Excellent thread. I would say that some of the red flags are more like "yellow" or "orange" flags if you know what I mean. A red flag IMO is something that is a deal breaker. Just to mention some red bright red flags:

- Team´s Linkedin profiles with no contacts or with contacts that once you dig a little bit, don´t look real.
- Lately, as seen on Dencity, some of the advisers deny involvement in the project, yet they are listed.
- There are obvious technical flaws that make the project impossible or very difficult. Not just barriers to overcome, but things that are really impossible. For example, if a network is frequently overloaded, it is unlikely that you will be able to make instant payments with low fees.
- Unrealistic market caps, no soft or hard cap.

I think my point is clear. There are Bright Reds and things that need to be addressed.
