Guys we are talking a lot of times about "this project is scam" or "this project is amazing and soon moon" but sometimes scam project making a lot of x but amazing project making -90%. So what is for you good project? Which team and project is fake but making xx or team and project real but price making -90% and we should hold?
I cannot give you a specific coin but I can say a thing or two about your other question. A scam project is a project that has a fake team, fake or copied whitepaper, fake or copied vision/objective, fake roadmap, or fake or copied design generally. A scam project could also be used to refer to those projects that raised money and leave after that. It could also refer to projects that do not honor words of agreement. A good project is of course the opposite of all those.
Adding to that is they are completely copying concepts and gives some updates to existing project attracting investors that they are much better usages from another coin who already gained support from the public. Scam developers are not going to invest time working with their projects but focus with how they can convinced people to invest money and runaway after. There's no easy task finding this team but if you are concern with your money you will extend your research to avoid or lessen your chance being victimized.
