Just noticed a lot of newcomers asking about what these abbreviations mean on exchanges, so figured I'd break it down real quick.

Basically, when you're looking at charts or volume numbers, you'll see these letters thrown around constantly. 1 k means 1000, which is probably the most common one you'll encounter. Then it scales up from there pretty quickly.

1M is 1 million, which you'll see when talking about larger trading volumes or market caps. 1E represents 100 million, though honestly this one gets used less frequently in my experience. 1B is 1 billion, and once you start seeing numbers in the billions, you know we're talking about some serious liquidity or market movement.

At the top end, 1T equals 1 trillion. You mostly see this when discussing total market cap or when Bitcoin is making big moves in terms of overall value.

The reason exchanges use these abbreviations is pretty straightforward - it keeps the numbers readable instead of staring at a screen full of zeros. Once you get used to it, reading 5.2B volume is way easier than trying to parse 5,200,000,000. Definitely worth memorizing these if you're planning to spend any real time trading on any major platform.
