New era has begun!
The first invention of money occurred in the 7th century BC. Well, this was due to a rule of economics: The Value of Something.
Before the invention of money, people traded through barter. For example, 100 apples would be purchased in exchange for a sheep. But the outcome was unclear. It was also difficult to determine. If a healthy sheep was worth 100 apples, how many apples would a sick sheep be worth? If we look at another example, how many watermelons would there be for 1 meter of fabric? There was confusion because there was no common unit that could be used to exchange different products. Complete uncertainty. There was no valuation method because one commodity had no common equivalent with another. As a result of their efforts to develop their civilization and turn to new inventions, people have produced a solution for this; Money. 
About 2300 years after all this time, something called the Internet was invented. People can access all information through data transfers, shop online, gamble, meet people, and do almost everything online, except for their basic needs such as eating and drinking water. What are the currencies they use to shop or trade with all this advanced technology? Do they still have to use dollars and euros? Does anyone still have to watch and know what they are doing? No! A person or a group named Satoshi Nakamoto took a step that would change the whole world. A big step towards complete privacy and change.
Just like Fatih Sultan Mehmet's conquest of Istanbul, just like the French Revolution. An old era has ended, a new era has opened!
