There is a huge HYPE around NEO. It really got out of hand and the value really does not project the current progress around the project.
It's also hard to give value to a project. You have to look at the history of several other projects to give it a rough guess. And still it might not be accurate.
I recently made a post about NEO and my concerns.

Don't take my word as trading advice. I research my coins and I think NEO right now has some red flags compared to the value.
