Projects ko Judge karna ek bahut mushkil kaam hai aur youtube Channel se agar proper guidance nahi di ja rahi to koi faida nahi. Scam karna hi agar purpose ban jaye to phir chori karke kamao ya dakaiti se baat ek hi hai.
Ye to ek dum sahi baat hai. If you want to know a project better than my advise is to read it's white paper. After reading it if you think it worthy of your investment then go ahead. Still there is no guarantee whether that project will work or ditch you in the future. Blindly never follow any influencers. There are a lot of example of influencers recommending project which later on became a scam.
