one of the problems is that they do take different form each time they come. now there are high APYs just like ponzi and very many people are doing it. so it wont stop as long as people keep patronizing them. its all about first in and first out. people need to get more wiser.
They will follow every hype for the opportunity to deceive many investors, now many potential scam APY projects are in the list of new projects but I really wonder, why investors don't get tired of being caught in the scam circle. They must be wise before deciding to invest in the wrong project.
