Why should it be a Ponzi scheme? Sorry, but I don't get it...

Do your own research....the OP is trying to claim that the founder kept all the pre-owned ICO tokens for himself....He's obviously new to crytocurrency and thinks that everybody is as naive as him ---> He hasn't taken the time to look up the term intitial coin offering (ICO) and still thinks money comes from thin air....He may learn if he figures out how to listen, but if he hasn't taken the the time to check his own version of the facts yet, then he may just continue doing himself, and others, an extreme disservice....---> because some of us are making a lot of money by understanding the REAL facts.

Except no one would take that serious if it has zero volume. You can see the market cap and daily volume on coinmarketcap. You can also see things like circulating supply and total supply. The real valuation is not as simple as taking one or two metrics, you need to take everything into account and ethereum has and is doing well in this regard.
