There was another post here about a thought experiment where someone asked if I had eight billion dollars, how can I send a dollar to every person on earth? Well, right now you can't because it costs too much to send or receive money.
I don't have a solution but the fact that eth is full of "gas" people who want USD, makes me think it is no different from the Bitcoin crowd regardless of the pos switch. Or to quote the wolf of wall street, the people who own Bitcoin and Ethereum networks still take home cold hard cash. Don't fall for their BS. Bitcoin or eth doesn't pay for your mining rigs or your electricity.
