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

Bitcoin is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that secures the bitcoin blockchain. Mining consumes large quantities of electricity and has been criticized for its environmental impact. Based on a free market ideology, bitcoin was invented in 2008 by Satoshi Nakamoto, an unknown person. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. In 2021, El Salvador adopted it as legal tender. It is mostly seen as an investment and has been described by many scholars as an economic bubble. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries as of 2021. Wikipedia

The koruna, or crown, has been the currency of the Czech Republic since 1993. The koruna is one of the European Union's eight currencies, and the Czech Republic is legally bound to adopt the euro in the future. The official name in Czech is koruna česká. The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value or sometimes before it. One crown is made up of 100 hellers, but hellers have now been withdrawn from circulation, and the smallest unit of physical currency is 1 Kč. Wikipedia
