All those ran with investments though, PBMining has not. I'd also guess they've reached their investment peak long time ago ( the point where it'd be the most profitable to run with the investments ).
You could be right but I don't think there is any way to know when they will/have peaked.
Look at the "sent" chart:

Anyways for every reason that they might be legit, there are a dozen reasons they are probably not.
Again, PBmining could dispel all rumors/doubt by simply providing a mining address. Why don't they?
We've been reading your red flags for pages already, everyone got your point mate. But the truth is, those who care are gone and those who don't, well they enjoy while it lasts. Just stop filling the board with useless talks and increasing your post counts.
