Personally, I don't think they are lazy. In fact, many of them work hard and create new technologies. Unfortunately, their efforts are aimed at fraud and dishonest income. I very much hope that in the future the situation will change and they will be engaged in honest, useful work.
Scammers have no excuse. They all direct their thoughts to stealing money from ordinary people. They harm not only by stealing, but also by undermining people's trust in investing in ICO, and they stop investing even in good ICO.
