RE: Is PEPECASH the Crypto of the FUTURE?

Fair point. Even Bitcoin Cash isn't actual cash.

1590s, "money box;" also "money in hand, coin," from French caisse "money box" (16c.), from Provençal caissa or Italian cassa, from Latin capsa "box" (see case (n.2)); originally the money box, but by 18c. the secondary sense of the money in it became sole meaning. https://www.etymonline.com/word/cash
