KOL

A KOL, or key opinion leader, is a crypto account with a large following on X, Telegram or YouTube whose post can lift a small token's price within minutes. Callers, channels that post token addresses “to buy”, belong to the same group.

Many KOLs earn money from promotion. Token creators pay them in cash or with a token allocation, often before the public launch, and such posts rarely carry a clear ad label. The typical pattern goes like this: the KOL buys early or receives tokens, posts something enthusiastic, followers buy, and the KOL sells into their buying. On-chain analysts regularly expose promoter wallets that sell right after a post.
