Meme coin
In short A meme coin is a token driven mainly by an internet joke, mascot, or community culture rather than by a product or cash flow.
A meme coin is a cryptocurrency whose main draw is a meme, a mascot, a joke, or a community identity, not a working product. Dogecoin, created in 2013 as a parody, is the original example, and dog, cat, and frog themed tokens have followed ever since. Most meme coins openly say they have no utility.
Technically, a meme coin is usually an ordinary token: an ERC-20 on Ethereum or Base, a BEP-20 on BNB Chain, or an SPL token on Solana. Creating one takes minutes, and launch platforms on several chains let anyone deploy a token and its trading pool for a small fee. Price comes almost entirely from attention, so social media, influencer posts, exchange listings, and community activity drive the chart.
Meme coins matter because they make up a huge share of new tokens and of the trading on decentralized exchanges. Moves of 10x up or 90 percent down within days are common. A few become widely held, but most lose nearly all their value, and the category attracts rug pulls, pump and dump schemes, and insiders who bought at launch and sell into the hype.
If you trade them, check the boring details first. Look at holder concentration and whether the deployer or a cluster of linked wallets holds a large share. Check that liquidity is locked or burned, that the contract has no mint, blacklist, or adjustable tax functions, and that ownership is renounced. Be wary of paid promotion and sudden coordinated hype. Size positions as money you can afford to lose completely.
