Shill or shilling is a crypto slang for promoting an crypto token or coin for your own benefit. A person who does the shilling can be called a shiller. Shillers want to draw attention to a cryptocurrency in hopes of raising demand and ultimately driving up the price of the digital asset.
Note: shillers are only motivated by the fact that they can profit from it. Shillers pump up a project through social media, their bag of the project cryptocurrency increases in value due to the increased interest they helped drum up, and they sell a large part of their holdings for a profit. So before you invest, be careful and DYOR first.
