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.

Повеќе за Полска злота

The złoty is the official currency and legal tender of Poland. It is subdivided into 100 groszy. It is the most-traded currency in Central and Eastern Europe and ranks 21st most-traded in the foreign exchange market. The word złoty is a masculine form of the Polish adjective 'golden', which closely relates with its name to the guilder, whereas the grosz subunit is based on the groschen, cognate to the English word groat. It was officially introduced to replace its interim predecessor, the Polish marka, on 28 February 1919 and began circulation in 1924. The only bodies permitted to manufacture or mint złoty coins and banknotes are the Polska Wytwórnia Papierów Wartościowych, founded in Warsaw on 25 January 1919, and Mennica Polska, founded in Warsaw on 10 February 1766. As a result of inflation in the early 1990s, the currency underwent redenomination. Thus, on 1 January 1995, 10,000 old złoty became one new złoty. As a member of the European Union, Poland is obliged to adopt the euro when all specific conditions are met; however, there is no time limit for fulfilling all of them. Currently, Poland is not in the European Exchange Rate Mechanism. Wikipedia
