There are several criteria that may indicate an ICO (Initial Coin Offering) is "bad" or potentially fraudulent. These may include:
Lack of transparency or unclear project goals
Plagiarized or unoriginal whitepaper
Unrealistic or exaggerated claims about potential returns or benefits
Lack of a strong development team or credible advisors
Poor communication with investors or failure to meet project milestones
Lack of a working prototype or MVP (Minimum Viable Product)
Negative reviews or reports from reputable sources.
It's important for investors to thoroughly research any ICO before investing, and to be cautious of any projects that exhibit these or other concerning red flags.
