I'm not an expert by any means but from a wallstreet point of view - when you see "insiders" accumulating stock it's often a green flag as a buying signal. The fact that those who hold the top % are already heavily financially invested yet they continue to invest more money into the company (or in this case, the software/idea/coin) it typically means there are good things to come. Usually the top % holders have the first take at inside information - I.E they know whether good things or bad things are in the foreseeable future.

So the point being - if you see top Vericoin holders buying more Vericoin, that means they are confident it's going to go up in value. Visa versa if you see top coin holders selling out - it's usually a sign that they know things are falling apart. It's not 100% always that way but it's probably a 60/40 or 70/30 to be true.
