I checked Zeux and the volume is all faked, i think i am wasting my time if i take a look the other ones because those are not in any trusted exchanges either.
You're probably correct about that. I don't know anything about any of these projects and have never even heard of them, but the fact is that most of them are scams and even if they aren't, the project is usually trying to impose a blockchain solution on a problem that doesn't need it.
Op, you say there's good trading volume on the tokens, but that may not last forever. I'm not sure when the tokens were released for each project, but I can almost guarantee you that interest won't last in them, and if that happens they'll get delisted from whatever exchanges currently list them. Beware.
