Bitcoin (BTC) Price, Real-time Quote & News

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

About Iranian Rial

The rial is the official currency of Iran. It is subdivided into 100 dinars, but due to the rial's low purchasing power the dinar is not practically used. While POS terminals are in use in Iran, the country does not participate in any of the major international card networks due to sanctions between it and the United States. Travelers are instead advised to load money onto a local prepaid card account. There is no official symbol for the currency but the Iranian standard ISIRI 820 defined a symbol for use on typewriters and the two Iranian standards ISIRI 2900 and ISIRI 3342 define a character code to be used for it. The Unicode Standard has a compatibility character defined U+FDFC ﷼ RIAL SIGN. A proposal has been agreed to by the Iranian Parliament to drop one zero at the end of number, by replacing the rial with a new currency called the toman, the name of a previous Iranian currency, at the rate of 1,000 toman = 10,000 rials.
