Bitcoin (BTC) Баасы, Анык убакыттагы баалар жана Жаңылыктар

Bitcoin is the first decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown entity 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.

Орус рублу жөнүндө

The ruble or rouble is the official currency of the Russian Federation. Banknotes and coins are issued by the Central Bank of Russia, which is Russia's monetary authority independent of all other government bodies. The ruble is the second-oldest currency in continuous use and the first decimal currency. The ruble was the currency of the Russian Empire, which was replaced by the Soviet ruble during the Soviet Union. Following the dissolution of the Soviet Union, by 1992, the Soviet ruble was replaced in the Russian Federation by the Russian ruble at par. The Russian ruble then further continued to be used in 11 post-Soviet states, forming a "ruble zone" until 1993. The ruble was further redenominated with the new ISO 4217 code "RUB, 643" just preceding the 1998 financial crisis, and was exchanged at the rate of 1000 RUR = 1 RUB. Code "RUR, 810" was then excluded from both the ISO 4217 standard and the Russian currency classifier, but continues to be used for numbering bank accounts internally within Russia. The ruble is a free-floating currency and is subdivided into 100 kopecks which have fallen out of use due to inflation. In 2023, the digital ruble was introduced. Wikipedia
