The evolution of money-From barter to Bitcoin 2018

The only constant is change, or in other words, everything is constantly evolving, why would not many do it?

The barter

According to the liberal current of the economy founded by Adam Smith, barter, as a free exchange between individuals, is a natural practice of the human being, however, the difference between value and cost is something that has always existed and what for, you can be worth a lot to another person costs nothing.

The Anatolian Obsidians, used as raw material for Stone Age tools, were distributed as early as 12,500 BC. C., with an organized trade in the IX millennium a. C.4 5 In Sardinia, one of the four main sites with obsidian deposits in the Mediterranean, this trade was replaced in the third millennium BC. C. for the copper and silver trade.

Banks & credit cards

In the modern sense of the term, banking had its beginnings in Italy, in the rich cities of northern Italy, such as Florence, Venice and Genoa, at the end of the medieval period and the beginning of the Renaissance. The Bardi and Peruzzi families dominated banking in 14th century Florence and established branches in many other parts of Europe. Perhaps the most famous Italian bank was the Medici, founded by Juan de Médici.

The history of banking cards dates back to 1914 when it began with the Daparga Group family. That's when Western Union issued the first consumer credit card. These first cards were given to the company's preferred customers and offered a variety of special services, including deferred payment free of charge.

BITCOIN

Bitcoin is characterized by being decentralized, is not backed by any government or central bank, uses a work test system to prevent double spending (that's the same bitcoin is used several times) and reach consensus among all the nodes that make up the network exchanging information about an unreliable and potentially compromised network (resolves the problem of Byzantine generals) Transactions do not need intermediaries and the protocol is open source.

NOW

It's okay, but let's not be so hard on us, it took our ancestors almost 40 years to accept the credit cards and not even think how long it took them to accept the round land. So how long do you think it takes us to accept it? #acceptbitcoin
