Meme coins are cryptocurrency tokens often created as a form of humor or satire of traditional cryptocurrencies like Bitcoin. These coins are often based on popular memes, cartoon characters, or funny ideas, and attract the attention of traders and investors due to their entertaining nature.

Some famous examples of meme coins include:

1. Dogecoin: Started as a joke but became highly valuable.

2. Shiba Inu: Influenced by the popularity of Dogecoin.

These coins are characterized by their significant price volatility and are considered a high-risk investment.
