A hard coin fork is one of the ways to develop and improve cryptocurrency. However, in practice, the separation of one coin from another occurs for various reasons, although it is always claimed that this is done to improve the functionality of the coin. The price of the separated coin depends on how much the society perceives the need for a plug, as well as what tasks are solved and how much they are in demand. Many forks are held, and then almost nothing is heard about the created coins and they do not play any role. Users of a coin, from which another is separated, usually have a positive attitude towards holding a hard fork, since it is always an opportunity to get a certain amount of new coins for free.
