What is cryptocurrency and how is it used

Cryptocurrency. Definition and description

Cryptocurrency is any kind of currency in digital or virtual form; To protect transactions in cryptocurrency, encryption (cryptography) is used. There is no central authority to issue or regulate cryptocurrencies. A decentralized system is used to record transactions and issue new units.

What is a cryptocurrency?

Cryptocurrency is a digital payment system that does not involve banks in verifying transactions. It is a peer-to-peer system that allows anyone, anywhere, to send and receive payments. Cryptocurrency payments exist exclusively digitally in an online database describing specific transactions. They do not imply transactions with physical money that have circulation and the possibility of exchange exchange in the real world. When transferring funds in cryptocurrency, transactions are recorded in a public ledger. Cryptocurrency is stored in digital wallets.

The term Cryptocurrency came into use due to the fact that encryption (cryptography) is used to verify transactions: advanced encryption is used to store and transfer cryptocurrency data between wallets and to public registries. The purpose of encryption is to provide reliability and security.

The first cryptocurrency was bitcoin, created in 2009 and the most famous to date. Cryptocurrency trading is interesting in terms of making a profit; as a result of speculative activities, price jumps for cryptocurrencies are periodically observed.

How is cryptocurrency applied?

Cryptocurrencies are processed in a distributed public registry – a blockchain, where records of all transactions are stored, updated by currency holders.

Cryptocurrency units (coins) are created during the mining process. This is a process in which the computing power of a computer is used to solve complex mathematical problems, as a result of which coins are generated. Users can also buy currency from brokers and then store and spend it using cryptographic wallets.

Cryptocurrency is not a material object, it is a key that allows you to move a record or unit of measure from one person to another without a trusted third party.

Bitcoin has been around since 2009, but financially, cryptocurrencies and the application of blockchain technology are still in their infancy; their rapid development is expected in the future. In the future, cryptocurrencies can be used in trading transactions with stocks, bonds and other financial assets.
