Well in the mail you have to pay for the stamp. It's about a dollar. You could charge 10 cents...in fact, that's not a bad idea for a cryptocurrency.

Because the existing crypto currencies support 10c transactions if they grow to any kind of audience!

To be fair, if you bulk send via mail, you pay a very small fraction of normal postage.

A very small fraction.

4th class mail, sent to the occupant of every house, is very very cheap.

Really, the cost of adwork, logos, placement, 4 colour print is more expensive than post.

This was one of the original motivations to develop technologies that made cryptocurrency possible. Adam Back released the first proof-of-work implementation, Hashcash, in 1997 as a denial-of-service countermeasure.
