Many beginners get confused by these letters when checking market data on exchanges. Today, I’ll walk you through the most common counting units used on exchanges.

First is K—this one is the simplest. 1K means 1,000. If a coin’s price is 2.5K, that means 2,500 dollars.

Next is M. People often ask how much 1M is. Actually, 1M equals 1,000,000—that’s the “million” level. If a project’s market cap is displayed as 5M, that means 5,000,000 dollars. In an exchange’s trading volume or open positions, the unit M shows up especially often.

E represents 100 million. This unit is used more frequently when discussing large fund flows. For example, if a certain address transfers in 3E of a coin, that means 300,000,000 coins.

B means 1 billion. It’s usually used for projects with particularly large market caps. For some major coins, their daily trading volume can easily reach several billions (B) at a time.

Finally, T represents trillions—the largest unit. When Bitcoin’s total market cap breaks through 1T dollars, this unit is used to express it.

Once you’ve got these units down, reading market data becomes a lot clearer. The next time you see these letters, you’ll be able to quickly figure out exactly how much it refers to.
