Many cryptocurrency newcomers often see markings like 1K, 1M, 1B, 1E, 1T on exchanges but don't know what 1K means. Actually, these are all internationally standard counting units: 1K represents 1000 (one thousand), which is easier to understand if you think of it in terms of currency. 1M equals 1 million, 1B equals 1 billion, 1E equals 100 million, and 1T represents 1 trillion. On exchanges, these units are typically used to indicate total market capitalization, trading volume, or token supply. Understanding this counting system can help you quickly read market data.
