Well what percentage of crypto people not greedy? if they were looking for good projects the good projects would dominate. .the good useful projects do not dominate the space. coins that appreciate and are pumped dominate the space or can be manipulated. that's why defi does so well it's based on pumped coins not utilized coins.. that doesn't mean it wont change in the future it will.. but right now thats mostly what's going on. so most people know the projects are already scams or not they participate anyway
