Recently, some friends asked me what those letters and numbers in exchanges mean. I found that many beginners actually don’t quite understand this counting system. Today, I’ll clarify it.

The counting units used on exchanges are simply a way to simplify large numbers. For example, 1K stands for 1k, which most people know. Going higher, 1M means 1 million. If you see a coin’s market cap as 1M, that indicates a value of 1 million USD. Even larger, 1E represents 100 million, 1B is 1 billion, and 1T is 1 trillion.

Let me give you an example: if a project’s trading volume is a little over 1 million, it might be displayed as 1M+. If a blockchain’s total market cap reaches 10 billion, it will be marked as 10B. This system is especially convenient when viewing charts, as you don’t have to count a long string of zeros.

Especially during quick scans, being able to instantly recognize the scale is very important. The units 1K, 1M, 1E, 1B, and 1T cover about 99% of data annotations on exchanges. Once you get used to it, you can quickly judge the size of a project or trading pair, which helps with trading decisions.
