It's usually the team behind the coin that makes something valuable. The coin itself doesn't matter but what matters is mostly what it represents. What it have to represent is an idea that will have real impact in the future. There are so many projects out there that are doing exactly that, they are not offering anything substantial or of value to future customers. They are jus tlooking to make a quick profit in the booming market and many of them manage to do so, which attracts other people to do just the same. It's a never ending circle which is why we see so many horrible and useless coins circulating. At some point they will all collapse and only the strong coins will remain. These will always be the one's that had a vision and actually impemented steps in order to realize it.
