Paper money in the US was issued by the continental congress to finance the revolutionary war in 1776.
The first currency had a few phases in the colonial and post revolutionary times. Because few coins were mined oops I mean minted.
Coins of course go back to the 5th century B.C according to greek historian Herodotus a contemporary of socrates and
the first ever recorded back packer so i say and the father of history as he is known. He was actually two centuries late as coins were first used in 7 B.C in modern Turkey Ldyias ancient kingdom made of mined gold and silvered called electrum, christ we haven't come far have we.
It soon spread to greek cities of coastal asia mining oops coastal asia minor then mainland greece then you can presume the rest of the world, it took some time but caught on quick,,,, ring any bells. Which brings us to today for it makes me happy to not have to do anymore research on old coins.
Someone said of the first paper money it wasn't worth the paper it was written on and it wouldn't last,,,,,any bells,so if coastal asia minor coins got us this far i think crypto mined coins will take us to infinity and beyond purely for two simple reasons they were the best and only idea around. Because money the mother fucker that it is past and the forseable future until someone comes up with a better idea,,,,,good luck with that. Thats why in my esteemed opinion crypto currencies is here to stay.
