Bitcoin (BTC) цена, квота во реално време и вести

Bitcoin is the first decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown person published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. From 2021 to 2025, El Salvador adopted it as legal tender currency before revoking it. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries. Bitcoin works through the collaboration of computers, each of which acts as a node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of transactions, called a blockchain, without central oversight. Transactions are validated through the use of cryptography, preventing one person from spending another person's bitcoin, as long as the owner of the bitcoin keeps certain sensitive data secret. Consensus between nodes about the content of the blockchain is achieved using a computationally intensive process based on proof of work, called mining, which is performed by purpose-built computers.

The Central African CFA franc is the currency used in six independent states in Central Africa: Cameroon, the Central African Republic, Chad, the Republic of the Congo, Equatorial Guinea and Gabon. These six countries had a combined population of 55.2 million in 2020, and their total GDP exceeded US$100 billion. CFA originally stood for Colonies françaises d'Afrique; after these states gained independence, its name was changed to Communauté financière africaine. The currency is issued by the Bank of Central African States, located in Yaoundé, Cameroon, for members of the Economic and Monetary Community of Central Africa. Although the franc is officially divided into 100 centimes, no centime-denominated coins have been issued. Since 1945, the Bank of France has been producing CFA franc notes in Chamalières. In several west African states, the West African CFA franc, which is of equal value, is also in circulation. Wikipedia
