บิทคอยน์

BTC/USD
Digital coins, such as Bitcoin, can be used to pay for goods and services with vendors that accept them. They can also be exchanged for traditional currencies through a special exchange.
Issued by: System users who use their equipment’s computation capacities to maintain the system’s operation (mining). Issuance is decentralised and limited by volume (21 million units) and time.
Bitcoin’s price dynamics are based on confidence and are formed solely by supply and demand. The system doesn’t have a central body to control the issuance, influence the rate and acceptance or make others accept payments in Bitcoin. That’s why the actual value of Bitcoin depends on the dynamics of the global volume of goods and services one can buy.
