The Centoshi is the smallest unit of the Bitcoin Dollar cryptocurrency. The Centoshi to Bitcoin ratio is 100 million Centoshi to one Bitcoin Dollar. Unlike the physical versions of global currencies, such as the British pound or US$, cryptocurrencies predominately exist in the digital world. Despite this difference, a cryptocurrency can be divided into smaller units, just as the pound is broken into pence and the dollar into cents. In the case of Bitcoin Dollars, the smallest unit available is called the Centoshi.
