When it comes to money people like trying out things the way they see fit, try first learn later is the rules of newbies and thats why they always get scammed easily, HYIP, Pyramid Scheme, as dangerous and alarming these two are people still join them till date, both crypto and internet is not the evil here, people are to be blame for what happened to them
Newbies don't really take time in studying how any many things on the internet work especially HYIPs and most often they are very greedy and gullible are easily carried away by juicy offers of course most of them wanted to make quick money thus get scammed and even when warned not to fall for those internet pranks they ignored those warning until they get scammed before realizing their mistakes.
I agree with your point, from some of the reviews that you tell me it is indeed the fact that many beginners are tempted by the sweet promises offered by the project which turned out to be a scam. lack of knowledge and greed is one of the factors why someone easily gets scammed.
