fraction of the precious metal content with cheaper base metals such as copper and nickel. This process reduced the intrinsic value of each coin but allowed for a greater volume of coinage to be produced.
A few rare, antique and collectable coins are made of precious metals such as gold and silver. Most collectors do not acquire coins based on their intrinsic value, but rather for their historical or aesthetic value. They are often stored in coin albums or other containers, which should be acid-free and free of polyvinyl chloride. Some coin collections are kept in safe deposit boxes at banks.
Cryptocurrency and terrorism:
Illicit activities using cryptocurrency have increased in recent years, with cybercriminals deploying ransomware attacks to take control of computers and then demanding payment in virtual currency; terrorists and drug cartels also increasingly use cryptocurrencies. The rise of these illicit uses has motivated governments to enhance their efforts at enforcement, such as by shutting down sites that facilitate the trading of cryptocurrency on the darknet. These sites can be used to buy and sell a variety of illegal goods and services, including narcotics, weapons, and ammunition, as well as for money laundering and financing terrorism.
