For example the word cake: A bitcoincash address consists of 42 characters: qpv44zw0....cake.....2elahdw5 Not sure if there is some kind of restriction on how many numbers can appear on a bitcoin cash address but for the shake of argument they are also in play completely random. A-Z , 1-9. TIL: Bitcoin addresses do not contain "0", "O", "l", or "I" to prevent mistyping addresses. I assume this probably will make it harder or easier :P Let's say that there aren't restrictions.
