Shilling refers to the practice of promoting or endorsing a product, service, or cryptocurrency, often for personal gain, without disclosing that the promoter has a financial interest in it. This can occur in various online platforms, including social media and forums, where individuals may create fake accounts or use their influence to mislead others into buying or investing. The term is commonly associated with the cryptocurrency space, where some influencers may receive compensation in the form of tokens or money to promote specific projects. This can lead to misinformation and potential financial loss for unsuspecting investors who trust these endorsements.
