Based on recent warnings and sentiment in the cryptocurrency space, here are three coins or projects that have been flagged as potential flops or scams in 2025:

TCG3 - Posts on X have repeatedly highlighted TCG3 as a project to watch out for, citing manipulated testimonials and fake team members as red flags.

AlphinHorizons - Similarly, AlphinHorizons has been called out on X for deceptive practices, including the use of fabricated endorsements, raising concerns about its legitimacy.

Linayrex - This project has also been mentioned alongside TCG3 and AlphinHorizons in X posts, with warnings about unverifiable claims and potential fraudulent activity.

These concerns stem from posts on X and align with broader warnings from sources like the North American Securities Administrators Association (NASAA), which noted in March 2025 that crypto scams are becoming more sophisticated, often involving fake tokens and manipulated information. However, this information is not conclusive, and you should verify the legitimacy of any project independently before investing. Always conduct thorough research and be cautious of projects with unverifiable claims or suspicious practices.
