Cryptocurrency bubble

A cryptocurrency bubble is when the price of a certain cryptocurrency (a type of digital money) goes up very quickly. This often happens when people get really excited about something and try to buy it quickly. Think of it like a really big party — when lots of people want to go, the price of getting in gets really expensive. This can happen with bitcoin or other types of digital currency, which can make the price go up and down really fast. Eventually, the bubble bursts, or the price goes down, and lots of people lose money.
