That's a good point of view and I fully share it. But you know it's very hard sometimes to determine whether the project is a scam or not. During these last few years scammers have learnt how to act and what to do in order to deceive even professional investors. Let alone the newbies...That's why we need to get experience and skill to avoid such scam stories and leave them behind.
there are still a lot of people who don't know what cryptocurrency is or how to use it and they are the main target of those scammers who have been a virus in this space. it will take some time for the mass adoption but hopefully all scammers has been caught by that time.
