Cant remember which volume in Foundation but talks about how elite royal Families create their own currency and only accept it as legal barter.
It will be interesting when Apple tells us sorry only iCoins will be accepted for apple pay but have no fear all you have to do is sign "this" and exchange your gold for 1 million iCoins and you can have your iPhone working again.
A cashless society is the end to freedom- for me I will leave this planet paying with the greenback. I know humans are corrupt and greedy and I see no difference in cryptocurrency- it promises the next gen freedoms but in reality it is the end to it.
JAFO what do I know
