What's the most deadly sin a project can commit?

Let's be honest, we are dealing with a very speculative market with alot of biased towards projects, so what turns you off in a project? This has become increasingly interesting to me as there are alot of projects that are deemed tainted by certain events. I am personally am a big bull for DERC, but due to alex becker having association I have heard alot of the people stating the project is a "scam". Personally after investing and researching in the team I am grateful for the current prices, but what drives price? I want to hear the meme coin stories, underated projects that are being subjected to bad media, and what caused you guys to pivot from your most trusted projects? I have held alot of different crypto, and made alot of these choices myself, what feeds your brain? Hope you all engage, I think this could be a great topic!!
