Nah, he sounds legit.
Can you tell by the tone of his voice, and the look in his eyes?

He might be legit, of course. There has to be some in the top 10 that aren't lying.
We know that the first 3 are not lying.
About him - I can tell by the way he wrote his last few posts. Just didn't sound like a moonkid.
Edit: not that it matters that much..
It matters A LOT! Lies make baby Jesus cry.
P.S. - I am in the top 10 ETH holders.
