middle class in developed countries aren't going to pay $6,000 for 1/10th of something, or $600 for 1/100th of something.
And yet I know MANy that have, so clearly this is a completely false statement.
Maybe that's because most of the Middle Class is capable of understanding that they aren't getting a fraction of something? Right now $1 will get you more than 1,667 of something (satoshis, the spendable unit of the Bitcoin currency).
