I think Eth made the biggest ever mistake by going to pos from pow. The more we look at pow, the more uses we see for it, even fixing the environmental problems, and lately with hydrogen fueled backup technology coupled with solar, we can even see proof of the value of proof of work tokens, because they are physically exchangeable at time of creation with hydrogen fuel, no-one can claim they are a Ponzi any longer.
The same does not apply to Eth, since it went pos, unfortunately. If it didn't look like a Ponzi before, it sure does now, it seems to me.
