Bei ya Bitcoin (BTC), Orodha ya Bei za Moja kwa Moja na Habari

Sarafu ya Bit ni mfumo wa malipo dijitali ambao unatumiwa na mamilioni ya watu bila msimamizi wa juu kama Benki Kuu ilivyo katika nchi mbalimbali. Sarafu hiyo huweza kutumika kwa kubadilishana na sarafu nyingine, bidhaa au huduma. Sarafu ya Bit ilianzishwa na mtu asiyejulikana au kikundi cha watu chini ya jina la Satoshi Nakamoto na kutolewa kama programu huria mwaka 2009. Kuanzia Februari 2015, wafanyabiashara zaidi ya 100,000 wanakubali Sarafu ya Bit kama malipo. Kwa mujibu wa utafiti wa Chuo Kikuu cha Cambridge wa mwaka 2017, kuna watu kati ya milioni 2.9 hadi 5.8 wanaotumia malipo dijitali na wengi wao wanatumia sarafu ya bit. Mara nyingi sarafu ya bit inaitwa "pesa ya dijitali" lakini wataalamu wengi huiona si pesa bali bidhaa ya bahatisho. Paul Krugmann pamoja na wapokeaji wengine wa Tuzo ya Nobel ya Elimu ya Uchumi aliita udanganyifu akiilinganisha na bahatisho la vitunguu vya maua ya tulip huko Uholanzi katika karne ya 17. Wikipedia

Kuhusu Ruble ya Urusi

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
