Hey. I heard from some in this forum that iota is scam. while their team and research process are so active. Programmers are active in github. the discord forum of this coin is very active and various. the whitepaper and roadmap is obvious and it is trying to reach them. it is presents a new technology.
There is a lot levels of scam. Biggest is when someone makes ICO and takes money and vanish. That is scam for all. Then second level is that someone make ICO collect money and have a huge plan that he is simply not able to deliver. HE pay himself nice salary. Employ some more people and slowly spend all money that was collected in the ICO. For that not everyone can say is a scam. Even police and court will have problems with it, But investors the same way end up empty handed.
