It's just a short, catchy name or a set of letters, like a nickname, that tells you what coin you're dealing with. For instance, Bitcoin is BTC, and it's like calling your mate Dave 'Davo'—just quicker and easier when you're shouting over a noisy room, or in this case, scanning through loads of digital money info.
Example
Flipping through crypto tickers is like reading the scoreboard at a pub quiz; BTC, ETH, MEME, it’s all a jumble until you learn who’s who!
Imagine you have a box of different toy cars, and each car has a tiny name tag on it like "Red" for the red car or "Fast" for the fastest one. In the world of cryptocurrency, a ticker is like that little name tag but for digital money. It's a short way to say the name of the money, so instead of saying the whole name like "Bitcoin," you just say "BTC." It helps people quickly know which toy car—or in this case, which type of digital money—they are talking about.
Example
When I look at my collection of toy cars, I see the tags like 'Fast' and 'Big,' just like when people look at cryptocurrencies and see tickers like BTC for Bitcoin.
