Barter economics more complex than currency.. thus auto

[11/2, 16:17] Dr. Harish Ravi: Cool the barter banks used to buy and stock say 10 1 kg parts of tomatos.. That guy would carry the paper and exchange one for potatoe etc and again buy from bank.. However everybody started depositing only multiple denomination coins after it came for ease of not having multiple credit notes..

[11/2, 16:55] Dr. Harish Ravi: As expected once the first bank was invented it was automatic that coins came.. economics leads to cascade of inventions !

[11/2, 16:56] Dr. Harish Ravi: Barter economics and was more complex so the easier thing got on quickly!
