Why did people start using money?

Answer 1

they started out trading things that had a value all of their own but shaped so that the value could be known, gold silver and other metals shaped into coins were worth that amount because the material they were made of was worth that amount as the world became bigger and there was inflation in prices it began to be unwieldy to carry around sacks of coins for a loaf of bread so they began using representative money aka paper bills but it wasn't until recently that the bills were no longer based on the standard of what they stood for, such as the gold standard which meant that for every dollar issued by the us government there was that much worth of gold in its banks and forts Knox and stuff. going off the gold standard meant that the bills are only as good as the government that endorses them which is why there are exchange rates that fluctuate from time to time depending on how a country is doing monetarily.

basically they started using money to get a set standard of what some good or service is worth so that there was no need to have complicated trading going on
